Much amused, I went at once, and he came directly in, after a long stare at me, and a few wavings of his plumy tail. It was evidently the right place, and, following me into the parlor, he perched himself on the rug, blinked at the fire, looked round the room, washed his face, and then, lying down in a comfortable sprawl, he burst into a cheerful purr, as if to say,-- "It's all right; the place suits me, and I'm going to stay." His coolness amused me very much, and his beauty made me glad to keep him. He was not a common cat, but, as we afterward discovered, a Russian puss. His fur was very long, black, and glossy as satin; his tail like a graceful plume, and his eyes as round and yellow as two little moons. His paws were very dainty, and white socks and gloves, with a neat collar and shirt-bosom, gave him the appearance of an elegant young beau, in full evening dress. His face was white, with black hair parted in the middle; and whiskers, fiercely curled up at the end, gave him a martial look. Every one admired him, and a vainer puss never caught a mouse. If he saw us looking at him, he instantly took an attitude; gazed pensively at the fire, as if unconscious of our praises; crouched like a tiger about to spring, and glared, and beat the floor with his tail; or lay luxuriously outstretched, rolling up his yellow eyes with a sentimental expression that was very funny. We named him the Czar, and no tyrannical emperor of Russia ever carried greater desolation and terror to the souls of his serfs, than this royal cat did to the hearts and homes of the rats and mice over whom he ruled. The dear little mice who used to come out to play so confidingly in my room, live in my best bonnet-box, and bring up their interesting young families in the storeroom, now fell an easy prey to the Czar, who made nothing of catching half a dozen a day. Brazen-faced old rats, gray in sin, who used to walk boldly in and out of the front door, ravage our closets, and racket about the walls by night, now paused in their revels, and felt that their day was over. Czar did not know what fear was, and flew at the biggest, fiercest rat that dared to show his long tail on the premises. He fought many a gallant fight, and slew his thousands, always bringing his dead foe to display him to us, and receive our thanks. It was sometimes rather startling to find a large rat reposing in the middle of your parlor; not always agreeable to have an excited cat bounce into your lap, lugging a half-dead rat in his mouth; or to have visitors received by the Czar, tossing a mouse on the door-steps, like a playful child with its cup and ball.
