After the first half dozen times that Rodolphus was shut up there, he did not suffer from hunger, for he made an arrangement with another stable boy, older than himself, to supply him with food at such times. The stable boy would get bread from the house by stealth, when Rodolphus was in his prison, and bring it out to the stable in his pocket. Then, watching his opportunity, when Mr. Kerber was not looking, he would throw it over to Rodolphus. Rodolphus was thus saved from suffering much through hunger, but yet he would always in such cases, when he was finally let out, _pretend_ to be half starved, in order to prevent Mr. Kerber's suspecting that he had been stealthily supplied with food.
The prison, as Mr. Kerber called it, was adjoining the stable office, which was a very small room, partitioned off from the stable itself. This office had two doors, one on each side of it. One door led out into the stable, and was the one ordinarily used. The other led to a shed at one side of the stable, where the wood was kept for the office fire, which was made in a small stove that stood in one corner of the office. There was a desk in another corner of the office, and in this desk Mr. Kerber kept his papers and his money.
One day when Rodolphus was shut up in his prison, after having been there several hours, he became very tired of having nothing to do, and so, to amuse himself, he took his knife out from his pocket and began to cut into the partition which separated the colt-pen from the office. The partition was made of boards, and as Rodolphus's knife was pretty sharp, he could cut into it quite easily. He heard voices in the office, and he thought that if he should cut a small hole quite through the partition he could hear what the men were saying, and see what they were doing. So he cut away very diligently for half an hour, working very slowly and carefully all the time, so as not to make a noise.
At last the light began to shine through. Then Rodolphus worked more carefully than ever. He, however, soon had a small hole opened, and putting his eye close to it, he could see a whip hanging up against the opposite wall of the office. Rodolphus gradually enlarged his hole, until he could see more. He made the hole very large on the side toward his prison, and yet kept it very small toward the office, and by this means he could change the position of his eye and so see almost all over the office, without, however, having made the opening large enough to attract attention on the inside.
