Not long after my arrival a prisoner gave me a young rat which became the solace of an otherwise miserable existence. Nothing could he cleaner in its habits or more affectionate in disposition than this pet member of a despised race of rodents. It passed all its leisure time in preening its fur, and after eating always most scrupulously cleaned its hands and face. It was easily taught, and in course of time it could perform many surprising feats. I made a small trapeze, the bar being a slate pencil about four inches long, which was wound with yarn and hung from strings of the same; and on this the rat would perform like an acrobat, appearing to enjoy the exercise as much as the performance always delighted me. I made a long cord out of yarn, on which it would climb exactly in the manner in which a sailor shins up a rope; and when the cord was stretched horizontally it would let its body sway under and travel along the cord, clinging by its hands and feet like a human performer. A rat's natural position when eating a piece of bread is to sit on its haunches, but I had trained this rat to stand upright on its feet, with its head up like a soldier. Placing it in front of me on the bed, I would hand it a piece of bread, which it would hold up to its mouth with its hands while standing erect. Keeping one sharp eye on me and the other on its food, the moment it noticed that I was not looking it would gradually settle down upon its haunches. When my eyes turned on it it would instantly straighten itself up like a schoolboy caught in some mischief. It always showed great jealousy of my tame mice, and I had to be very careful not to let it get a chance to get at one. On one occasion I was training one of the mice, and did not notice that the rat was near. Suddenly, like a flash, it leaped nearly two feet, seizing the mouse by the neck precisely as a tiger seizes its prey. Although I instantly snatched it away, it was too late, the one fierce bite having severed the jugular. I have mentioned mice, and indeed they were most interesting pets, easily trained and as scrupulously clean and neat as any creature of a higher race could be. I at times had a half dozen of them, which I had caught in the following simple way: I first stuck a small bit of bread on the inside of my pint tin cup, about half way down; then turning it bottom up on the floor, I raised one edge just high enough so that a mouse could enter, and let the edge of the cup rest on a splinter. It would not be long before one would enter, and as it could not reach the bread otherwise it stood up, putting its hands against the sides of the cup, thus over-balancing it, causing the cup to drop, and simple mousie would find itself also a prisoner.
