Abstract

Hydraulic-mining has undoubtedly its origin in America and principally in the west, when gold was found in 1848 it was imbedded in strata of clay, land and gravel, the question arose how should we get it out of the clay and etc.? and here is the origin of hydraulic-mining. First there was used the simple “pan”, then something better was found, the “cradle,” and then it came to the “tom”, “sluice” and lastly to “hydraulic mining”, all of these come under the head of hydraulic-mining, but the last which bears that name is resorted to only in situations where the pay-dirt is of great thickness, and where water is abundant; it may be regarded as the highest branch of placer mining, since by it a larger amount of dirt is washed in a given time and a less expense than by any other process. Hydraulic claims are usually situated in hilly districts, as it is not only necessary to be provided with a column of water of considerable height, but also to find in the valleys below the sluices, a receptacle for the enormous amount of “debris” resulting from the operation. I will now give in detail the aparatus used, and manner of working them, commencing with the “pan” down through “hydraulic mining.”
