Excerpt from book: DIAGRAMS OF THE MINES ON THE COMSTOCK LODE. During last winter, Mr. King was engaged several weeks in making a careful and thorough survey of the mines on the Comstock Ledge.

These diagrams, it is expected, will be lithographed at Washington, and Mr. King has promised me a full set for the State of Nevada.

It is well ventilated, and is easy of access. There are large quantities of ore in sight, not assorted, and which will yield a profit of from $6 to $8 per ton in gold and silver. There are both chlorides and sulphurets of silver. The gold is invisible in the ore. The east wall has a lining of clay from four to twelve feet in thickness. There are indications that this mine will increase in value at greater depths. It is being opened by a lower tunnel, which will show its character at the depth of about six hundred feet.
