Prior to his departure, Mr. Keene was urged to invest a few hundred dollars in a mining stock then selling very low. The length of his journey and the change of scene caused him almost to forget about his investment, and the methods of communication between the far West and the far East in those days were so very slow that he had hardly any chance of being informed of his lucky venture until his return. As an illustration of this slow transit of news at that time, it may be stated that gold was discovered January 19, 1848, but the news did not reach the Eastern States until the following December. It was authoritatively announced in the President’s annual message, and created great excitement. Mr. Alfred Robinson, with about twenty companions, were the first to leave New York for the scene of the new El Dorado, on the bark “John Benton.”

After nearly a year’s absence Keene was surprised to find, on his return, that mining stocks had taken a prodigious bound upward and carried the one in which he had invested with them. The mine had turned out to be a veritable bonanza, and the stock which had cost him only a few hundred dollars was then worth over $200,000.

Had Mr. Keene’s health not required his absence from the scene of speculation the chances are that he would have disposed of his stock as soon as it should have realized a few thousand dollars.

This was a wonderful realization for one who had been comparatively poor, and was sufficient to turn the head of any ordinary man; but it only made Keene more anxious for greater success, which he set himself diligently to achieve.

The speculative craze was then intense and epidemic. Waiters and chambermaids bloomed into millionaires with the rapidity of mushroom growth. Mr. Keene secured a seat in the Board, and began to do an immense business.

Flood, Mackay, Fair and O’Brien were then the prominent operators. The speculative contagion spread rapidly over the coast, and soon imparted its influence to the entire continent. Keene’s further investments were crowned with similar success to that of his first venture, and even in a greater ratio of profit.

Seeing the great and rapid advance in the stocks of the Comstock mines, he naturally reasoned, like old Daniel Drew, that what had gone up so high and so fast was bound to come down. There were but few people on the coast at that time, however, in a mood to reason so soberly, and it required more than ordinary nerve to make the experiment of selling “short.” Mr. Keene, however, had the courage of his convictions, and made an onslaught upon the market.

There Was a strong contingent to oppose him, for the wealthy syndicate just named, with the Bank of California behind them, were his bitter foes, and they did their best to crush him. In spite of their efforts, however, the market began to yield under the pressure of Keene’s “short” sales. In a little while the list gave way and stocks began to topple from their dizzy eminence, even quicker than they had climbed to that unprecedented height. Keene netted millions in their fall. He cleared two and a-half millions in the Belcher and Crown Point mines, and over half a million in Ophir.

So, in a few years, this poor lawyer, journalist, curbstone broker and invalid, found himself the happy possessor of millions, his name covered with speculative glory, and the fame of his fabulous fortune heralded in every city, town, hamlet and mining camp between the two oceans.

Keene was still found on the right side of the market when the great bubble burst, when the Bank of California went under, and its president, Mr. Ralston, committed suicide while pretending to take a bath in the Pacific Ocean.
