There are two veins, with stratum Of soap.
stone between. The upper vein is ten feet
and the lower six feet in thickness, The
coal is used principally for domestic purposes,
fifteen thousand tons having been sold in
Omaha the past year.
The Vandyke mine, forty miles west of
HallviIle, was discovered in 1854 by an old
mountaineer, who sold his claim in 1859 to
the Hallville Company for $4,000 The
coal is used mainly for steam and black
smIthing purposes. Eighty thousand tons
were sold in Omaha he past year, and the
remainder was sent ell over the western ter
ritories for manufacturing purposes.
The carbon mines, which were recently
burned, are on the railroad, one hundred
and forty miles west Of Cheyenne. The
coal is reached by perpendicular shaft
seveaty feet in dPrh. Inc vein is six "a
nine feet. Before the explosion itIwas pro-
ducing three ,I1s.hdIcd tons per day, and
was supplying The Union Pacific and the
Denver dvisiOn OF the Kansas Pacific Rail
road
The Rock Spring mine, SI5 miles west
Of Cheyenne, is an eight foot vein reach ID
by an OPsadri(t ID the side of the hill. The
product during 1870 was about two thous.
aud tons per month. During December
there were taking out and shipped nearly
2, 900 'tO6s
ExplofatiOns lately made show that the
coal measures Of Wyoming cover a very
large ARA, aad IdOHJ Of the best veins have
not yet been worked. The Ignite deposits
Of the Laramie plains, in bells from five to
eleven feet thick, have been traced ten
miles cast of Roch Greek, branch OF Mcdi-
cine Bow River, aud outcroppings occur
along the north Platte, Muddy Creek, Bit
ter Creek, Echo Canon, Weber river and
west Us lar a. the borders Of Utah. The
same deposits have been found eighty miles
above 1T. Laramie. Tie whole product -ot
the y yeassDg coal sssises ls tssw about 20
900 tons per month. The increasing de-
mand for coal both inr domestic purposes
and Tor Uanufacturers, must increase the
product this year to more than double its
present amount. The capacity If al the
banks on the Inc of the Union Pacific can
be multiplied many fold, aud tho supply
seems incXhau>tihlc. Prof HAYDEN, United
States geolOgist, who few years ago com
pleted bis examination Of the mineral re-
sources Of Wyoming, gives it as his opinion
that in general heating properties, in free
dom from sulphur, and in impressive resist
ance to atmospheric influence, Evanston
coal will compare favorably with any in the
market. Il will make moro steam than the
same quantity Of anthracite, and IS better
for gas generation than Pittsburgh coal. It
has less waste, showing smaller proper
ton Of ashes aud cliukcrs. Experiments
made in manufactures at Omaha show that
it excels Lehigh coal for smelling, as it adds
to the grain and toughucss Of the metal.
From tests made in the motive department
of the Union Pacific road it is found that a
ton Of Wyoming coal will propcl an engine
seventy-tive miles, while the reports Of the
Pennsylvania Central show that ton Of
anthracite will run an engine but forty
miles.
