But something must have been wrong with the Wizard's magic, or the creatures had magic of their own, for no sooner were the words spoken than the bushes began to move. At first they only waved their branches at the girl and little man, but pretty soon they began to slide over the ground, their roots dragging through the earth, and one pushed itself against the Wizard and pricked him so sharply with its thorns that he cried out: "Ouch!" and started to run away. [Illustration] Ozma followed, for the other bushes were trying to stick their thorns into her legs and one actually got so near her that it tore a great rent in her beautiful dress. The girl Princess could run, however, and she followed the fleeing Wizard until he tumbled head first over a log and rolled upon the ground. Then she sprang behind a tree and shouted: "Quick! Transform them into something else." The Wizard heard, but he was much confused by his fall. Grabbing from his bag the first magical tool he could find he transformed the bushes into three white pigs. That astonished the Imps. In the shape of pigs--fat, roly-poly and cute--they scampered off a little distance and sat down to think about their new condition. Ozma drew a long breath and coming from behind the tree she said: "That is much better, Wiz, for such pigs as these must be quite harmless. No one need now fear the mischievous Imps." "I intended to transform them into mice," replied the Wizard, "but in my excitement I worked the wrong magic. However, unless the horrid creatures behave themselves hereafter, they are liable to be killed and eaten. They would make good chops, sausages or roasts." [Illustration] [Illustration] But the Imps were now angry and had no intention of behaving. As Ozma and the little Wizard turned to resume their journey, the three pigs rushed forward, dashed between their legs, and tripped them up, so that both lost their balance and toppled over, clinging to one another. As the Wizard tried to get up he was tripped again and fell across the back of the third pig, which carried him on a run far down the valley until it dumped the little man in the river. Ozma had been sprawled upon the ground but found she was not hurt, so she picked herself up and ran to the assistance of the Wizard, reaching him just as he was crawling out of the river, gasping for breath and dripping with water. The girl could not help laughing at his woeful appearance. But he had no sooner wiped the wet from his eyes than one of the impish pigs tripped him again and sent him into the river for a second bath. The pigs tried to trip Ozma, too, but she ran around a stump and so managed to keep out of their way. So the Wizard scrambled out of the water again and picked up a sharp stick to defend himself. Then he mumbled a magic mutter which instantly dried his clothes, after which he hurried to assist Ozma. The pigs were afraid of the sharp stick and kept away from it.
