The market value of mica is great
and the present time the demand is
such that it cannot be supplied. A
piece of mica four inches by four inches,
five-eighths of an inch thick, will weigh
one pound and has a market value of
$4 A piece three by six inches, one
half of an inch thick, will weigh one
pound, and has a market value of $4.60,
and a like relative portion of value ex
ists, except in the smallest pieces, say
one-half by two inches, which have a
value of fifty cents per pound, and ail
the refuse and trimmings of the mica
are readily sold to parties who pulver
ize them for use in the manufacture of
nitro-glycerine and other dangerous ex
plosives. It will thus be seen that in
mica mining we have an industry
worthy of development, and one which
requires no expensive manipulation of
the product subsequent to excavation.
Salt Lake Tribune.
Mica in large quantities has been
found in Wyoming. Some years since
quite an excitement was created by
discoveries of this desirable article near
Cheyenne, but the trouble has always
occurred in the small*ize of the sheets
found, the cloudiness of the mica, and
other defects, which have almost in
variably made the discovery of no
commercial value. This has been the
case until very recently. The discover
ies made during the past season in the
Hartville district have been the most
promising yet made; and lying, as they
do, near valuable producing mines in
the hills, these discoveries me looked
upon as valuable prospects.
