point a distance Of 1900 feet vertically
from the tunnel level. To the northeast
it extends to and joins onto the Emma,
the Flagstaff the Toledo and the VaIeo.

A Fortunate Find.
A recent acquisition is the Rowland
group from which, in former days,
some $4,000 were taken from surface
workings until water level wac reached.
Later some 1.200 feet of work was done
IN tunnels and drift on the same level
as the Columbus tunnel. but this pro-
duced no substantial results. When
the Columbus people resumed work in
this property, a development occurred

that are encountered IN mining and
