Still, during all those interminable hours, Helen watched where she was traveling, and if she ever returned over that trail she would recognize it. The afternoon appeared far advanced when Dale and Roy led down into an immense basin where a reedy lake spread over the flats. They rode along its margin, splashing up to the knees of the horses. Cranes and herons flew on with lumbering motion; flocks of ducks winged swift flight from one side to the other. Beyond this depression the land sloped rather abruptly; outcroppings of rock circled along the edge of the highest ground, and again a dark fringe of trees appeared.
How many miles! wondered Helen. They seemed as many and as long as the hours. But at last, just as another hard rain came, the pines were reached. They proved to be widely scattered and afforded little protection from the storm.
Helen sat her saddle, a dead weight. Whenever Ranger quickened his gait or crossed a ditch she held on to the pommel to keep from falling off. Her mind harbored only sensations of misery, and a persistent thought--why did she ever leave home for the West? Her solicitude for Bo had been forgotten. Nevertheless, any marked change in the topography of the country was registered, perhaps photographed on her memory by the torturing vividness of her experience.
The forest grew more level and denser. Shadows of twilight or gloom lay under the trees. Presently Dale and Roy, disappeared, going downhill, and likewise Bo. Then Helen's ears suddenly filled with a roar of rapid water. Ranger trotted faster. Soon Helen came to the edge of a great valley, black and gray, so full of obscurity that she could not see across or down into it. But she knew there was a rushing river at the bottom. The sound was deep, continuous, a heavy, murmuring roar, singularly musical. The trail was steep. Helen had not lost all feeling, as she had believed and hoped. Her poor, mistreated body still responded excruciatingly to concussions, jars, wrenches, and all the other horrible movements making up a horse-trot.
For long Helen did not look up. When she did so there lay a green, willow-bordered, treeless space at the bottom of the valley, through which a brown-white stream rushed with steady, ear-filling roar.
Dale and Roy drove the pack-animals across the stream, and followed, going deep to the flanks of their horses. Bo rode into the foaming water as if she had been used to it all her days. A slip, a fall, would have meant that Bo must drown in that mountain torrent.
Ranger trotted straight to the edge, and there, obedient to Helen's clutch on the bridle, he halted. The stream was fifty feet wide, shallow on the near side, deep on the opposite, with fast current and big waves. Helen was simply too frightened to follow.
