THE PURCHASE OE COAL BY THE GOVERNMENT 

UNDER SPECIFICATIONS.

By GEORGE S. POPE.

INTRODUCTION.

SCOPE AND OBJECTS:

This bulletin is the third of a series a showing the results of government purchases of coal according to specifications as to its quality 

and giving typical forms of proposals for supplying coal and general 

information relating to government coal purchases.

Numerous calls for authentic information concerning the purchase 

of coal according to its heat value attest a, growing interest in the 

subject. Many of the commodities of life have long been purchased 

according to specifications requiring chemical or physical tests, or 

both, to determine whether the material delivered meets the requirements, the price to be paid depending on the results of the tests.

Until recent years coal consumers purchased coal merely on the 

statement of the dealer as to its quality, relying on his integrity and 

on the reputation of the mine or district from which the coal was 

obtained. It is surprising that the important question whether, value 

was being received for the money expended was not sooner seriously 

considered.

The purchase of coal by specification is an important step toward 

the conservation of our national mineral resources, for it results in 

an increased use of the lower grades of coal. The poorer coals find a 

market by competing with the better grades, not as to the price per 

ton but as to the cost of an equal number of heat units.

This paper gives in detail the results of government purchases of 

coal for the fiscal year 1908-9 and the list of contracts with abstracts 

of specifications for the fiscal year 1909-10, and summarizes the information on this subject obtained by the Survey. It is hoped that this 

information will promote a better understanding of the specification

PERSONNEL.

The work reported in this bulletin is under the general charge of 

J. A. Holmes, chief of the technologic branch of the United States 

Geological Survey, and H. M. Wilson, assistant chief technologist. 

The section of coal inspection, under the technologic branch, is 

charged with the duty of ascertaining the quality of coal delivered 

under specifications. For the fiscal year 1908-9, up. to March, 1909, 

J. S. Burrows had direction of the work of this section. On the 

resignation of Mr. Burrows in March the writer took charge, with 

P. M. Biefkin as first assistant and N. H. Snyder, F. J. Simington, 

A. A. Straub, Leo Loeb, E. W. Miller, W. J. Harris, jr., and H. H. 

McKee as inspectors and J. W. Peters as expert computer.

VALUE OF COAL AS FUEL.

REQUIREMENTS OF USE.

Coal is now burned for power production in gas producers and in 

boiler furnaces. For coals and lignites high in moisture or high in 

ash, the gas producer, used in connection with a gas engine, is best 

adapted to develop power, but for the generation of steam, which 

can be used for heating as well as for power, coal may be more conveniently burned in a specially constructed furnace under a boiler.

Coal is burned under boilers for producing power, for drying 

various materials, or for warming buildings. The most valuable coal, 

therefore, is that which gives up the most heat to the boiler for a given 

weight burned.

The value of a coal is indicated by the number of heat units it 

contains. This heating value is expressed in terms of British thermal 

units (abbreviated B. t. u.) per pound of coal, and is determined by 

means of a special apparatus called a calorimeter.

In purchasing coal for any power plant the aim should be to obtain 

a fuel which, all things considered (such as equipment, price of coal, 

and cost of labor and repairs), will produce a horsepower for the 

least cost. Experiments seem to indicate that almost any fuel may 

be burned with reasonable efficiency in a properly designed apparatus. The recognized requirements are as follows: (1) A uniform 

and continuous supply of fuel to the furnace; (2) an air supply 

slightly in excess of the theoretical amount required for complete 

combustion; (3) a temperature sufficiently high to ignite the gases 

that are driven off from the fuel; (4) a complete mixture of these 

gases with the air supplied before they reach a cooling surface, such 

as the shell or tubes of a boiler.
VALUE OF COAL AS FUEL. . 7 

FACTORS AFFECTING VALUE.

General statement. Some of the factors that may influence the 

commercial results obtained in a boiler are cost of the coal as determined by price and heating value, care in firing, design of the furnace 

and boiler setting, size of grate, formation of excessive amounts of 

clinker and ash, available draft, and size of the coal.

Moisture. Coal as mined contains more or less moisture. It is 

exposed to the air in shipment and may either dry out or be drenched 

by rain. The moisture in the coal .delivered is worthless to the 

purchaser and really costs him a considerable amount in freight and 

cartage and in the loss of the heat required for its evaporation in 

the furnace. If all coal contained the same proportion of moisture, 

or if the moisture in coal delivered by a given dealer were constant 

in amount, the purchaser's problem, -so far as this factor is concerned, 

would be simplified.

Under present conditions the moisture is an important element in 

the valuation of a ton of coal. It is evidently necessary to consider 

the coal just as it is received in order to determine its value to. the 

consumer, but chemical reports should be made on bo.th "dry coal" 

and "coal as received." The report on dry coal is convenient for 

comparing several coals to determine the relation of each element 

to the others; this report is important because the moisture in the 

same coal varies from day to day. The dry-coal report is also convenient for comparing the performance of boilers burning the same or 

similar coals. Of several coals having a similar composition, the one 

that has the least moisture and the least ash will generate the most 

steam when burned under a boiler.

Ash. Earthy matter and other impurities that will not burn are 

classed as ash. In commercial coals the proportion of ash may range 

from 4 to 25 per cent. Coals containing small percentages of ash are 

the most valuable, not only because of their correspondingly higher 

heating capacity, but because they offer less resistance to the free 

and uniform distribution of air through the bed of coal in the furnace. 

The labor and cost of managing the fires and of handling the ashes 

are also correspondingly less and are items to be considered in the 

choice of a coal. With the ordinary furnace equipment there may be 

a considerable loss of efficiency and capacity through a large percentage of ash. With some kinds of equipment it has been found 

that as the ash increases there is a decided drop in both efficiency 

and capacity. In some experiments made to determine the influence 

of excessive amounts of ash, coal containing as high as 40 per cent 

would generate no steam when fired on a chain grate, and therefore 

the efficiency and capacity of the plant would be zero.0 Such coal is

a Abbott, W. L., Some characteristics of coal as affecting performance with steam boilers, a paper read 

before the Western Society of Engineers, Chicago, 111.

not only worthless, but its use involves a direct expense, due to the 

cost of handling it. Whether the result would be similar with equipment other than a chain grate has not yet been determined. However, coals so high in ash that they are unsuited to boiler furnaces can 

be utilized in gas producers.

Volatile matter and fixed carbon. The volatile part of some coals, 

shown in the analyses, may be all combustible, but it generally contains some inert matter. The amount of this differs in different 

coals, and therefore it is impgssible to determine the heating value 

of any coal from its proximate analysis alone. Moreover, different 

coals that contain the same proportion of volatile matter do not 

behave alike in the furnace. In order to determine the value of one 

coal as compared with another for the same purpose it is important 

to know both the chemical composition and the British thermal units.

Of two coals of different character, the one that contains the 

higher proportion of fixed carbon is most easily burned, so as to 

give the maximum efficiency. However, if the coal containing the 

higher volatile matter is properly burned in a suitably designed 

furnace it may be made equally efficient.

Sulphur and clinker. Sulphur may be present in the free state, or, 

as is more common, in combination with iron or other elements. 

Other impurities with sulphur'often form a clinker that shuts out 

the air and increases the labor of handling the furnaces. It is possible, 

however, to burn coals containing up to 5 per cent .of sulphur 

without great difficulty from clinkers. A little steam introduced 

under the grate will relieve much of the trouble. Clinker may be due 

to other causes than sulphur, as any constituents of the ash which are 

easily fusible may produce it. There is need of further investigation 

to determine the influence of sulphur and the elements that form ash 

in furnace fires during combustion.

