Fortunately, just in time to prevent a general squabble, the Eteraedarium, who had not been one of the number to patronize the roundabout, returned with the information that there were some swings a little way off. Despite their unfortunate experience on the roundabout, there was a general rush on the part of the creatures for this new attraction, and the Dodo and the Eteraedarium had hard work to secure a swing for themselves. "Shall I give you a push?" asked the Doctor, kindly, though with a curious gleam in his eye. "Yes, please," said the Dodo, gratefully. "All right," said the Doctor. "Hold tight!" And he gave a mighty shove, sending the swing high above all the others. "It's very--very nice," gasped the Dodo, "but don't push any higher, please." "Hold tight," said the Doctor, relentlessly, giving another shove, harder than before. "Oh! please--please d--don't, or we shall be upset," implored the Dodo, nervously, as the swing shot up into the air. "I'll teach you to twizzle me on the roundabout," cried the Doctor, vindictively. "Will you ever do it again?" [Illustration: "Fidge was delighted."] "Oh! no, n--no, never!" promised the Dodo. "Well, one good one for the last, then," cried the Doctor, giving a final push, and then leaving the poor Dodo to his fate. I don't think that it could have been a very dreadful one, however, for a few minutes later he had joined the three children and the Palaeotherium in a journey on the switchback. Fidge, who had never been on one before, was delighted with the experience, and shouted, "Hooray! This is jolly!" as the car dashed down the steep incline. The poor Palaeotherium, however, his nerves evidently greatly unstrung by his unfortunate experience on the roundabout, was dreadfully upset, and alarmed, and, hiding his eyes, he crouched at the bottom of the car till it reached the other end, when he at once got out, and no amount of persuasion would induce him to undertake the return journey. He had scarcely got out into the grounds again, when he met the Archaeopteryx, who was carrying a strange-looking object, which he held up for the Palaeotherium's inspection. "Your tail, I believe," he said. The Palaeotherium gave a hasty glance at his back, and then said, in rather a shamefaced way-- [Illustration: "Does this belong to you?"] "Thank you! Yes, it is. You see, I have been obliged to wear a false one for some time; I had no idea, however, that it had become detached." And he carefully adjusted it again, tying it on with a couple of tapes, and artfully concealing the ends. "Our family," he whispered, "have no tails to speak of, and, as we look rather remarkable without them, most of us wear artificial ones; but please don't tell the others, they are sure to make fun of me, if you do." "All right," promised the Archaeopteryx, kindly; "I won't, if you don't wish me to; but I----"
