MINES BUREAU DOES
MUCH FOR INDUSTRY
CONTINUED from Page ~

in many manufacturing plants, the
space in the furnace where the coal is
burned is not of sufficient size and
THAT efficient and economical burning
of the coal is impossible. This infor-
nation is to be given to the manufac-
turers of boilers, so that the designsh
may be altered to suit the new condi-
| tons
The experts of the bureau have been
endeavoring to develop the use Of
II what is known as the gas-producer,
II which burns a much lower grade Of
II coal than the steam boiler and produc-
4 es power, it is said, at less expense
Il than other methods They deplore
Il the tendency in this country toward
II the almost exclusive use of high-grade
II Goals and point to the ruthless waste
4 and neglect of low-grade fuels, which
| is in sharp contrast to the situation in
Il Europe. It is the expectation of these
4 experts to live to see the railroads of
\ the country operated by electricity
obtaining their power from gigantic
gas-producer power plants located at
| the mines.
! The bureau, i'm cooperation with the
! University of North Dakota, has been
endeavoring to give a helping hand to
the West in its rather difficult prob
lem of burning Ignite coal, of which
there are vast areas in North Dakota
and the neighboring states. The bu-
reau is aiming to develop better appli-
ances for burning the Ignite and for
/ obtaining the valuable by-products
from it,
Still lanother industry may develop
from the suggestions made by the bu-
reau as to the use of peat as fuel
and for its valuable by-products. The
bureau declares that the very exten.
sive peat beds of the United States
| contain a great and neglected source
l Of combined nitrogen, easily converts
/ bic into ammonia. which is one of the
most valuable and costly constituents
OF chemical fertilizers and is now i'm
] ported in large quantities from Euro
pean countries. The bureaus expert
on peat declares that the situation in
Minnesota, where great iron mines
/, ! are now being worked with coal sem
| more than a thousand miles, is unnec
: essary. He intimates that plant fol
q turning the peat into its by-product'
' | will pay for itself to such an extern
as to give power free to the mines.
II is pointed out that another indus
Try has been aided TO a great eXten
u 0y the devising of a new process TO
+ he making of radium from the car
> notite ores of Colorado and Utah. thu
d cost of making radium by this process
e being so low that from government
r owned ore, at least, radium can b.
applied to the hospitals Of the army
navy and public health service in tn
b | treatment of cancer at cost not eN
p feeding S36,5OO for each gram, or one
n third Of prices that had been obtaine
r by foreign dealers.
The bureau learned that while tn
e United States was either wasting o
It neglecting to use white china clay
n the South, this country was import
ing each year more than 100000
IA 1f china and porcelain and in addition
7 | a quarter of a million tons of chin
e clay which was manufactured here in
IS to various forms Of white ware. Tn
Y bureau has already notified the indus
d. try that the clay deposits of the Sout
a. are, as a rule, as good as can be OF
e tanned anywhere, some Of the clays be
n, ing remarkably white and equal
/ / quality to any imported.
At the suggestion OF the America
institute OF Metals, the bureau wen
70 to the aid of brass manufacturers an
n. undertook a study of the relative e
10 Iiciency of the various furnaces in o
r. der to stop a loss Of more than $4,000
e 600 a year The bureau lately puI
Iy ushed a bulletin which has becom
ID an almost universally used handboo
I among the brass founders and is r
5ulting i'm greater efficiency and
1 ! the prevention OF metal losses
The bureau makes the statemel
NJ that many brass founders have chan
e ed their methods and have applied Il
II remedies pointed out.
The marble-quarrying industry HI
-, also felt the aid of the burea
Strain breaks" resulting from roc
stresses, have caused heavy losses
many quarries, and the bureau set
bout with the cooperation OF a marb
company to study the conditions. II
| result is that a method has been d
yised of relieving the rock pressu
so as to prevent destructive fractl
ing. and, as a consequence, gre
masses of valuable marble that oth'
wise would be wasted are now ut
lied.
