Whiz! Buzz! Boom! With a whirl and dash the rushing head came tearing along, then--Zip! Spat! The bubble was splashing in a burst of water and light. The Comet Expressman looked back with an evil grin, and Bobbie went hurtling down--down--over and over--down--down. There below him was the big, deep sea. Down--down went Bobbie, and you may be sure he had no chance to think of any way to stop himself. Sometimes his head was where his heels ought to be, and sometimes he spun around like a top. And what was worse yet, once in a while, as he whirled about, he caught sight of the Comet Expressman, and that hideous head with the long sandy beard trailing out behind would wiggle its ears and grin. My! but Bobbie would have given anything to get hold of that long trailing sandy beard and give it a sharp tug or two. But just holding his breath gave Bobbie enough to do. Down--down--he fell--over and over--down and down. He caught one more sight of the wiggling ears when--Splash! But to his surprise Bobbie did n't stop. He kept on going down, down through the soft green water. Away, 'way down he went, to the bottom of the deep sea. “Well, anyway,” thought he, “I'm done with the Comet Expressman.” He could see nothing but water, and more water, and he certainly felt wet clear through. Then, having reached the bottom, Bobbie had another surprise. He began going up again as fast as he had gone down, and in a moment found himself on the surface, being carried swiftly along by a great foaming wave that was rushing toward the sandy shore, and-- Bump! There sat Bobbie in his garden at home! No wonder he was wet. The bubble bowl was upset and Fluff, the poodle, was just disappearing behind the lilac bush. The soapy water made a nice, cold, soaky puddle. A big, round, shining moon that made him think of the Comet Expressman seemed to be looking down and laughing at him. The garden was very quiet. Looking around, Bobbie spied a little white fuzzy head close beside him. “Fairy paint brush! Humph!” thought Bobbie, and he reached over to pluck a blade of grass. “Why, I declare,” he said, “the little new shoot just peeping out of the ground has almost no color at all. Think of all the grass that's been painted right in our own yard! Those Rainbow Fairies certainly have a good deal of work to do.” As Bobbie stood up, Fluff came bounding back. He leaped upon his little master as joyfully as though he had n't seen him for days and weeks. For a minute Bobbie felt that he really had been away on a long, long journey. Then he glanced down at the soapy little puddle behind him. “Fluff, sir,” he said with a frown, pretending to be very angry, “look at what you've done, and look at my clothes! But my whizaphats!” he added, seizing Fluff's paws. “If that dream had been true your ocean would have saved my life. If I'd landed on the _ground_ when the Comet Expressman hit me, no telling what _would_ have happened!”