Size of coal. The size of the coal influences the capacity of anygiven 

equipment, owing to its effect on the draft. With a poor draft fine 

coal can not be burned in sufficient quantities to maintain the rated 

capacity. If thin fires are resorted to, the efficiency is usually 

lowered as a result of an excessive supply of air through holes in the 

fire. As a rule, when dust and very fine coal are fed into the furnace 

they either check the flow of air or are taken up by the draft and after 

being only partly burned are deposited back of the bridge wall; or 

they may pass up the stack, to the annoyance of people in the vicinity 

of the plant. If this dust is completely burned in passing through 

the furnace there is of course no loss of fuel. Coal of uniform size 

forms the most satisfactory fuel, as it does not pack so closely as coal 

of different sizes mixed.

In general it may be said that in any market the coal obtainable at 

the lowest price is the most economical, provided the furnace equip-

ment is suitable. If the furnace is not so designed as to permit the 

use of the cheaper coal it should be changed.

Heat units. The tests tend to show that, other conditions being 

equal, coals of similar composition are of value in proportion to the 

British thermal units, and the determination of these units in any 

coal will give approximately its value. It should be remembered, 

however, that the value of a coal for any particular plant is influenced 

by the character of the furnace, for all furnaces are not equally suitable for burning the many grades of coal. Aside from this factor, 

coals may be compared in terms of the British thermal units obtained 

for 1 cent, or on the cost per million heat units.

Summary. In the purchase of coal, then, attention should be 

given to the character of the furnace equipment and the load, the 

character of coal best suited to the plant conditions, the number of 

heat units obtainable for a unit price, the cost of handling the coal 

and ash, and the possibility of burning the coal without smoke or 

other objectionable features.

GENERAL PLAN FOR COAL PURCHASES UNDER SPECIFICATIONS.

HISTOKICAL STATEMENT.

Until the last few years little information has been available regarding the coals and the coal supply of the United States. Until such 

information was obtained the heat-value method of purchase could 

not be used, because its use requires a knowledge of the chemical 

and physical properties of the coals, indicating their calorific value 

as well as their behavior when being consumed.

The lack of such information was recognized in the establishment 

of the fuel-testing plant of the United States Geological Survey at 

St. Louis on the grounds of the Louisiana Purchase Exposition, in 

1904. Extended general investigations and a comprehensive study 

of the practical utilization of the coals have been made in this plant 

and its successors and in the coal fields. Similar investigations are 

now being made in Pittsburg, Pa. As a result of these investigations 

authentic information of great practical value has been made available for the government departments as well as the public, and it has 

been possible to establish the present rational method of purchasing 

a large part of the Government's coal supply.

A few years before the present system of coal buying was adopted 

the necessity for a uniform standard became apparent in some of 

the government departments, and the plan of purchasing coal according to its heat value was introduced. It proved successful, especially 

in the Treasury Department, under which coal is bought for postoffices and other public buildings throughout the United States.
10 PURCHASE OP COAL UNDER SPECIFICATIONS.

This work led to the development of general and uniform specifications for purchasing the government fuel supply. In an act making 

appropriations for sundry civil expenses for the fiscal year 1907, 

Congress recognized the importance of supervising more carefully 

the Government's coal purchases and charged the Geological Survey 

with the work of testing coal for government use. As a result of 

this legislation a form of specifications was drafted by engineers in 

the employ of the Government and in March, 1907, was approved 

by the national advisory board on fuels and structural materials. 

Contracts based on these .specifications went into effect July 1, 1907. 

Before an attempt was made to draft this form of specifications, the 

general fuel-testing investigations carried on at St. Louis, Mo., were 

supplemented by analyses and tests of a large number of samples of 

coal being delivered under contracts to buildings in Washington and 

elsewhere, and this work formed the basis for the standards set in 

the specifications. The same general form of specifications, modified 

by changes made as the result of their practical application, has since 

been in use.

ADVANTAGES OF DEFINITE SPECIFICATIONS.

Defects of the old plan. Under the old plan of purchasing coal, 

when the consumer had cause or thought he had cause to find fault 

with the quality of the fuel he received, he was assured that it must be 

good because, like all the other coal sent him, it came from a mine 

with an established reputation. Such a state of affairs made it 

difficult to take advantage of the competition which usually results 

when a considerable number of bidders are asked to submit prices. 

The purchaser was afraid to buy from any dealers but those he knew 

and trusted, because, although each dealer claimed that his coal 

was equal in quality to that of the others, yet if it did not prove to 

be satisfactory there was no standard for settlement or for cancellation of the contract. Many thousands of dollars worth of coal is 

bought each year in this manner, yet a buyer or investor would 

consider it absurd to make a contract for a building with no specifications other than that it should be of a certain size and well constructed. Neither would he buy gold, silver, or even copper and 

iron ores on the mere information that they were mined at certain 

localities. All products of mines are now purchased to a great extent 

according to their value, as shown by chemical analysis. This is 

true of coal in only a small degree, but the number of coal contracts 

made on this basis is increasing every year.

The purchase of coal under specifications is as advantageous as a 

definite understanding regarding the quality and other features of 

any other product, or of a building operation or engineering project. 

The man who buys under specifications gets what he pays for and 

pays for what he gets.
GENERAL PLAN FOE COAL PURCHASES. 11

Standard of quality. When the bidder is allowed to specify the 

quality of the coal he proposes to furnish, as determined by chemical 

analysis, he is placed on a strictly competitive basis with other bidders. 

Such a procedure broadens the field for both the bidder and the purchaser. It makes the bidder's proposal, when accepted, a contract 

that specifies an established standard of quality. This furnishes a 

basis for settling disputes regarding the quality of the coal delivered 

. and the price to be paid if the fuel is either better or poorer than has 

been guaranteed. If other coal must be substituted, as often happens, 

there is a standard for settlement. If the coal is uniformly poorer 

than the standard as specified there is a basis for cancellation of the 

contract.

The quality of coal from a given mine may vary from time to time 

through the failure of the miners to reject impurities; or the physical 

and chemical character of the coal of a certain bed may vary from 

place to place. In some coal fields different beds of coalare mined 

at the same time and the output is mixed. When there is need of 

preparation, as by picking slate and other impurities, or jigging or 

washing, the quality or value of the coal marketed depends a great 

deal on the care taken in the processes employed. The mining companies are responsible in a large measure for variations in the grade 

of prepared coal. The purchase of coal under a contract that distinctly specifies its quality stimulates the operator to prepare coal 

better before shipping it to market. Examples of fluctuation in quality 

are furnished by the table on pages 47-76, which show variations 

both in ash and in British thermal units of coal delivered.

