RESULTS OF SPIRIT LEVELING IN ILLINOIS,

1909 AND 1910.

R. B. MARSHALL, Chief Geographer.

INTRODUCTION.

Previous publication. The following results of spirit leveling are 

supplemental to and accord with the elevations contained in Bulletin" 

421, and are in agreement with the 1907 adjustment of precise leveling by the Coast and Geodetic Survey. Corrections to Bulletin 421 

should be noted as follows:

Page 9: Bloomington, at Chicago & Alton junction (Kansas City division);

top of rail. Elevation should be 775.9. 

Page 10: Mahomet, 2 miles west of. Should be " east of." 

Page 46: Belleville, northeast corner of courthouse yard; iron post stamped

"Prim. Trav. Sta. No. 15, ADJ 531." The elevation of this should now

be 529.411. 

The quadrangle names Russellville and Saidora have been changed, and the

new names, Birds and Chandlerville, respectively, appear in this bulletin. 

The following quadrangle names have also been changed, but do not appear in 

this bulletin:

Apple River to Elizabeth.

Dawson to Cornland.

Farmer City to Arrowsmith.

Nashville to Hoyleton.

Oakland to Ashmore.

St. Charles to Geneva.

Shirley to McLean.

Sidell to Hunie.

Windsor to Stewardson.

Personnel. The field work of 1909 ajid 1910 was done under the 

supervision of W. H. Herron, geographer, under the general direction of R. B. Marshall, chief geographer. Credit is given to the different levelmen in the introduction to each list. The office work of 

computation, adjustment, and preparation of lists was done mainly 

by S. S. Gannett, geographer, under the general direction of E. M. 

Douglas, geographer.

Classification. The elevations are classified as precise or primary, 

according to the methods employed in their determination. For precise-level lines instruments and rods of the highest grade are used, 

each line is run both forward and backward, and every precaution is 

taken, to guard against error. The allowable divergence between the 

forward and the backward lines in feet is represented by the formula

5
6 SPIEIT LEVELING IN ILLINOIS, 1909 AND 1910.

0.017 VD> in which D is the distance in miles between bench marks. 

For primary lines standard Y levels are used; lines are run in circuits or are closed on precise lines, with an allowable closing error 

in feet represented by 0.05 VD, in which D is the length of the circuit 

in miles, sufficient care being given to the work to maintain this standard. For leveling of both classes careful office adjustments are made, 

the small outstanding errors being distributed over the lines.

Bench- marks. The standard bench marks are of two forms. The 

first form is a circular bronze or aluminum tablet (G and E, PL I), 

3£ inches in diameter and \ inch thick, having a 3-inch stem, which 

is cemented in a drill hole in solid rock in the wall of some public 

building, a bridge abutment, or other substantial masonry structure. 

The second form (F, PI. I), used where masonry or rock is not available, consists of a hollow wrought-iron post 3^ inches in outer diameter and 4 feet in length. The bottom is spread out to a width of 10 

inches in order to give a firm bearing on the earth. A bronze or 

aluminum-bronze cap is riveted over the top of the post which is set 

about 3 feet in the ground. A third style of bench mark, with abbreviated lettering (B and Z>, PI. I), is used for unimportant points. 

This consists of a special copper nail 1£ inches in length driven 

through a copper washer $ inch in diameter. The tablets as well as 

the caps on the iron posts are appropriately lettered, and cooperation 

by States is indicated by the addition of the State name (#, PL I).

The numbers stamped on the bench marks described in the following pages represent the elevations to the nearest foot as determined 

by the levelman. These numbers are stamped with ^-inch steel dies 

on the tablets or post caps, to the left of the word " Feet." The office 

adjustment of the notes and the reduction to mean sea level datum 

may so change some of the figures that the original markings are 1 

or 2 feet in error. It is assumed that engineers and others who have 

occasion to use the bench-mark elevations will apply to the Director of 

the United States Geological Survey, at Washington, D. C., for the 

adjusted values, and will use the markings as identification numbers 

only.

