Partly because Jumbo was so old, and partly because he was also very bad tempered, he lived by himself in a comfortable, roomy hutch, with a soft bed of hay at one end and a great wide space at the other, in which he took his meals and looked out of the door at the other rabbits.  Helen, who did not care very much for Jumbo, declared that he did that on purpose to aggravate them, for they all finished their food long before he was half-way through his, and then they had nothing else to do but to sit and watch him.  And that made them feel hungry again. He was sitting before his door now munching bran and oats, and at the mention of his name he pricked up his long ears and sleepily blinked his eyes.  "H'm," said Helen, looking at him rather distrustfully; "Jumbo too can be dreadfully naughty when he likes, and he rather looks as if he meant it to-day."