Nature of specifications. Government specifications are drawn with 

a view to the consideration of price and quality. For manufactured 

articles and materials of constant and uniform quality they generally 

can be reduced to a clear and simple statement of what is desired, 

but for coal, which may be considered a finished product when loaded 

on the railroad cars at the mine, the great and obscure variation in 

character makes a simple requirement impracticable, and this fact 

is recognized and provided for in the coal specifications prepared by 

the Geological Survey. Under these specifications bidders are 

requested to quote prices on the various sizes of anthracite, a definite 

standard of quality being specified for each size, and to state the 

standard of quality and price for bituminous coal. Awards are then 

made to the lowest responsible bidder for anthracite and to the bidder 

offering the best bituminous coal for the lowest price, the amount 

finally paid being determined by the tests made under the terms of 

the specifications. The specifications become part of the contract, 

and payment for coal delivered is made according to the standard of 

quality fixed. The actual quality and value of coal delivered is 

determined by analysis and test of representative samples taken in a
12 PURCHASE OF COAL UNDER SPECIFICATIONS.

specified manner by agents of the Government and analyzed in the 

government fuel-testing laboratory at Washington. For coal of 

better quality than the standard the contractor is paid a bonus proportional to its excess of value. For coal of poorer quality than the 

standard, deductions are made from the contract price proportional 

to its deficiency in value.

It evidently will not be satisfactory to either the buyer or the seller 

to establish a standard for the coal unless the liability to variation 

is recognized and provision made for settlement when the coal is 

better or poorer than the standard. Experience with any method of 

buying coal shows that it will seldom be rejected when of poor quality, because of the difficulty, delay, and cost of removing it from 

the bins. The buyer is often confronted with the alternative of 

burning the coal delivered or going without fuel until more can be 

procured. Unless the coal is very bad it is usually expedient to use 

it and pay a smaller price. This is also more favorable to the contractor, as to remove the coal would be costly and it would not be 

satisfactory as fuel to any other customer.

. Summary of advantages. The advantages of purchasing coal under 

specifications may be briefly summarized as follows:

(1) Bidders are placed on a strictly competitive basis as regards 

quality as well as- price. This simplifies the selection of the most 

desirable bid and minimizes controversy and criticism in making 

awards.

(2) The field for both the Government and dealers is broadened, 

as trade names are ignored and comparatively unknown coals offered 

by responsible bidders may be accepted without detriment to the 

Government.

(3) The Government is insured against the delivery of poor and 

dirty coal, and is saved from disputes arising from condemnation 

based on the usual visual inspection.

(4) Experience with the old form of government contract shows 

that it is not always expedient to reject poor coal, becaus.e of the 

difficulty, delay, and cost of removal. Under the present system 

rejectable coal may be accepted at a greatly reduced price.

(5) A definite basis for the cancellation of contract is provided.

(6) The constant inspection and analysis of the coal delivered 

furnishes a check on the practical results obtained in burning the coal.

GROWTH OP THE SYSTEM.

Contracts for the fiscal year 1908-9 under which the United States. 

Geological Survey was called upon to make tests and analyses covered 

611,362 tons, at an estimated cost of $1,858,750; those for the fiscal 

year 1909-10 covered 829,289 tons, at an estimated cost of $2,286,800.
METHODS OF SAMPLING AND TESTING. 13

A few government stations have their own laboratories for analyzing 

and testing coal delivered under specifications. The number of tons 

and cost covered by these contracts would somewhat increase the 

quantities and values above given.

METHODS OF SAMPLING AND TESTING.

MINE AND CAR SAMPLES.

Comparative study. In connection with the study of the coal 

deposits of the country and the best methods to prevent waste in 

mining and utilizing the coal supply, trained inspectors of the United 

States Geological Survey have visited about a thousand mines in all 

of the coal-producing States and Territories, taking two or more 

samples from each mine. A study of the analyses of these samples 

and of samples taken from cars shipped from more than 200 mines

shows that the mine samples are as a rule better than the average 

coal shipped in cars. The average coal delivered contains about 

one-third more ash than the mine sample. This difference is due to 

the fact that the trained government inspector is able to free' most 

of the small mine samples more completely of bone, slate, and other 

extraneous matter than the miner, who endeavors to get the maximum number of tons past the tipple inspection, the nature of which is 

presumably determined by trade and market conditions. Most of the 

samples collected by the government inspectors from the mines show 

a higher moisture content than the commercial samples, because of 

the precaution taken by the inspectors to prevent loss of moisture in 

the collection, preparation, and analysis of the mine sample.

When properly taken, mine samples indicate the general character 

of the coal and enable one to determine its probable value for any 

designated purpose.

Samples taken from railroad cars should not be limited to a few 

shovelfuls of coal procured from the top of the car, for the quality of 

the coal may not be the same throughout the car; indeed, it is sometimes found that the heavier pieces have gradually shifted in transit 

toward the bottom. Tests of samples taken at the bottom of a car 

ha_ve shown as much as 8 per cent more ash than samples taken at the 

top. The moisture content also may vary from, top to bottom, depending on the weather. The only way to get a fair sample is to 

take a number of shovelfuls of coal from different points in the car 

when the coal is unloaded, so as to procure a representative portion 

of the coal from top to bottom and from end to end.

Weight of sample. The number of pounds to be taken as a fair 

sample of a given lot of coal varies according to the size, character, 

and condition of the coal and depends also upon the character and 

amount of the extraneous matter as well as on the size of the particles
14 PURCHASE OF COAL UNDER SPECIFICATIONS.

of both coal and impurities. It is therefore evident that the sampling 

should not b6 left to an inexperienced person, but should be done by 

one who is thoroughly familiar with the significance of the factors 

just stated and who has some intimate knowledge of the coal to be 

sampled.

MOISTURE CONTENT OF THE COAL.

Adjustment of price to weight. Bituminous coal when exposed to 

the air gradually depreciates in heating value, owing to loss of volatile 

matter, but aside from this loss a car of coal should represent the 

same total number of heat units when it reaches its destination as 

when-it started. If rain falls on the coal it will become heavier and a 

greater number of pounds will be delivered, but each pound will have 

a correspondingly lower heat value. On the other hand, if the 

weather is fair and the coal dries out on the way, it will weigh less 

and the heating value of each pound will be correspondingly higher. 

In other words, under specifications such as are used by the Government, neither the dealer nor the purchaser will gain or lose by change 

in the moisture content of the coal between the time it is weighed at 

the mine and the time it is weighed on delivery. The price per ton 

will be correspondingly lower if the coal is wet and higher if the coal 

is dry.

Practical considerations. -The number of heat units per pound of 

coal "as received" varies in inverse proportion to the variation in 

its content of moisture, so that for a correct determination of the 

price to be paid for the coal it is important that the sample analyzed 

should contain the same percentage of moisture that existed in the 

coal delivered. It is physically impossible to preserve the same actual 

amount of moisture in the sample, for in being prepared for the laboratory it is exposed to conditions that tend to vary its content of moisture. The crushing and quartering 'of the original sample exposes 

a greater surface to the action of the air, so that even under the most 

satisfactory conditions it is probable that the percentage of moisture 

in the sample will be less than the percentage of moisture in the coal 

weighed at the point of delivery.

This variation favors the coal dealer, for a decrease in the moisture 

content of the sample below the moisture in the coal delivered represents so much gain in heating value, which increases the price he will 

receive for the coal.

In coals in which the difference between the moisture in a carload 

and the percentage of moisture in the air-dried sample is relatively 

small, and in coals that are easily and quickly sampled and worked 

down to a laboratory sample, this error is so small that it is practically 

negligible. It is with coals in which the moisture difference from 

time to time is relatively large that trouble is experienced, for it is
METHODS OF SAMPLING AND TESTING. 15

difficult to determine exactly the amount of moisture in these coals 

as weighed for delivery.

It is therefore evident that a careful and uniform method of sampling coal and preparing and analyzing samples should be followed 

in order that the variations in moisture may be reduced to a minimum.

