Behold him, then, a few weeks after this conversation, secretly hand and glove with Captain Ablewhite, going occasionally to the Captain's rooms and picking up a few sovereigns; going occasionally to a race-course and coming home a pound or two the richer, and night after night covering pages upon pages with figures and calculations from racing-books. He was very cautious in these gambling transactions, and he suffered tortures upon nearly every occasion when he sat down in Miser Farebrother's office, which he regarded as his own, and reckoned up what he might have won had he been able to screw his courage to the sticking-point. "Had I done this or that," he thought, "had I had pluck, I should have been so much in pocket. The Captain told me I should require pluck now and then, and that the result would be a certainty--and it would have been." At the end of some three months, during which he was feeling his way, he calculated that a little courage would have made him the richer at least by a couple of thousand pounds--for, as is the case with every person who calculates after the event--he had no doubt that he would have backed such or such a horse or such and such a jockey, or have adopted such or such a combination, the issue of which would have been to put him on the straight, or the crooked, road to fortune. At length he was convinced that he had discovered a certain system of winning. What that system was it would be imprudent to explain here, for the reason that it might lead misguided persons to ruin. Sufficient that Jeremiah was convinced that it was impossible of failure, and that he had very nearly nerved himself to plunge boldly into it. Meanwhile the fever and the infatuation of betting and gambling had taken such complete possession of him that he thought of little else, except the safety which lay in his marriage with Phoebe. "For," as he argued with himself, "supposing that by some extraordinary combination of circumstances luck should go against me, I should still be all right if I were the master of Miser Farebrother's business, and if his money were mine." As for anything in shape of sentiment, that was entirely outside his domain; his nature was not capable of it. He thought only of himself, and worked and schemed only for himself.
