"By a comparatively recent up

has been forced up through the secon-

In 1880 lie wrote of the country north
of Ruby:
Five miles due north from
Ruby camp on the main range at the
head of Poverty basin, the porphyry
again makes Its appearance, stretching
out along the summit of the mountains.
Here there are some very fine pros
poets and many locations have been
made. Some very strong and we'll
defined veins, carrying antlmonlous
silver ores crop out and are traccablc
along the surface for several hundred
feet in some places. At a few feet
below the surface ruby Silver has been

This is sufficient, all this was seen
and said in 1850 and January, 1881.

In fact there is nothing after all in
this Ruby Mining District in Septem-
Der 1881, where, according to the
same authority, there was only about
eight months before the most fatter-

ores, contact iissnre veins and por-
phyry in profusion, and "the main
