And thus each of the creatures took up their respective positions, and the children thought it best to follow their example. Dick and Fidge climbed up to one of the upper berths, and Marjorie made herself comfortable in the one below them. "It's much better than being in those horrid little tents on the draughty station," she called out; "and we are sure to get to _somewhere_ in this train, aren't we, Dick?" "Yes, rather," was her elder brother's reply. "I say, Sis, what are we going to do when they ask us for our tickets at the Crystal Palace? I haven't got any money except this two shillings, have you?" "Not a penny," admitted Marjorie. "However," she added, yawning sleepily, "I suppose it will all come right; none of the other creatures took tickets, you know. The great thing is to get back to England." "There's a window up here, and I have just looked out," said Dick, "it's all pitch dark." "Yes," murmured Marjorie; "Underground Railway to Crystal Palace; that's how we went last time, you know--part of the way, at any rate--let's go to sleep now. Good-night, Dick." "Good-night." "Nighty, nighty!" shouted Fidge. "Good-night, Fidge, dear," was his sister's reply, in a very tired voice. A moment afterwards the train gave a lurch, and there was a crash and a loud cry from one of the lower berths. Dick hastily scrambled down to ascertain what was the matter, and found that the Dodo had tumbled out of bed. "Bless my gloves and beak!" ejaculated the bird, as he picked himself up; "it's enough to frighten one out of their lives, isn't it?" "Have you hurt yourself much?" inquired Dick, kindly. "No; I don't think so," said the Dodo, carefully feeling himself all over to see if any bones were broken. "How do you like my nightcap?" he inquired, suddenly and inconsequently. "Does it suit me?" "Oh, it's all right, I suppose," said Dick, laughing in spite of himself at the bird's vanity. "Where did you get it?" "Found it under my pillow," announced the bird, triumphantly. "That's why I tumbled out of bed, so that some one at any rate, should come and see me in it. Nobody else seems to be coming, though," he added, looking anxiously up and down, "so I shall go to bed again; but I shall leave my curtains wide open, so that if anybody passes by during the night, or in the morning, they will see how beautiful I am when I am asleep." At that moment there was an awful noise like a deep groan, which grew and grew in volume till it sounded like distant thunder, and then faded away and ended up with a comical little whistle. Again and again it was repeated. "Oh, Dick! what is it?" called Marjorie, putting her head outside the curtains. "I can't think," said Dick, in a puzzled voice. "Where have I heard that sound before?" exclaimed the Dodo, putting one finger of the glove to his forehead, and striking a thoughtful attitude. "Ah! I have it," he cried. "Of course, it's a prehistoric snore--the Doctor is asleep."