The moisture in an air-dried sample is that remaining after the 

coal has been reduced to a prescribed size and has been exposed to a 

prescribed temperature or to specified conditions for a stated period 

of time. The air-dried condition is virtually a "moisture-balanced" 

one, depending on the temperature, humidity, and barometric pressure 

in the laboratory. The percentage of moisture in the air-dried sample 

is a function of the physical and chemical character of the coal. The 

minimum percentage is found in anthracite and semibituminous 

coals, and the proportion increases as the grade of coal decreases, 

becoming higher and higher in bituminous, subbituminous, and 

lignite.

Samples of coal that is purchased "as received" should not be 

taken from coal in the boiler room, for this coal has been exposed to 

relatively high temperatures; neither should samples be stored in the 

boiler room, as they will inevitably lose moisture and such loss may 

materially affect the price paid for wet coals. The drier the coal 

that is fed to the furnace the greater the. evaporation per pound of 

coal, for less heat i$ required to evaporate the water in dry coal, but 

this is a matter of efficiency of plant and not of economy of purchase, 

though the two are often confused.

PROCEDURE IN PRACTICE. 

IN WASHINGTON.

Gathering samples. Whenever a delivery of coal is to be made at 

one of the department buildings in Washington an inspector is sent 

to remain during the unloading of the coal. This inspector is provided with galvanized-iron buckets, each large enough to hold about 

65 pounds of coal and equipped with closely-fitting lid and lock. 

In these buckets portions of coal taken from every part of the lot 

delivered are placed, care being taken that the samples shall truly 

represent the coal delivered. These samples are secured by locking 

the buckets, which are immediately delivered to the crushing or 

sampling room in the United States Geological Survey building.

Preparation of samples. Machinery for preparing the collected 

samples is installed in the crushing room. The large samples, weighing 65 to 200 pounds (the weight depending on the character of the 

coal and the amount delivered), are put through a motor-driven 

baby hammer crusher, which has a capacity of about 1 ton of furnace anthracite coal per hour. This machine crushes the coal to a
16 PURCHASE OF COAL, UNDER SPECIFICATIONS.

size that will pass through a |-inch mesh. An arrangement of automatic riffles mechanically quarters the crushed coal. The quarter 

thus separated is then put through a portable mechanical sampler 

or riffle and reduced to a portion weighing 2 pounds, and is then 

hermetically sealed in a 3 by 9 inch cylindrical can bearing the 

number of the gross sample.

If the coal of the 2-pound sample will not pass through a £-inch 

mesh and the coal of some samples taken outside of Washington 

will not it is reduced to the proper fineness by means of an adjustable chipmunk jaw crusher.

The 2-pound sample is next reduced to 20-mesh fineness in a roll 

crusher and a 2-ounce portion is segregated and placed in a rubberstoppered bottle preparatory to determining its content of moisture. 

The 20-mesh coal is then thoroughly mixed, after which it is passed 

through riffles and reduced in quantity to about 2 ounces. This 

2-ounce sample is further reduced in fineness on a bucking board 

until all its particles will pass through a 60-mesh screen. It is then 

placed in a rubber-stoppered bottle and sent to the laboratory for 

analysis. During this process of reduction the sample has unavoidably become partially air dried, but accuracy in calculation to its 

condition "as received" is insured by using for this purpose the 

segregated 2-ounce portion referred to above.

Removal of dust. Much objectionable dust is produced during the 

process of crushing. To prevent this dust from escaping to circulate 

about the building the wooden partitions and doors of the crushing 

room are covered with sheet iron, a system of hoods and pipes collects and carries the dust-laden air to the main furnace stack of the 

building, and a fan draws fresh air into the room.

Laboratory treatment. On its receipt each sample is numbered and 

the record identifies this new number with the serial numbers that 

the sample has borne at each stage of its earlier history. The method 

of analysis is that adopted by the American Chemical Society. The 

calorific value is determined with a bomb calorimeter. The results 

of the analysis are reported to the coal-inspection section for use in 

the public service.

OUTSIDE OF WASHINGTON.

Samples of coal delivered to points outside of Washington are 

taken in accordance with instructions furnished by representatives 

of the department for which the coal is purchased. With few exceptions the samples are crushed by hand, prepared, and reduced to. 

quantities weighing about 2 pounds. Each sample is placed in, a 

cylindrical galvanized-iron can 9 inches in length and 3 inches in 

diameter, with a screw cap 2 inches in diameter. This can is immediately sealed air-tight by wrapping several turns of electrician's 

adhesive tape around the connection of the cap and can. A wrapper

bearing marks of identification is put on the can and it is sent by 

mail or express to the coal-inspection section of the United States 

Geological Survey, at Washington, for analysis of the sample. Detailed 

information to be placed on record is sent under a separate cover for 

the identification of the sample.

GENERAL DIRECTIONS FOR SAMPLING.

Need of experience and caution. Persons who have had no experience 

in taking samples are liable to select a sample better than the average 

run of the coal. ' Occasionally a lump of coal is broken and shipped 

to the laboratory in a cloth sack, which allows the moisture to dry 

out; moreover, the lump selected is usually free from layers of slate 

and impurities, and of course then represents the best coal in the lot 

rather than the average, and its analysis will show a higher value than 

the coal delivered. Especial care should be exercised to note the 

proportion of slate and other foreign substances, in order that such 

impurities may be included in the sample in the same proportion. 

Experience and good judgment on the part of the sampler are necessary to insure the collection of a representative sample; and it is well 

to remember that as the larger lumps of coal roll down and collect 

near the bottom of a pile or load a sample taken entirely from near 

the floor would not fairly represent the whole.

Loss of moisture in samples. In spite of every precaution taken 

to prevent loss of moisture during the collection, preparation, and 

analyses of samples, it is certain that loss of moisture may occur, 

whereby the heat value of the coal as shown by analysis of the 

sample is greater than that of the coal from which the sample was 

taken. It is important to the purchaser and fair to the dealer that 

the quality should be determined on the coal "as received." In the 

interest of equity, therefore, the suggestions that follow are presented for the guidance of those who wish to send samples to a 

laboratory for analysis.

Wagoriload deliveries. Samples taken from coal delivered at a 

department building should consist of a shovelful of coal taken from 

each wagonload or from each third or fifth load, the number of 

samples taken depending on the loads delivered. It is important 

to obtain representative portions of coal from every part of the 

delivery, so that the samples will show the quality of the delivery or 

order as a whole. The sample should contain about the same proportion of lump and fine coal that is contained in the coal as delivered.

If the quantity delivered is 100 tons or more, at. least two samples

should be taken, one representing the earlier and the other the later

delivery. The average of two or more analyses will represent more

accurately the quality of the coal than a single analysis, because it

34827 Bull. 428 10 2
18 PURCHASE OF COAL UNDER SPECIFICATIONS.

is difficult to preserve the character of the large sample in reducing 

it to the small sample required for laboratory use.

Cargo deliveries. In determining definitely the number of samples 

to be taken to represent different quantities delivered many variable 

factors must be considered. For cargoes of 4,000 to 6,000 tons the 

approved method is to take a sample of about 65 pounds from every 

third railroad car when unloaded; three such samples, representing 

nine cars, are mixed and reduced by quartering to the regular 2- 

pound sample. By this procedure 8 to 14 samples are obtained for 

the cargo. An analysis representing the whole cargo is obtained 

by averaging the results of analyses. It is impracticable to take a 

single large sample to be fairly representative and reduce it to a 

2-pound sample for laboratory treatment, for the analysis of a single 

sample would probably not correctly represent the quality of the 

whole of a large cargo. .

