It was rather a slippery bridge, and Rosy was rather scared at this big, strange boat; but she got safely over, and held on fast; then, with a roll and a plunge, off went the whale, spouting two fountains, while his tail steered him like the rudder of a ship. Rosy liked it, and looked down into the deep sea, where all sorts of queer and lovely things were to be seen. Great fishes came and looked at her; dolphins played near to amuse her; the pretty nautilus sailed by in its transparent boat; and porpoises made her laugh with their rough play. Mermaids brought her pearls and red coral to wear, sea-apples to eat, and at night sung her to sleep with their sweet lullabies. So she had a very pleasant voyage, and ran on shore with many thanks to the good whale, who gave a splendid spout, and swam away. Then Rosy travelled along till she came to a desert. Hundreds of miles of hot sand, with no trees or brooks or houses. "I never can go that way," she said; "I should starve, and soon be worn out walking in that hot sand. What _shall_ I do?" "Quee, quee! Wait and see: You were good to me; So here I come, From my little home, To help you willingly," said a friendly voice; and there was the mouse, looking at her with its bright eyes full of gratitude. "Why, you dear little thing, I'm very glad to see you; but I'm sure you can't help me across this desert," said Rosy, stroking its soft back. "That's easy enough," answered the mouse, rubbing its paws briskly. "I'll just call my friend the lion; he lives here, and he'll take you across with pleasure." "Oh, I'm afraid he'd rather eat me. How dare you call that fierce beast?" cried Rosy, much surprised. "I gnawed him out of a net once, and he promised to help me. He is a noble animal, and he will keep his word." Then the mouse sang, in its shrill little voice,-- "O lion, grand, Come over the sand, And help me now, I pray! Here's a little lass, Who wants to pass; Please carry her on her way." In a moment a loud roar was heard, and a splendid yellow lion, with fiery eyes and a long mane, came bounding over the sand to meet them. "What can I do for you, tiny friend?" he said, looking at the mouse, who was not a bit frightened, though Rosy hid behind a rock, expecting every moment to be eaten. Mousie told him, and the good lion said pleasantly,-- "I'll take the child along. Come on, my dear; sit on my back and hold fast to my mane, for I'm a swift horse, and you might fall off."
