The Sutro tunnel is once more q mat
ter Of absorbing interest to . large num-
Der Of the mines along this portion Of
the Coms,ock. and the subject Of con-
nections with il 10 agitating the mining
populace anew. The connection about
10 DO made by the Jacket is the central
point around which much Of the above.
m.ntioned interest centers.
The south header Of the tunnel 10 now
in Con. Imperial ground. aud the dis
lance to the Jacket shaft does not vary
much from 1900 feet. The Con. Iup--
rial has 463 feet. the Challenge 30. the
Confidence $50, and the jacket to the
sbai, as per survey GOO feet. This will
make a total OF 1888 feet. The header
does not move squarely across the mines
but the Jacket will make its connection
a, least 50 feet further north than where
the surveyed point lies; hence the diner
epce in the distance 10 run. This. with
the distance in Imperial will bring the
total to about 1900 feet on the line run,
From the point where the Jacket will
connect with the south lateral branch OF

was to connect by the survey. that lat
