This vast work will absorb many years, and millions of dollars, in its completion; but it will early yield money, for that desirable epoch will begin as soon as it strikes the first end of the vein.

The tunnel will be some eight miles long, and will develop astonishing riches.

Cars will carry the ore through the tunnel and dump it in the mills and thus do away with the present costly system of double handling and transportation by mule teams.

The water from the tunnel will furnish the motive power for the mills.

Mr.Sutro, the originator of this prodigious enterprise, is one of the few men in the world who is gifted with the pluck and perseverance necessary to follow up and hound such an undertaking to its completion.