Stowage and quartering down. A gross sample should, when taken, 

be immediately placed in a metal receptacle having a tight-fitting 

cover and a first-class lock, and when samples are being quartered 

down each receptacle should be securely locked and the key held by 

a responsible employee. The receptacle should be placed in a comparatively cool place to minimize loss of moisture from the sample; 

and for the same reason the process of quartering down and preparing samples for shipment to the chemical laboratory should be 

carried on as rapidly as possible. This process, briefly described, is 

as follows:

The contents of the receptacle or receptacles are emptied in a clean, 

dry space, preferably on a sheet-iron plate of suitable dimensions, so 

located as to prevent admixture of foreign matter with the sample 

during its preparation. All the lumps are then broken by a maul 

or sledge until they will pass through a half-inch mesh. The mass 

is then thoroughly mixed, formed in a conical pile, and equally quartered by means of a shovel or board. Two opposite sections are next 

rejected and the remaining sections are mixed. The pile is then reformed and opposite quarters are discarded as before. This process 

is continued until only about 2 pounds remain. This final sample 

is immediately placed in a suitable receptacle for shipping and is 

sealed air tight. The metal can in use by the United States Geological Survey for this purpose is 9 inches high and 3 inches in diameter.

Shipment. The 2-pound samples thus prepared should be forwarded promptly and notice of shipment sent under separate cover. 

Receptacles should be marked plainly on the outside and a corresponding number or description should be placed inside. A complete record of all deliveries should be kept, showing dates, names 

of contractor, kind of coal, total weight delivered, condition of coal 

(wet or dry), and any other important details.
PUECHASE OF COAL UNDER SPECIFICATIONS. 19 

THE GOVERNMENT AS A COAL CONSUMER. 

EXTENT OF GOVERNMENT PURCHASES.

The United States Government purchases annually from $6,500,000 

to $7,000,000 worth of fuel. This sum includes the cost of delivery 

and of stowage. Each department buys coal through its purchasing 

officers. The Navy, War, Treasury, Interior, and Commerce and 

Labor departments are large consumers of coal. Much of the coal 

used by the Government must be delivered by wagon, and the business is therefore limited to dealers having hauling facilities. This 

is especially, the case in the city of Washington, where coal is purchased principally for heating the public buildings.

The Treasury Department is a large consumer of coal delivered in 

wagons, for the fuel required for post-offices, custom-houses, United 

States court-houses, marine hospitals, mints, and other federal buildings throughout the country is purchased by this department, which 

also buys for the Kevenue-Cutter Service.

The Navy Department is a large car-lot consumer as well as a purchaser of large cargoes of coal for foreign delivery. The Bureau of 

Supplies and Accounts of this department purchases the larger 

quantities for the ships of the navy and the c.ar lots for use in the 

navy-yards.

The War Department makes purchases of coal for the many forts 

and army posts in the United States and foreign possessions and for 

the ships in the army transport service. The car-lot consumers are 

the Ordnance Department, which buys coal for the arsenals, and the 

Engineer Corps, which buys fuel for use in river and harbor improvement and other construction work.

Coal for use in the Canal Zone, Isthmus of Panama, is purchased 

by the Panama Railway Company of< New York f. o. b. at an 

Atlantic port in the United States, being shipped at present from 

Norfolk, Va.

The Department of Commerce and Labor purchases coal for the 

vessels of the Coast and Goedetic Survey and for the Immigration 

Service. At the Ellis Island immigration station, New York, 10,000 

tons, mostly bituminous coal, is bought annually. Fuel for the 

light-houses is purchased by this department, the service being 

divided into sixteen districts, for each of which a separate contract is 

made. Each of these contracts covers 1,000 to 13,000 tons and calls 

for anthracite or bituminous coal. The Bureau of Fisheries is a consumer of anthracite and bituminous coal in small lots, delivered to 

the cars of the bureau and to its stations throughput the country.

The Interior Department is a large consumer of coal in Washington, where it purchases annually 20,000 tons of bituminous and 

1,000 tons of anthracite coal for the Government Hospital for the
20 PURCHASE OF COAL UNDER SPECIFICATIONS.

Insane. Outside of Washington this department's most important 

contracts are those for coal to be delivered to Indian schools and 

agencies.

. Most of the coal purchased by the Government is used for warming public buildings and for generating power, though small quantities of blacksmith's or forge coal and coke are bought. The larger 

individual contracts are those for bituminous coal and the small 

sizes of anthracite. The larger sizes of anthracite are, as a rule, purchased in small lots and delivered mainly by wagons.

PRACTICE IN THE TREASURY DEPARTMENT.

AWARD OF CONTRACTS. 

COMPARISON OF HEATING VALUES.

An important point which seems not to be thoroughly understood 

is the manner of making awards in purchasing coal according to its 

heating value. In order to show how the lowest bid is determined, 

the proposals for supplying coal to the federal buildings under the 

Treasury Department have been selected as representing the widest 

range of coals and conditions throughout the country.

All bids are received on official proposal blanks, in sealed envelopes, 

in response to advertisements inserted in the daily papers. These 

bids are opened at a specified time, in the presence of all who desire 

to attend, and awards are made as soon thereafter as possible.

In order to make a proper award of contract it is necessary to 

reduce the proposals to a common basis for comparison. This may 

be done in several ways, but the method chosen is to adjust all bids 

on a given lot of coal to the same ash percentage by selecting as the 

standard the proposal that offers the coal containing the lowest percentage of ash. Each 1 per cent of ash content above that of this

standard is assumed to have a negative value of 2 cents a ton, the 

amount of the penalty which is exacted under the contract requirements for 1 per cent excess of ash. The proposal prices are all adjusted in this manner and are so tabulated. On the basis of the 

adjusted price, allowance is then made for the varying heat values 

by computing the cost of 1,000,000 British thermal units for each 

coal offered. In this way the three variables calorific value, percentage of ash, and basic price per ton are all merged into one figure, 

the cost of 1,000,000 British thermal units, by which one bid may be 

readily compared with another.

For example, take two bids received for coal in Boston, as follows:

. 13595

The percentage of ash (column 4) in E is taken as a standard of 

comparison, and the determined ash in B is shown to be 1.21 per 

cent higher. Each 1 per cent of ash difference from the contract 

Standard is SO rated as to make 2 cents difference in the price per ton; 

1.21 per cent of ash is valued at $0.02x1.21, or $0.0242; bid B is 

therefore increased to $4.3242 per ton (column 6). The two bids 

are then on an equivalent basis, so far as ash is concerned.

The heating values being different, it is desirable to compute the 

calorific cost by the formula:

1,000,000 X price per ton 

2,240 XB. t. u.

= cost per 1,000,000 B. t. u.

This computation shows the cost of 1,000,000 B. t. u. to be 

In the case of E 

1,000,000X84.19 

2,240X14,327 = $0.13056.

In the case of B1,000,000 X $4.3242 

2,240X14,200 = $0.13595.

In like manner the cost of 1,000,000 British thermal units is calculated for each bid received under the proposal, and the results are 

entered for ready comparison in column 7 of the table.