Datum. All United States Geological Survey elevations are referred to mean sea level, which is the" level that the sea would assume 

if the influence of winds and tides were eliminated. This level is not 

the elevation determined from the mean of the highest and the 

lowest tides, nor is it the half sum of the mean of all the high tides 

and the mean of all the low tides, which is called the half-tide level. 

Mean sea level is the average height of the water, all stages of the 

tide being considered. It is determined from observations made by 

means of tidal gages placed at stations where local conditions, such 

as long, narrow bays, rivers, and like features, will not affect the 

height of the water. To obtain even approximately correct results 

these observations must extend over at least one lunar month, and
INTRODUCTION.

if accuracy is desired they must extend over several years. A.t ocean 

stations the half-tide level and the mean sea level usually differ 

but little. It is assumed that there is no difference between the mean 

sea level as determined from observations in the Atlantic Ocean, 

the Gulf of Mexico, or the Pacific Ocean.

The connection with tidal stations for bench marks in certain 

areas that lie at some distance from the seacoast is still uncertain, 

and this fact is indicated by the addition of a letter or word to the 

right of the word " Datum " on tablets or posts. For such areas 

corrections for published results will be maole from time to time as 

the precise-level lines of the United States Geological Survey or 

other Government organizations are extended.

Topographic maps. Maps of the following quadrangles, wholly or 

partly in Illinois, have been published by the United States Geological Survey up to June IT, 1911. They may be obtained, unless otherwise noted, at 5 cents each or $3 a hundred on application to the

The following descriptions and elevations of bench marks from St. 

Louis, Mo., to Cairo, 111., are taken from a report by the Special 

Board of Engineers on Survey of the Mississippi River, from St. 

Louis to its mouth (61st Cong., 1st sess., House Doc. No. 50), and 

the descriptions and elevations of bench marks from Menominee, 111., 

to St. Louis, Mo., from a report of the Mississippi River Commission, 

published at St. Louis, Mo., in 1899. They are republished by permission of the Chief of Engineers, United States Army. The elevations in the reports mentioned above are referred to the Memphis 

datum plane, but corrections, ranging from 6.82 feet near Cairo to 

 6.67 feet near Menominee, have been applied to refer them to mean 

sea level, according to the 1907 adjustment of the Coast and Geodetic 

Survey.

The lines of bench marks called stone lines are placed normal to 

the river at intervals of about 3 miles and are numbered consecutively 

from Cairo northward. Each stone line generally consists of four 

bench marks, two on each side of the river, the one farthest from the 

river on the left (east) bank being No. 1.

The elevations of the stone-line bench marks were determined by 

the ordinary leveling of the topographical party, running from the 

adjacent precise level bench marks. The discrepancy between the 

precise and ordinary leveling, between successive precise level bench 

marks, has averaged about 0.06 foot. 

82
ELEVATIONS BY MISSISSIPPI RIVER COMMISSION. 83

The bench marks above Alton, 111., consist of a flat tile 4 inches 

thick and 18 inches square, with a copper bolt leaded vertically into 

the upper face at the center. The tile is set about 3 feet below the 

surface of the.ground and is surmounted with a 4-inch iron post 4 feet 

long, upon which an iron cap is bolted. All the bench marks used 

since 1891 are of this form, distinguishing symbols being sunk into 

the tile and raised on the iron cap. A triangle (A) indicates a 

secondary station, a circle (O) a precise level bench, and a square 

(D) a stone-line bench. The words " Mississippi River Commission " 

and letters " U. S." are printed on both tile and cap.

The stone-line bench marks below Alton are similar except that 

they have flat stones in place of tiles, and are surmounted by iron posts 

5.1 feet long. The earlier triangulation marks were usually stone 

posts about 3 feet long, set 30 inches in ground, the top ends being 

dressed to about 6 inches square, and some of the earlier stone-line 

bench marks were also of this type. Where standard bench marks 

are not used, descriptions of the marks employed are given. The 

numbers of Mississippi River Commission bench marks are given in 

parentheses and refer to the surface mark.
