"Oh, I shouldn't have started back, I should have waited," in Kit's voice was a sob.
Heavy clouds had shut out all the blue of the sky. Never before had the girls seen such black and menacing clouds. They rolled and seethed like foaming billows. It looked as if the demons of some underworld were engaged in a tremendous battle. Black, castle-like shapes piled up, to be tumbled into the abyss, the next second. It was an inferno through which a flash of lightning darted from time to time, followed by thunderclaps.
The girls were terrified.
Joy was sobbing outright and at every blast of thunder a high-pitched, uncontrollable shriek broke from her lips. The horses stood still, trembling with fright.
"We're in terrible danger here. We must get out!" cried Kit, frantically. "Come on back. Let your horse take you wherever he wants to, and hold on for dear life."
Kit wheeled her horse back the way they had come and the girls followed. And just at that moment the downpour came and looking back toward the pass, the girls saw a strange sight. A body of water came roaring through the narrow opening as if a gigantic fire-hydrant had burst. A cloudburst in the mountain beyond had sent the water roaring and tumbling down the bed of the stream.
Just what happened the girls could hardly tell afterwards. They held on as Kit had directed and the horses raced madly away from the oncoming torrent.
Bet's heart almost stopped beating as her pony took the trail up the wall of the canyon, so steep that she would not have dared to attempt it on foot. Half way up the wall, the horse stopped.
"I've never seen anything braver than that! This is thrilling!" breathed Bet as she held on to the horn of the saddle with a grip that strained her hands. Although she was as frightened as any of the girls, she still had an eye to the adventure.
The stream bed was a river now, swirling, foaming and roaring. It made one dizzy to look down into it.
