million dollars with great regularity from

possibilities for the future. The sensa

1890 increased the output from an ay-
erage of four millions year to nearly
twenty-nine millions. which was high

The experts say that 'the future of
Cripple Creek is largely dependent upon
the character of the veins below the
present tunnel level. 1t is believed that
the depOSitS will be less rich at greater
depths but the tunnel is likely to open
many important ore bodies and its com
pletion should be followed by an Increase
in the output. which may be maintained
for many years. But 1t should De re-
membered that we know little about the
conditions or the size of the ore shoots
below the bottoms of the present shafts
BaSing an opinion as to the output OF the
future simply on the records OF the past
one may say that the state will probably
be able to maintain production of SO.

will increase rather than decrease IN the 1

Nevada is the sensational state. and
its gold harvest has been very irregular,
fat years being followed by lean ana
bonanzas being followed by exhausted
veins The discoveries at Tonopah and
Goldfeld brought the state into proml-
nence after several years of indlner-
ence and increased the annual harvest
from about four millions to fifteen in
1907. That was hgh-water mark, and
the total fell back to $11 ,6S9.4U in 1908.
The state has been thoroughly pros
pected during the last eight or ten years,
and it is not likely that there will be
any sensational discoveries in the fu-
ture. But according to the experts, Ne
