She let the horse run, and when he had plunged to the foot of that slope of soft ground he broke out across the open bench at a pace that made the wind bite Helen's cheeks and roar in her ears. She lost sight of Dale. It gave her a strange, grim exultance. She bent her eager gaze to find the tracks of his horse, and she found them. Also she made out the tracks of Bo's mustang and the bear and the hound. Her horse, scenting game, perhaps, and afraid to be left alone, settled into a fleet and powerful stride, sailing over logs and brush. That open bench had looked short, but it was long, and Helen rode down the gradual descent at breakneck speed. She would not be left behind. She had awakened to a heedlessness of risk. Something burned steadily within her. A grim, hard anger of joy! When she saw, far down another open, gradual descent, that Dale had passed Bo and that Bo was riding the little mustang as never before, then Helen flamed with a madness to catch her, to beat her in that wonderful chase, to show her and Dale what there really was in the depths of Helen Rayner. Her ambition was to be short-lived, she divined from the lay of the land ahead, but the ride she lived then for a flying mile was something that would always blanch her cheeks and prick her skin in remembrance. The open ground was only too short. That thundering pace soon brought Helen's horse to the timber. Here it took all her strength to check his headlong flight over deadfalls and between small jack-pines. Helen lost sight of Bo, and she realized it would take all her wits to keep from getting lost. She had to follow the trail, and in some places it was hard to see from horseback. Besides, her horse was mettlesome, thoroughly aroused, and he wanted a free rein and his own way. Helen tried that, only to lose the trail and to get sundry knocks from trees and branches. She could not hear the hound, nor Dale. The pines were small, close together, and tough. They were hard to bend. Helen hurt her hands, scratched her face, barked her knees. The horse formed a habit suddenly of deciding to go the way he liked instead of the way Helen guided him, and when he plunged between saplings too close to permit easy passage it was exceedingly hard on her. That did not make any difference to Helen. Once worked into a frenzy, her blood stayed at high pressure. She did not argue with herself about a need of desperate hurry. Even a blow on the head that nearly blinded her did not in the least retard her. The horse could hardly be held, and not at all in the few open places. At last Helen reached another slope. Coming out upon canuon rim, she heard Dale's clear call, far down, and Bo's answering peal, high and piercing, with its note of exultant wildness. Helen also heard the bear and the hound fighting at the bottom of this canuon.
