Book Description
Excerpt from On the Milling of Gold Quartz Dear sir My last paper to the State Geological Society on The Milling of Gold Quartz, wherein I tried to describe the process of simple amalgamation of the raw pyritic matter in wooden barrels, appears from the great number of letters that I have received respecting it, after its publication in the Mining and Scientific Press, to have attracted considerable attention, and has, therefore, encouraged me to resume the subject, but this time as a contribution to the State Mining Bureau; you having kindly offered to allow the specimens accompanying this paper, and intended to illustrate whati have stated, to remain for a short time at the rooms of the Mining Bureau, to give those who feel interested in the mat ter a chance of examining them. You have also promised to put some very important and interesting specimens from your private collection with them. I can only now repeat what I have stated on a former occasion, that at the present time I think scarcely anything can be of greater importance to the mining interests of this State, than a simple and cheap mode of extracting the gold from low grade veinstone, and the determination of the true condition of the ores associated with it.

Book Description
Excerpt from A Handbook of Gold Milling The process of differentiation, so essentially characteristic of all modern development, has of recent years extended very markedly into the province of the gold-miner. The time is not so long past since any ordinary miner was considered to be quite capable of taking a shift in the mill, and it was looked upon as part of his duty to be equally useful above and below ground. This state of things did well enough as long as rich reefs or rich portions of reefs, such as the superficial portions not uncommonly are, were alone worked; enough gold was won to more than pay expenses, and no one knew or even seemed to care how great the loss might be in the mill.

Book Description
Excerpt from The Stamp Milling of Gold Ores The matter thus collected is rather a painstaking description of practice than a discussion of the chemistry and mechanics of the stamp-milling process. It Will, therefore, it is believed, be serviceable to those engaged in the actual work of the mill, no less than to the student in the laboratory or lecture room.

Book Description
Excerpt from Gold Mining Districts, With Plans and Sections Hence we need not be surprised at: finding alannlanco ot' globules of mercury in the tailings of some of our mills when we witness the mode of introducing mercury. Assuming that the average yield of gold in auv parcel of quartz is one ounce to the ten, and that in a battery containing live stampers, live tons of ore are crushed in twenty-four hours, the total quan tity of mercury which should be added according to the lore going directions is six ounces, allowing one ounce and one fifth per ton. This quantity should be distributed at the rate of one quarter of an ounce per hour, or about one-twelfth of a tea spoon at a time.