The necessity for having such a basis of comparison is evident 

from an examination of the bids for coal to be delivered on any of the 

contracts. For instance, in Chicago nine bids were received with 

guaranties of British thermal units from 11,094 to 14,800, and of ash 

from 6 to 10 per cent, while the prices ranged from $2.80 to $4.10. 

Notwithstanding these apparent discrepancies, the cost of 1,000,000 

British thermal units ranged only from 11.328 to 12.657 cents.

It has been found desirable to award some contracts to bidders 

other than those naming the lowest price per ton. Should two or 

more proposals appear equally advantageous, the relative suitability
r

22 PURCHASE OF COAL UNDER SPECIFICATIONS.

of the coals for use with the plant to be supplied with fuel may be 

determined by actual trial tests. An examination of the table on 

pages 23-32 should dispel any doubt as to the general applicability of 

the specifications to a wide range of coals delivered in different 

localities under varying conditions. This table shows the results of 

analyses of coals mined in ten States Pennsylvania, Maryland, 

West Virginia, Illinois, Kentucky, Tennessee, Alabama, Kansas, 

Virginia, and Colorado and includes small sizes of anthracite and 

low and high volatile bituminous and semibituminous coal.

Coals from Pennsylvania, Kentucky, Virginia, and Tennessee compete in Louisville; from West Virginia, Virginia, and Pennsylvania 

in Toledo; from Illinois, Kentucky, Pennsylvania, and West Virginia in Minneapolis, etc., and fall within the specification limits 

especially fixed in each city.

OTHER FACTORS.

While calorific rating allows an award to be made to the best 

economic advantage, other factors than the mere theoretical heating 

value of the coal may, under certain conditions, have considerable 

weight, .especially where uncertainty exists as to the suitability or 

adaptability of an untried, coal to the plant for which it is purchased, 

and the consideration of this question must take into account the 

conditions of furnaces, grates, and draft, the labor of handling coal 

and ash, the storage facilities, etc.

In plants where boiler capacity and grate area are small or draft is 

weak, only the best grades of coal can be burned, and it is therefore 

desirable to take bids for coal to be used in such plants on a general 

specification, so as to determine the result of making radical changes 

in the plant to take advantage of the coal that will give the best 

economic results.

The relative facilities, competency, and responsibility of the competing firms must, of course, also be considered in making awards.

THE GOVERNMENT AS A COAL CONSUMER. 33 

SPECIFICATIONS FOR THE FISCAL YEAR 1909-10. 

GENERAL CHARACTER.

The current contracts for coal purchased according to its heat value, 

which have been arranged alphabetically by cities in the table on 

pages 41-45, will serve as a guide for bidding on coal contracts for the 

fiscal year 1911. These contracts are all accompanied by the specifications given on pages 34-40.

Two classes of coal, anthracite and bituminous, are recognized and 

differentiated in the specifications. By anthracite is meant the coal 

mined in Susquehanna, Lackawanna, Luzerne, Carbon, Schuylkill, 

Columbia, Sullivan, Northumberland, and Dauphin counties, Pa. 

. By bituminous coal is meant varieties other than anthracite, including 

the several grades of semibituminous and semianthracite.

The specifications for anthracite provide definite standards of 

quality for each size. These standards so far have been based on the 

percentage of ash in dry coal. In this connection it is well to know 

that the term " dry coal " means coal free from moisture, as determined 

by drying a small sample at 105° C. It is obvious that the percentage 

of ash in dry coal must be somewhat higher than in the undried 

sample.

Some of the anthracite coal bought for the Treasury Department is 

purchased on the specifications used for bituminous coal, whicja provide for payment according to the percentage of ash in " dry coal" and 

the number of British thermal units in coal "as received." It is 

probable that nearly all of the anthracite coal purchased during the 

fiscal year 1910-11 and future years will be purchased according to 

the double standard.

The specifications for bituminous coal are intended to describe 

clearly the character of the coal desired by the Government and to 

obtain from the bidder a definite statement of the quality of coal 

offered, with a view to using such statement,as a standard, or as a 

basis for payment in connection with the price stated.

As will be seen from the specifications for bituminous coal, the 

bidder is not .required to submit a sample of his coal, but is expected 

to state the percentage of ash in the "dry coal" and the number of 

British thermal units in the coal as it is to be delivered. If the 

bidder does not know the value of his coal, he may arrange to submit 

a properly selected sample with his bid, this sample to be analyzed by 

the Government and the results to be used as a standard under the 

contract. It is preferred, however, that the bidder give his own 

values.

The limits fixed in the specifications in the interest of plant economy 

are wide enough to permit the use of the output of any mine or group 

of mines, provided proper care is exercised in mining and picking out 

34827 Bull, 428 10 3
34 PURCHASE OF COAL UNDER SPECIFICATIONS.

slate, bone, and other impurities. With these points in mind, it is 

only necessary for the bidder to select coal that will meet the description given and permit deliveries within the limits set.

It is not expected that all deliveries will be absolutely uniform or 

agree exactly with the standards established by the contractor, but 

it is necessary that all deliveries shall be within the limits set by the 

Government.

The standards established by the contractor should, however, be 

such as to require the least possible correction in price on account of 

variation in ash and heat units.

The heating value; expressed in British thermal units, of coal containing approximately the same percentage of ash is essentially a 

direct measure of its actual value to the purchaser, and for this reason 

the specifications provide for payment in proportion to the number 

of heat units contained in the coal as received. As the coal is weighed 

when delivered and payments are made according to the price per 

ton, it is necessary to determine the heat value of the coal in the condition in which it is received,- with whatever moisture it may then 

contain.

Under this plan neither the contractor nor the Government will 

gain or lose by change in the moisture content of the coal between the 

time it is weighed at the mine and the time it is weighed on delivery. 

The price per ton will be correspondingly lower if the coal is wet, and 

higher if it is dry.

A further correction in payment is made for variation of the ash in 

dry coal in order to take account of the cost of handling additional 

fuel and ash and its effect on the capacity of the boiler and furnace.

FOEM OF SPECIFICATIONS AND PROPOSAL.

The following is the general form of advertisement, including specifications, schedule, proposal, and guaranty, used in inviting bids for 

furnishing coal for the Government in the District of Columbia. 

Suitable modifications of these forms are used in other cities.

SPECIFICATIONS FOR SUPPLYING COAL FOR THE EXECUTIVE DEPARTMENTS AND 

INDEPENDENT ESTABLISHMENTS OF THE GOVERNMENT.

, OFFICE OF GENERAL SUPPLY COMMITTEE,

Washington, D. C., ............

Sealed proposals, in triplicate, to furnish, the quantities of coal specified in the 

schedule herewith, required for use of the [name of department, bureau, or institution] for the fiscal year ending June 30, 19.., will be received until 2 o'clock p. m. 

...., 19.., at the office of the general supply committee, Washington, D. C., and

then opened.

Each bidder shall have the right to be present either in person or by attorney when, 

the bids are opened.

ADDRESS OF PROPOSALS.

Proposals in triplicate must be forwarded to the general supply committee, Washington, D. C., postage prepaid. Addressed envelope for mailing is inclosed herewith.
THE GOVERNMENT AS A COAL CONSUMER. 35

PROPOSALS GUARANTY.

Proposals must be made in triplicate on the for-m furnished by the general supply 

committee, and must be signed by the individual, partnership, or corporation making 

the same; when made by a partnership, the name of each partner must be signed. 

