It is to be observed that the promise of manumission was given as the highest bribe that could be offered to induce the slave to refund the money he had taken; for though in argument slaveholders generally maintain that their slaves have no desire for freedom, they are never known to _act_ upon that supposition. In this case, the offer served a double purpose; for it stimulated the benevolent zeal of Friend Hopper and Barney Corse, and induced the fugitive to confess what he had done. He still denied that he had any intention of stealing, but declared that he took the money merely to obtain power over his master, hoping that the promise to restore it would secure his manumission. It is impossible to tell whether he spoke truth or not; for poor Thomas had been educated in a bad school of morals. Sold by his father, abused by his brother, and for years compelled to do the bidding of gamblers and slave-speculators, how could he be expected to have very clear perceptions of right and wrong? The circumstances of the case, however, seem to render it rather probable that he really was impelled by the motive which he assigned for his conduct. Mr. Darg declared that he had previously considered him an honest and faithful servant; that he was in the habit of trusting him with the key of his trunk, and frequently sent him to it for money. The bank-bills he had purloined were placed in the hands of two colored men in New-York, because, as he said, he could not return them himself, but must necessarily employ somebody to do it for him, in the intended process of negotiating for his freedom.
