There he besought employment of menial kinds, at the hands of the surgeons and other officers, of whom there were only a very few at the post. Again he strummed his banjo and sang his songs to good purpose, impressing everybody with the conviction that he was a jolly, thoughtless, happy-go-lucky negro, and very amusing withal. The hospital was a very small one in a very lonely part of the country, and service there was extremely tedious to those who were condemned to it. Sam's minstrelsy, therefore, was more than welcome as something that pleasantly broke the monotony, and the officers concerned were anxious to keep the amusing fellow employed at the post, lest he go elsewhere. They gave him all sorts of odd jobs to do, from blacking boots and polishing spurs and buckles, to grooming a horse when privileged in that way, to show his skill in "puttin' of a satin dress onto a good animal," as he called the process. Agatha had provided the boy with a small sum of money for use in emergencies, and, as his living had cost him nothing, he had considerably added to its amount. He cherished it jealously, feeling that it might prove to be his readiest tool in accomplishing his purposes. For a time he was not permitted to enter the hospital, which was nothing more than an old barn in which a floor had been laid and windows cut. Four sentries guarded it, one on each of its sides. The patients within numbered about fifteen, all of them wounded Confederate officers, for whom this provision had been made until such time as they should be sufficiently recovered to be taken North to a military prison. Being in no regular way employed at the post, Sam was free to go and come as he pleased, and he did a good deal of night-prowling at this time. He managed in that way to establish relations with certain of Agatha's friends, whose residence was ten or a dozen miles away. He visited them at intervals in order to hear from Agatha, and report to her through them. He had not dared inquire concerning his master in any direct way, or to reveal his interest in any of the hospital patients. But when two of them had died, he had asked one of the servitors about the place what their names were, and had thus satisfied himself that neither of them was Captain Pegram. By keeping his ears on the alert, he had learned also that there were not likely to be any further deaths, and that the remaining wounded men were slowly, but quite surely, recovering. Still further, he had heard one of the doctors, in conversation with the other, comment upon the remarkable vitality of Captain Pegram. "That wound would have killed almost any other man I ever saw, but upon my word the man is getting well. Barring accidents, I regard him now as pretty nearly out of danger."