If made by a corporation, proposals must be signed by the officer thereof authorized 

to bind it by contract, and be accompanied by a copy, under seal, of his authority to 

sign. " . .

The proposals must be accompanied by a guaranty from a corporate surety, duly 

qualified under the act of Congress approved August 13, 1894, or a guaranty signed 

by at least two responsible guarantors, that the bidder shall, within ten days after 

being called upon to do so, execute contracts in accordance with the terms of the 

proposal, and give a bond for the faithful performance thereof, with good and sufficient sureties as hereinafter required. The responsibility and sufficiency of the 

signers of such guaranty must be certified to by a judge or a clerk of a court of record 

or a United States attorney at or nearest to the place of business of the bidder. The 

guaranty must be in the penal sum of 10 per cent of.the total amount of the bid: Provided, That $10,000 will be accepted as sufficient guaranty for a total bid of $100,000 

or more. If preferred, a certified check for like amount, payable to the Secretary 

of the Treasury, may be filed in lieu of guaranty, the amount of said check to be 

forfeited to the Government in the event of failure on the part of the bidder to enter 

into contract in accordance with the proposal.

AWARD.

Bids will be considered on each item and on each building separately; and in 

determining the award of the contract consideration will be given to the quality 

of the coal (expressed in terms of ash in "dry coal" and British thermal units in 

coal "as received") offered by the respective bidders, the ability of the contractors 

to furnish the coal,.and the responsibility of the parties submitting bids, as well as 

to the price per ton.

If the bidder to whom the first award may be made should fail to enter into a 

contract as herein provided, then the award may be annulled, and contract let to 

the next most desirable bidder, and such bidder shall be required to fulfill every 

stipulation embraced herein, as if he were the original party to whom the contract 

was awarded.

None of the contracts can in any case be lawfully transferred or assigned.

Contracts will be awarded only to established dealers in coal.

No proposal will be considered from any person, firm, or corporation in default 

of the performance of any contract or agreement made with the United States, or 

that is conclusively shown to have failed to perform satisfactorily such contract or 

agreement.

CONTRACTOR'S BOND.

Each contractor will be required to give bond with two or more individual sureties 

or one corporate surety (the latter preferred) duly qualified under the act of Congress 

approved August 13, 1894, in which they shall covenant and agree that, in case the 

said contractor shall fail to do or perform any or all of the covenants, stipulations, 

and agreements of said contract on the part of the said contractor to be performed as 

therein set forth, the said contractor and his sureties shall forfeit and pay to the United 

States of America the sum specified in said bond, to wit, a sum equal to 25 per cent 

of the estimated amount of the contract, for which said forfeiture the said contractor 

and his sureties shall be jointly and severally liable as fixed, settled, and liquidated 

damages, and not as a penalty, to be sued for in the name of the United States. Such 

sureties (except corporate sureties) shall justify their responsibility by affidavit showing that they severally own and possess property of the clear value in the aggregate
36 PURCHASE OF COAL UNDER SPECIFICATIONS.

of double the amount of the above-mentioned forfeiture over and above all debts 

and liabilities and all property by law exempt from execution; to be sworn to before 

a judge or a clerk of a court of record or a United States attorney, who must certify 

of his own personal knowledge that the sureties are sufficient to pay the full penalty 

of the bond.

If the estimated amount involved in the contract does not exceed the sum of $200, 

then the bond may be waived.

BESERVATIONS.

The right is reserved to the head of each department or independent establishment 

to reject any and all bids, to waive technical defects, and to accept any part of any bid 

and reject the other part if in his judgment the interests of the Government shall require 

it; also the right to annul any contract, if in his opinion there shall be a failure at any 

time to perform faithfully any of its stipulations, or in case of a willful attempt to 

impose upon the Government coal inferior to that required by the contract; and 

any action taken by the head of any department or independent establishment in pursuance of this latter stipulation shall not affect or impair any right or claim of the 

United States to damages for the breach of any of the covenants of the contract by the 

contractor. 

The quantity of coal is based upon the previous annual consumption, but the right 

is reserved to order a greater or less quantity, subject to the actual requirements of the 

service.

The right is reserved to award the contract at a price higher than that named in 

lower bid or bids, the award to be based on the quality of the coal offered.

The right to reject any or all bids and to waive defects is expressly reserved by the 

Government.

DELIVERY.

The coal shall be delivered in such quantities and at such times as the Government 

may direct, deliveries to be made to any point, or points, within the District of Columbia as designated in the order.

The contractor will be allowed to deliver coal during the usual hours of teaming, or 

between 8 a. m. and dark.

For prompt settlement of accounts it is imperative that contractors shall notify the 

coal-inspection section of the United States Geological Survey during office hours on 

the day before deliveries are to be made that such deliveries are contemplated.

The coal will be weighed by representatives of the Government without expense to

the contractor, as required by the act of March 2, 1895.

All charges for transportation and cartage must be prepaid by the contractor.

The available storage capacity of the coal bunkers will be placed at the disposal of 

the contractor to facilitate delivery of coal under favorable conditions. Information 

is furnished in the schedule herewith in relation to the several places at which the 

coal should be delivered, and the bidder is invited to visit those places and inspect 

the conditions.

After verbal or written notice has been given to deliver coal under this contract, a 

further notice may be served in writing upon the contractor to make delivery of the 

coal so ordered within twenty-four hours after receipt of said second notice. Should 

the contractor, for any reason, fail to comply with the second request, the Government will be at liberty to buy coal in the open market, and to charge against the 

contractor any excess in price of coal so purchased over the contract price.

SAMPLING.

As payment is based on the quality of the coal delivered as shown by analyses of 

representative samples, it is imperative that samples representing every order for 

coal shall be taken, and it shall be the duty of the proper officials of the government
THE GOVERNMENT AS A COAL CONSUMER. 37

buildings at which coal is delivered to see that such samples are taken. The coalinspection section of the United States Geological Survey will have general supervision of such sampling, giving instructions in the methods of taking representative 

samples and lending all possible assistance.

If practicable, the coal will be sampled when it is being delivered at the building. 

For small deliveries it may be necessary to take samples from the yards or bins. The 

sample'taken should not be less than 100 pounds, to be selected proportionately from 

tffe lumps and fine coal, in order that it may in every respect truly represent the 

quality of the coal delivered.

In order to minimize the loss in the original moisture content and to obtain a uniform sample the gross sample will be pulverized as rapidly as possible until none of 

the fragments exceed one-half inch in diameter. The fine coal will then be mixed 

thoroughly and divided into four equal parts. Opposite quarters will be thrown out, 

and the remaining portions thoroughly mixed and again quartered, opposite quarters 

being thrown out as before. This process will be continued as rapidly as possible 

until the final sample thus obtained can be contained in a 2-pound can or jar and 

sealed air-tight.

The sample will then be forwarded to the chemical laboratory.

If desired by the coal contractor, permission will be given to him, or his representative, to be present and witness the quartering and preparation of the final sample to 

be forwarded to the government laboratories.

Immediately on receipt of the sample, it will be analyzed and tested by the method 

adopted by the American Chemical Society, and by the use of a bomb calorimeter. 

A copy of the result will be mailed to the contractor on the completion of the analysis

and test.

ANTHRACITE COAL.

CHARACTER OF COAL.

Bids are desired on coal, 2,240 pounds to the ton, of the kinds and sizes shown in 

Table 3. To receive consideration bids must be based on the percentages of ash 

shown for the various classes of coal.0

These coals may be delivered from the car without being screened, but must be 

reasonably free from dust and fine coal.

