To quickly assess the difficulty of the text, read a short excerpt:
Irfto never have found any on yit, or irho hr, run out of it. They are tired of paying assessments, and their mines will probably not bo prospected for many years to come. This drain tunnel will enable them to explore their claims at a g: depth, atjout a small expense : ;ni.. L tin-re is every reason to think that many of them will prove of great value.
19 GREAT DEPTH WHICH WILL BE ATTAINED HERE AFTER.
The mines can be worked a great depth below the level of this tunnel by pumping the water int...o the same. This is accom- plished in Europe, in a very ingenious manner, at comparatively small expense, by collecting the water in the upper parts of the mine in reservoirs and conducting it in pipes to hydraulic engines placed at the level of the tunnel ; thus using a portion of the wry water which causes all the obstacles at present, as a most useful and economical motive power to propel pumps ; which, in their turn raise the wafer from great depths below. It may safely be stated, therefore, that by means of this tunnel the Comstock ledge can profitably be worked to a depth of at least 3, 000 feet.
