He kept his box and cards in a closet adjoining his room. One night during his absence I fitted a key to his closet, took out his cards, and sand-papered the face of eight cards in each deck. I then removed the top of his faro-box, bulged out the centre of the front plate at the mouth, and filed the plate on the inside at both corners to a bevel. I then replaced the top, put in a deck of cards, and made a deal. I found the cards not sanded would follow up and fill the mouth of the box after each turn was made; and if the mouth remained dark and the edge of the top card could not be seen, one of the sand-papered cards was next, and a loser. This would give me several "dead" turns in each deal. By this means the great man, still despised as a Boston bean-eater, was able to bring his adversary to ruin. The adversary at last discovered the artifice, and "for the next five years," to quote Moore's own words, "we met as strangers." It will be seen that from his earliest days Moore possessed a scientific ingenuity, which the hard experience of life rapidly improved. And it was not long before a definite direction was given to his talent. Arrested in 1856, as he thought unjustly, he determined "to do no more work until obliged to do it for the State." He therefore turned his skill of hand to account, and went into the "green goods business." His success in this venture was so great that he made the best dollar bills ever put upon the market, and he boasts legitimately that in the game he "never lost a man." Presently he discovered that there was a quicker profit in stolen bonds. "From my first venture in this bond-smashing business," to quote his own simple words, "in 1862 up to 1870, I made more money than in any branch of industry I was ever engaged in." "Branch of industry" is admirable, and proves that Moore had a proper appreciation of his craft. But bond-smashing compelled a perfect knowledge of locks and bolts, and in this knowledge, as has been said, Moore was supreme. At the end of his career, when he had hung his arms upon the wall, and retired to spend a green old age at Boston, it was to his treatment of Yale and Lillie locks that he looked back with the greatest pleasure. But no exploit flattered his vanity more easily than the carrying off from the Bank at Concord--the Concord of Emerson and Hawthorne--of some three hundred thousand dollars. That he purchased his freedom by an ample restitution mattered nothing to the artist. His purpose was achieved, his victory won, and if his victims came by their own again, he at least had the satisfaction which comes of a successful engagement.