Coal with less ash than the standard will be paid for at a higher price, and vice versa, 

in accordance with the provisions for payment.

a The economic value of a fuel is affected by the actual amount of combustible matter it contains, as 

determined by its heating value shown in British thermal units per pound of fuel, and also by other factors, 

among which is its ash content. The ash content not only lowers the heating value and decreases the 

capacity of the furnace, but also materially increases the cost of handling the coal, the labor of firing, the 

cost of the removal of ashes, etc.

BITUMINOUS COAL. 

CHARACTER or COAL.

Bids are desired on coal, 2,240 pounds to the ton, described as follows: 

To meet the special requirements the coal will be designated as a good steam, coking, 

run-of-mine, or forge bituminous coal, 'free from dirt and excessive dust, and adapted 

for successful use in the particular furnace equipment for which the coal is desired. 

The foregoing information will be furnished by the Government as may be determined 

by boiler and furnace equipment, operating conditions, and the local"market. The 

Government expressly reserves the right to have a practical service test made by the

a Payment for anthracite coal purchased on the double standard of ash iii "dry coal" and British thermal units in coal "as received " is made on the same basis as for bituminous coal (p. 39).
THE GOVERNMENT AS A COAL CONSUMER. 39

United States Geological Survey, the results to determine the final award of contract. 

The interested bidder or his authorized representative may be present at such test.

Coals containing ash in excess of 10 per cent, volatile matter in excess of 22 per cent, 

or sulphur in excess of 2.5 per cent, as shown by analyses of samples representing dry

coal, will not be considered.

CAUSES FOB REJECTION.

A contract entered into under the terms of these specifications shall not be binding 

if, as the result of a practical service test of reasonable duration, the coal fails to give 

satisfactory results, due to its noncoking character, to excessive clinkering, to a 

prohibited amount of smoke, or to any other cause or causes which make it an undesirable fuel.

It is understood that the coal delivered during the year will be of the character 

specified by the contractor. It should therefore be supplied, if possible, from the 

same mine or group of mines.

Coal containing percentage's of volatile matter and sulphur higher than the limits 

indicated herein and coal containing a percentage of ash in excess of the maximum 

limits indicated in the following table will be subject to rejection.

Payment for coal which has been delivered and used for trial or which has been consumed or remains on the premises at the time its quality is determined will be made 

at a price computed under the terms of these specifications.

Occasional deliveries of coal containing ash up to the percentage indicated in the 

column headed "Maximum limit for ash" may be accepted. Frequent or continued 

failure to maintain the standard established by the contractor, however, will be considered sufficient cause for cancellation of the contract.

PRICE AND PAYMENT.

On certification from the coal-inspection section of the United States Geological 

Survey that samples have been procured from deliveries constituting a completed 

order, payment will be made at once of 90 per cent of the amount of the bill, 10 percent being withheld to protect the Government against the delivery of coal of inferior 

quality and to offset any deduction that may be determined by the United States 

Geological Survey from the average quality of all the deliveries on the order. On 

receipt of the Survey's report on the quality of the coal final settlement will be made.

If the 10 per cent withheld should prove insufficient to satisfy the claim of the Government on account of the delivery of fuel of low grade, the balance shall be deducted 

from the next succeeding order or orders.

Payment will be made at the price named in the proposal for the coal specified 

therein, corrected for variations in heating value and ash, as shown by analysis, above 

and below the standard established by the contractor in his proposal.

The correction in price for variations in British thermal units is a pro rata one and 

is determined by the following formula:

Delivered B. t. u. . .

Standard B. t. u. Xcontract Price=pnce to be paid.

For example, if a coal delivered on a contract guaranteeing 14,000 B. t. u. in coal 

"as received" at a price of $3 per ton shows by calorific test 14,300 B. t. u. in coal 

"as received," the price to be paid is found, by substitution in the formula, to be

-

The price will also be further corrected for the percentage of ash. For all coal which 

by analysis contains less ash than that established in this proposal a premium of 1 

cent« per ton for each whole per cent less ash will be paid. An increase in the ash content of 2 per cent over the standard established by contractor will be tolerated without

ln the specifications for the fiscal year 1910-11 this premium will be 2 cents.

exacting a penalty for excess of ash. When such excess exceeds 2 per cent above the 

standard established, deductions will be made from the price paid per ton in accordance with Table 5.

It is important that the standards furnished with bids do not establish a higher value 

than can be maintained under the terms of the contract. In this connection it should 

be noted that the small mine samples as usually taken indicate a higher economic 

value than that of the coal delivered in carload lots, owing to the greater care exercised 

in separating extraneous matter from the coal of the mine sample. It is therefore 

evident that it will be to the interest of the contractor to furnish a correct description 

of the coal offered and an accurate statement of its actual value, as a failure to maintain 

the standard fixed by him will result in deductions from the contract price and may 

cause a cancellation of the contract, while coal of higher grade than that stated will be 

paid for at an increased price per ton.

SCHEDULE OF COAL REQUIRED BY THE EXECUTIVE DEPARTMENTS AND INDEPENDENT 

ESTABLISHMENTS OF THE GOVERNMENT FOR THE FISCAL YEAR ENDING JUNE 30, 19 .

[Here follows in tabulated form a list showing the departments or offices and places 

of delivery, the capacities and facilities for stowage, and the estimated amounts and 

kinds of coal required. The bidders are requested to furnish with each bid the commercial name of the coal they propose to deliver; the name and location of the mine 

or mines; the name or other designation of the coal bed or beds, and the price of coal 

offered per ton; and for bituminous coal (and also for anthracite when purchased on 

the double standard) the percentage of ash in "dry coal" and the calorific value in 

British thermal units of the coal "as received." These values become a part of the 

contract and constitute the standard according to which payment is made.]

ANALYSES AND RESULTS FOR THE FISCAL YEAR 1908-9. 

AVERAGE QUALITY OF ANTHRACITE.

Not all of the anthracite coal purchased by the Government is paid 

for on the basis of ash values fixed by the Government; some of the 

contracts are made under specifications similar to those used for 

bituminous coal, which permit the bidder to establish the quality of the 

coal. In Washington, where the method of payment according to ash 

content as shown by analysis has been practiced, it is thought that the 

Government may at some time adopt exclusively the method that 

permits the bidder to establish the standards.

Table 7 shows the general average of moisture,, heating value, 

volatile matter, and ash in the several sizes of anthracite coal delivered in Washington for the fiscal years 1907, 1908, and 1909.

DETAILS OF ANALYSES.

Table 8 gives the analyses of coal delivered during the fiscal year 

1908-9, showing the results of purchasing coal under specifications.

The name of the city, the place of delivery, the description of the 

coal furnished, the estimated year's supply, the contract price per 

ton, and the standards of quality guaranteed are fully set forth at the 

head of each subdivision of the table. In the statement of the 

standards of quality percentage of ash is understood to refer to dry 

coal and B. t. u. to coal as received. The kind of coal referred to is 

bituminous except as otherwise stated, and the ton used is that of

average analysis. .

To give a general idea of the quality of the coal delivered during the

values will be noted, both as to penalty and as to bonus; but these 

departures so balance one another that the general average of results 

closely approximates that of the standards specified. This statement is true not only of monthly averages, but of averages covering 

longer periods.
