The hard variety OF "asbestOs" in or1r,erIa ra or
chrysoltc occurs in many localities, but none Of if is vet mined
for commercial use. The softer and finer quality, chrvsotle,

Icenent length and wonderful quality for spinning or anv of the
finer uses Of the mineral. The United States Asbestos Mining
ments for a large territory on Casper Mountain. and has done
some work preparatory to development work and erection of a
mill next spring. Negotiations have also been opened for a mill
on the Smith Creek at the same time and the active production OF
asbestos rock should begin early in the summer. 1t is more than
probable that the first mills will be devoted simply.t6 making
coarse grades by removing Just enough Of the enclosing SER
pentine rock to make a profitable shipping grade for the rougher
purposes OF asbestos, but later the works will be enlarged and
he finer grades of product manufactured.
There is a small plant producing sulphur at Cody, in Big

Building stone is quarried and made for local use and two
government buildings and in active competition with stones from
other states. These are at Rawlins, in Carbon County, and at

and nearly every one of the best known building stones from the
sottest sandstoneS to the hardest GRANTEES may be found here.
Gypsum in vast beds is found in every county in the state,
as the Triassic formations are of general occurrence along many
of the smaller uplfts and gypsum may be had almost anywhere
in any quantity.
Stucco and plasters are manufacturer at Laramie and Sher-
idan, and there are a few small local plants for local supply only.
are three mills. The two city mills, called the Acme and over
land, make dark plaster. while the Red Butte mill makes stucco
and gypsum plaster. These have a reputation all over the west
and the market is steadily improving, the production for 1907
being about 10000 tons Tor the three mills.
Portland cement materials exist here also and another year
should see a plant in operation. These materials also exist at
Iron Mountain station, Laramie County, at Newcastle. Weston
County, and Sheridan, Cody, Big Horn County, as well as a
number of other places, and with shipment matters eautably adj
justcd, the plants should pay very well on the investment.
Brick is made at Laramie, Douglas. Lander and other points
but the output is mostly used in local work.
The entire line of the Union Pacific railroad system is bal
lasted with disintegratcd granite gravel, which is taken from the
pits OF the company at Buford station, on Sherman Hill. between
Cheyenne and Laramie, and thousands of carloads are mined
annually. This Sherman gravel" as it is known, is the finest
railroad ballast yet discovered, and as the supply is unlimited,
cost Of mining is slight and there is a great field for its use in
many directions. Recently it is reported that the Rock Island
Route is securing it for their track ballast. and there is room for
Improvement on many other roadbcds in the west, as well as
gravel here to supply it.
