To Vosper and Lounsbury the two little sentences were just the assurances of a hired employee, half-felt and forgotten soon. But Virginia heard more clearly. She had a vague feeling that she was a witness to a vow. It seemed to her that there was the fire of a zealot in his dark eyes, and by token of some mystery she did not understand, this strong man had seen fit to give her his oath. She only knew that he spoke true, that by a secret law that only strong men know he would be as faithful to this promise as if he had given bond.

It was one of the decrees of the forest gods that no human being shall ride for five miles through the spruce forests of the Selkirks and fail to glean at least some slight degree of wilderness knowledge. Both Virginia and Lounsbury had been on horseback before. Virginia had ridden in the parks of her native city: long ago and far away a barefoot, ragged boy—much to be preferred to the smug and petulant man who now tried to hard to forget those humble days—had bestrode an old plow horse nightly on the way to a watering trough. But this riding had qualities all its own. There was no open road winding before them. Nor was there any trail,—in general or particular.

It was true that the moose had passed that way, leaving their great footprints in the dying grass. They had chosen the easiest pathway over the hills, and Bill was enough of a woodsman to follow where they led. Traversing the Clearwater was simply a matter of knowing the country and going in a general direction. Almost at once the evergreen thickets closed around them.

Virginia found that safety depended upon constant watchfulness. The evergreen branches struck cruel blows at her face, the spruce needles cut like knives. Sometimes the horse in front would bend down a young tree, permitting it to whip back with a deadly blow; she had to watch her knees in the narrow passages between the trunks; and the vines reached and caught at her. Sometimes the long-hanging limbs of the young trees made an impassable barrier, and more than once she was nearly dragged from the saddle. Shortly they came to the first fallen log.

Mulvaney, Bill's horse, took it lightly; and the man turned to watch the girl. Her horse stepped gingerly, making it without trouble. Then the guide saw fit to give her a little good advice.

"Kick Buster in the ribs just before you come to a log," he said. "He'll jump 'em then. It's a whole lot safer—if he tries to step over 'em he's apt to get his foot caught and give you a bad fall."

Virginia looked up coldly. She wasn't accustomed to being spoken to in quite this tone of voice, particularly by an employee. But she saw his sober eyes and immediately forgot her resentment. And she found an actual delight in bounding over the next obstruction.

"And there's one more thing," the guide went on. "I've ridden plenty of horses, and I've found there's only one way to handle 'em. I'm going to try a new way to-day, because there's a lady in the party. But if I'm tried too heavy——"
