NICK RIBSAM was partly right in his supposition about his missing friend, Herbert Watrous.

That young gentleman rode along the lower trail, as confident as anyone could be that he was right and Nick was wrong. He did not press Jill, for the pony had done considerable hard riding during the day, but he arrived at the end of his brief journey a little in advance of the other.

“I knew it,” he said at the moment of catching sight of the pool of clear water, which, like the spring, was slightly to the right of the path; “there aren’t many brighter boys than Nick, but he makes his mistake once in a while, like other folks.”

And then, as his pony walked forward to drink, his rider gave out the signal intended to summon Nick to the spot.

“He will feel cheap when he finds he is wrong, but he is manly enough to own up to it, and admit that some folks know——”

Sitting astride of his animal while he was helping himself to a drink, Herbert made good use of his eyes. Just then he observed that, though the pool resembled a natural spring, it was not. It was fed by a stream pouring into the upper portion, as large as that which formed the outlet, while there was no bubbling from the bottom.

“Whew!” whistled the astonished youth; “it begins to look as if it wasn’t Nick that had made a slip—hello!”

At that moment the call came ringing down from the upper trail. The matter was settled. Nick had struck the right spot, and all Herbert could do was to ride back along the path to the fork and join him.

He was on the point of starting back, when it occurred to him that it might be possible to shorten the distance by cutting across the neck of land, as talked about before they parted. The promise of being able to do so looked more encouraging from below than above.

Slipping down from the saddle, Herbert began picking his way through the rough portion, and advanced several rods before reaching a section where a horse would find the travelling difficult.

“He could make his way this far easily enough,” he said, halting and looking back, “but it doesn’t seem so easy further on.”

He advanced more carefully, for he was beginning to doubt the feasibility of the plan. It will be readily seen that while he was so uncertain as to the best course, he was consuming more time than he suspected. Night was rapidly closing in, and he was still debating what was best to do, when he noticed the increasing cold.

“It’s the norther, sure enough!” he exclaimed, starting back to mount his horse; “a little late, but it’s getting there all the same.”

In fact it “got there” with such emphasis that, before Herbert could force his way to the pool of water, lie thought he would freeze to death. There was no need of answering the signal of Nick, and, catching sight of the outlines[135] of what seemed a mass of rocks in the darkness, he made for them, intent only on securing shelter for the moment, or until the cutting wind abated enough to allow him to venture out to recover his horse.

Meanwhile, the latter, who had had more than one previous experience with northers, was trying to help himself somewhat after the same fashion as his master. Since the arctic breath from the distant Rocky Mountains came from the north, Jill began edging away from it by taking the back trail, just as cattle drift before a long continued and violent storm of sleet and snow.

It must not be supposed that the pony held any purpose of deserting his master. He had never tried to do anything of the kind, and it would be injustice to accuse him in the present instance; but the instinct of self-preservation was as strong in him as in any other animal, and he saw no other way of lessening his sufferings than by edging along the back trail.

When he reached the fork where the two paths separated, he may have recalled his situation and he may not. Be that as it may,[136] it was too much to expect him to face about and advance in the teeth of the norther, before which he had retreated so far, unless he was compelled to do so. No one was there to urge him with spur, and instead, therefore, of turning his course, he kept on.

He had moved so reluctantly to this point that he did not reach it until Nick Ribsam knelt down a short distance off and put his e............
