It is a significant fact that shortly afterwards these two officials purchased a large mill and other property at a cost of ten thousand pounds, and that the mine yielded for the following three years during which I was connected with it an average of over 17 dwt. to the ton, as against formerly 10 to 12 dwt. "The reader must draw his own conclusions.
Thus it may be that a mine carrying 5 or 6 oz. of gold to the ton but badly circumstanced as to distance, mountainous roads, lack of wood and water, in some cases a plethora of the latter, or irregularly faulted country, may be less profitable than another showing only 5 or 6 dwt., but favourably situated.
The taste of our countrymen will require, that their furniture plate should be as good as the British standard. Taste cannot be controlled by law. Let it then give the law, in a point which is indifferent to a certain degree. Let the Legislatures fix the alloy of furniture plate at 18 dwt., the British standard, and Congress that of their coin at one ounce in the pound, the French standard.
It was agreed that I should not be judged by the novelty of my invention, but by the results which I promised, namely, of being able to deposit with a smooth surface 30 dwt. of silver upon a dish-cover, the crystalline structure of the deposit having theretofore been a source of difficulty.
There Moses speaks of "the land of Havilah, where there is gold"; and in Genesis, chapter xxiv., we read that Abraham's servant gave Rebekah an earring of half a shekel weight, say 5 dwt. 13 grs., and "two bracelets of ten shekels weight," or about 4 1/2 ozs.
Man repented with scourges, prayed by bead, bribed the saints with wax tapers, put fish into the body to sanctify the soul, sojourned in cold water for empire over the emotions, and thanked God for returning health in 1 cwt. 2 stone 7 lb 3 oz. 1 dwt. of bread and cheese.
They weigh 212 oz. 27 dwt., which is about L50, at 5s. per oz., and then they judge the fashion to be worth above 5s. per oz. more nay, some say 10s. an ounce the fashion. But I do not believe, but yet am sorry to see that the fashion is worth so much, and the silver come to no more. So home and to my office, where very busy late.
Thus 1 grain to the pound, 2240 lbs. to the ton, would show that the stuff contained 4 oz. 13 dwt. 8 gr. per ton. Retort as before described. This device is my own invention. The only genuine test after all is the battery, and that, owing to various causes, is often by no means satisfactory.
The silver coin assayed by Sir Isaac Newton, varied from 1 1/2 to 76 pennyweights alloy, in the pound troy of mixed metal. The British standard has 18 dwt.; the Spanish coins assayed by Sir Isaac Newton, have from 18 to 19 1/2 dwt.; the new French crown has in fact 19 1/2, though by edict it should have 20 dwt., that is 1/12.
Oro and Gildenstein, the celebrated assayers, have found that a sample of rock from the Golden Mint Mine, Golconda, assays at the rate of 2,546 oz. 13 dwt. and 21 gr. to the ton, and that there are thousands of tons of similar stone in sight, the statement should be received with due caution. The assay is doubtless correct, but the deductions therefrom are most misleading.
