Taking 200 gr. of ore from a sample assaying 17 oz. fine gold per ton, grinding it finely and heating for some hours with yellow sodium sulphide on decomposing the filtrate and treating for gold I got a result at the rate of 12 oz. per ton. This was repeated several times with the same result.
This additional experience proved of great benefit to him; and he continued to prosecute his inquiries with much zeal, sometimes devoting entire nights to experiments in assaying, roasting and cementing iron-ores and ironstone, decarbonating cast-iron for steel and bar-iron, and various like operations.
After a number of attendant circumstances, too ludicrous and contemptible to relate, which befell a party, who were sent under his guidance to explore this second Peru, he at last confessed, that he had broken up an old pair of buckles, and mixed the pieces with sand and stone; and on assaying the composition, the brass was detected.
Assaying was a good business, and so some men engaged in it, occasionally, who were not strictly scientific and capable. One assayer got such rich results out of all specimens brought to him that in time he acquired almost a monopoly of the business. But like all men who achieve success, he became an object of envy and suspicion.
Paul Brennan was asked to move with caution and in utter secrecy, even to sending the reward in cash to a special post-office box. Paul Brennan's reaction was a disappointment to himself. He neither felt great relief nor the desire to exult. He found himself assaying his own calmness and wondering why he lacked emotion over this culmination of so many years of futile effort.
Aleck found himself listening to an interminable talk about copper veins and silver veins, a new kind of assaying instrument, and the good luck attendant upon the opening of Lloyd-Jones' new mine, the Liza Lu. Aleck was the essence of courtesy to everything except sham, and was able to indicate a mild interest in Mr. Lloyd-Jones' mining affairs. It was sufficient.
Then Tom and Harry, who had been putting in many spare hours, days and weeks on the study of metallurgy and the assaying of precious metals, went, for a "vacation," to Nevada, there further to pursue their studies.
And very merry and good discourse about the business we have been upon, and after dinner went to the Assay Office and there saw the manner of assaying of gold and silver, and how silver melted down with gold do part, just being put into aqua-fortis, the silver turning into water, and the gold lying whole in the very form it was put in, mixed of gold and silver, which is a miracle; and to see no silver at all but turned into water, which they can bring again into itself out of the water.
Prohack shut his eyes and gave forth vague affirmatives. And as soon as the manager had left him he gazed around the room at the too-blonde women young and old and wondered fearfully which would be his portion for bridge or dance. Then he observed the manager chatting with two haughty beldames and an aged gentleman, and they all three cast assaying glances upon Mr. Prohack, and Mr.
"Also, and above all," continued Jobson, "for I speak to your warning you, Diana Vernon, spinstress, not being a femme couverte, and being a convict popish recusant, are bound to repair to your own dwelling, and that by the nearest way, under penalty of being held felon to the king and diligently to seek for passage at common ferries, and to tarry there but one ebb and flood; and unless you can have it in such places, to walk every day into the water up to the knees, assaying to pass over."
