I can name several boys now in custody, who have been actors in some of the most complicated schemes of burglary, and from whom much on this head might be elicited. One in particular, who began his career by robbing a gentleman in Mark Lane of plate to a considerable amount; and as it shows one method of committing a robbery, I will relate how it was accomplished. The boy was under sentence of death when I got the history of his life from him, he having been nine years in the successful commission of crime; and although nearly eighteen years of age, his appearance gave him credit for only being fourteen. Whilst in custody, his constant theme of regret was that he had left the parties in whose services he had been so long and securely employed, to join some of his own age, embarking in business for themselves; by which he was "nicked" (taken up). He was an orphan, and had been brought up in the poor-house, whence he was apprenticed to a sweep in the city. He was a remarkably sharp boy, which no doubt was noticed by those who are always on the lookout for agents to aid them in their schemes. He was met one morning early, with the soot-bag on his back, by a man who pretended to be his uncle, and who gave him a half-crown piece, making another appointment for a meeting; the result of which was, before he had served sixteen months of his time he had given information by which fifteen robberies had been committed. He, of course, had been paid for his services, which soon made him disgusted with the sooty business; and he made an agreement with the man who drew him into crime, to leave his master's service, and to commit with him a robbery on their private account before he left. The house fixed on was the one above alluded to in Mark Lane. The premises had before been surveyed, and deemed impregnable; that is to say, was considered too well guarded to be robbed without detection. They, however, got possession of the plate in the following manner:--The boy was a favourite with the cook of the house, and she would have no other to sweep her kitchen-chimney; a matter of business which was performed the last Saturday in every month. It was concerted between the man and the boy, that the former should dress himself in the character of a sweep, and accompany the latter as his over-looker, or assistant. The real sweep-over-looker, of course, must be kept out of the way; and here laid all their difficulty. It cost the boy (to use his own expression) six months' longer punishment as a sweep, and the man six appearances, at an early hour of the morning, in the same character, before the object could be carried, namely, to get rid of the real sweep.
