She waved her silver wand over the pool and the crab instantly became snow-white--all except his eyes, which remained black. The creature saw his reflection in the water and was so delighted that he at once climbed out of the pool and began moving slowly toward the web, by backing away from the pool. He moved so very slowly that Dorothy cried out impatiently: "Dear me, this will never do!" Catching the crab in her hands she ran with him to the web. She had to hold him up even then, so he could reach with his claws strand after strand of the filmy purple web, which he was able to sever with one nip. When enough of the web had been cut to allow them to pass, Dorothy ran back to the pool and placed the white crab in the water, after which she rejoined Ozma. They were just in time to escape through the web, for several of the purple spiders now appeared, having discovered that their web had been cut, and had the girls not rushed through the opening the spiders would have quickly repaired the cuts and again imprisoned them. Ozma and Dorothy ran as fast as they could and although the angry spiders threw a number of strands of web after them, hoping to lasso them or entangle them in the coils, they managed to escape and clamber to the top of the hill. CHAPTER 3 The Mist Maidens From the top of the hill Ozma and Dorothy looked down into the valley beyond and were surprised to find it filled with a floating mist that was as dense as smoke. Nothing in the valley was visible except these rolling waves of mist, but beyond, on the other side, rose a grassy hill that appeared quite beautiful. "Well," said Dorothy, "what are we to do, Ozma? Walk down into that thick fog, an' prob'bly get lost in it, or wait till it clears away?" "I'm not sure it will clear away, however long we wait," replied Ozma, doubtfully. "If we wish to get on, I think we must venture into the mist." "But we can't see where we're going, or what we're stepping on," protested Dorothy. "There may be dreadful things mixed up in that fog, an' I'm scared just to think of wading into it." Even Ozma seemed to hesitate. She was silent and thoughtful for a little while, looking at the rolling drifts that were so gray and forbidding. Finally she said: "I believe this is a Mist Valley, where these moist clouds always remain, for even the sunshine above does not drive them away. Therefore the Mist Maids must live here, and they are fairies and should answer my call." She placed her two hands before her mouth, forming a hollow with them, and uttered a clear, thrilling, bird-like cry. It floated far out over the mist waves and presently was answered by a similar sound, as of a far-off echo.
