In the apartment which adjoined the chamber he discovered little 'Jack the Prig,' fast asleep in bed. In the restlessness of slumber, the boy had partially thrown off the bed-clothes, and he exhibited upon his naked breast the picture of a gallows, and a man hanging! This appalling scene had been drawn with India ink, and pricked into the flesh with needles, so that it never could be effaced. It was the work of the boy's hideous father, who, not contented with training up his son to a life of crime, was anxious that he should also carry upon his person, through life, that fearful representation of a criminal's doom. 'Would it not be a deed of mercy,' thought our hero--'to take the poor boy from his unnatural parents, and train him up to a life of honesty and virtue? If I ever get the father in my power, I will look after the welfare of this unfortunate lad.' Frank left the room, and descending the stairs, began to explore the lower apartments of the house. In one, he found a large collection of tools, comprising every implement used by the villains in their depredations. There were dark lanterns, crowbars, augers, London _jimmies_, and skeleton keys, for burglary; also, spades, pickaxes, and shovels, which were probably used in robbing graves, a crime which at that period was very common in New York. A large quantity of clothing of all kinds hung upon the walls, from the broadcloth suit of the gentleman down to the squalid rags of the beggar; these garments Frank conjectured to be _disguises_, a supposition which was confirmed by the masks, false whiskers, wigs and other articles for altering the person, which were scattered about. In a small closet which communicated with this room, our hero found dies for coining, and a press for printing counterfeit bank-notes; and a table drawer, which he opened containing a quantity of false coin, several bank-note plates, and a package of counterfeit bills, which had not yet been signed. Having sufficiently examined these interesting objects, Frank passed into the next room, which was of considerable extent. It was almost completely filled with goods of various kinds, evidently the proceeds of robberies. There were overcoats, buffalo robes, ladies' cloaks and furs, silk dresses, shawls, boxes of boots and shoes, cases of dry goods, and a miscellaneous assortment of articles sufficient to furnish out a large store. The goods in that room were worth several thousands of dollars.
