10. Bullfrog district, described in this
report lies sixty miles south southeast

ihoss mine Is said to have shipped about
ll9 tons OF rich ore, the original Bull
frog about l3 tons and the Denver at

fhiHed 1000 sacks. AS all ore at the
lns the survey members visited the dis
met had 10 be hauled by wagons TO Gold
ed or Las Vegas, the general tendency
Gorg the mine owners was 10 delay
