But Pat remained immovable, so far as any confessions were concerned; and it was thought advisable, at this juncture, to call into requisition the influence of the person at whose urgent solicitation Pat had obtained his situation in the post-office. An interview between them was speedily arranged, but the accused, for a while, still continued stoutly to deny his guilt. Subsequently, however, he inquired of the post master whether, in case he produced the money, he would have his liberty. The post master assented, so far as to promise no prosecution on _his_ part, and Pat finally agreed to go with us on the following morning, and point out the place of deposit, but insisted that H., his friend and patron, (just referred to,) should be of the party. Fully impressed with the importance of securing Pat as well as the property of his victims, I now obtained a warrant, which was at once placed in the hands of one of the U. S. Deputy Marshals, who agreed to be in the immediate vicinity of the mail robber's residence, but to delay the arrest till he received a signal from me that all was ready, and after the funds were fairly in our possession. Accordingly, a hack was ordered to be at the post office at an early hour the next morning, and we (the post master, myself, Pat, and H.) were soon crossing the ferry to South Brooklyn. Ten minutes' ride brought us in front of Pat's house, where we all alighted. Here matters took a turn wholly unexpected to me, for Pat insisted that no one but his friend, H., and himself, should go for the money, which he said was buried in the yard behind the house. To this I objected, but Pat stood firm, remarking, that it would attract too much attention if all hands went, and that if his request could not be granted, he should make no further disclosures, and we might as well go back to New York. The post master and myself having at that time confidence in H., I took him aside and told him Pat must not be allowed to escape, on any account, and that if he went alone with him, he must promise to be responsible for his safe and speedy return with the money, to all of which, H. readily assented, claiming to have complete control over his man, and promising to have him back in a few moments. With this understanding they both passed round the house, and I started to give the Marshal the signal that the time for his services had arrived. Not more than three minutes had elapsed before I returned in company with that officer, and H. was seen coming towards us, with a small box under his arm, but _alone_. "Where is R.?" I inquired. "He went into the house, through the back yard," was the response. Taking the box from H., and handing it over to the post master, to be taken to the carriage, we at once passed into the house, but no Pat could be found. On applying to H., to know what this meant, he explained by saying, that as soon as the box was handed to him, Pat hopped over the fence into his back yard, and entered the house.
