"Now don't tell me this is real," grunted the dummy, sitting down with a thud. "I wouldn't believe them, even in a picture." "But they're not in a picture," wailed Dorothy. "They're here, whether you believe them or not. Why they have sails! Oh Humpy, get up quick. Aren't you going to help me?" With a mighty effort Humpy pulled himself together and arose. "Teg tuo! Teg tuo!" shrilled the dummy, lapsing in his fright and excitement into the terrible language of Back. "Og yawa! Og yawa! Kcab Sdoow!" And snatching off his crown, he hurled it violently at the heads of the approaching rivermen. CHAPTER 12 The Playful Scooters The first of the rivermen caught the dummy's crown neatly and tossed it back. "Is it a game?" he called hoarsely. Dorothy had no time to dodge, so she quickly caught the crown, which came with such force that she sat down with a jolt. The dummy danced up and down and waved his arms threateningly. "Come on, Flub Blub. It's a game," called the first riverman to the man just behind him. "Two Scoots playing a game! Here," he croaked in his deep, frog-like voice, "throw it to me!" He raised his sails coaxingly at Dorothy and, partly because she was afraid to have him come nearer and partly because she didn't know what else to do, the little girl pitched back the crown with all her might. The one called Flub Blub caught it immediately. The next throw was to Humpy and backward and forward between the puzzled travellers on the bank and curious creatures on the water flew the dummy's crown, and breathlessly between catches Dorothy examined these strange playfellows. They were tall and angular and so sunburned that they almost appeared to be Indians. They were clad in shiny water proof hats and slickers. On their long, thin feet, shaped somewhat like skis and somewhat like narrow boats, they slid over the water as surely and carelessly as we skate about on ice. Extending from the ankle to the finger tips, and as much a part of the wearer as wings are part of a bird, were bright yellow sails. When their arms were down at their sides, the sails were folded in and almost unnoticeable, but with arms outstretched the rivermen had two wide-spread sails to help them scoot over the water. By lowering the right arm or the left, they could turn, tack and get about faster than any sailing boat you have ever seen. Their faces, under the broad sou-westers, were child-like and pleasant and, finding them more interesting than dangerous, Dorothy motioned for Humpy to hold the crown, which had landed for about the tenth time with a resounding thwack against his chest. "But I was just getting good," objected the dummy, placing the crown regretfully on his head. "What now?" Humpy had become so engrossed in catching the crown that he had quite forgotten his fright and, as the leader came in close to the shore, he looked at him with frank curiosity.
