This was, after all, the true secret of our lads' content; for, in spite of its novelty, the present situation would quickly have grown wearisome had they not been constantly and happily occupied. Every day that the weather would permit they tramped from early morning until dark over snow-fields and glaciers, sealed cliffs, scrambled down into valleylike meadows set like green jewels in the grim mountain-side, threaded their way amid the fantastic forms of stunted forests, toiled slowly up lofty heights, or slid with the speed of toboggans down gleaming slopes. Each day they gained in agility and daring, and each night they returned to that cheery camp with its light, warmth, and abounding comforts, so healthfully tired and so ravenously hungry that it is no wonder they grew to look upon it as a home and a very pleasant one.

Both lads developed specialties in which they became expert. Alaric's was photography, an art that he had acquired in France, and had practised at intervals for more than a year. As soon as M. Filbert discovered this knowledge on the part of his young interpreter, he entrusted him with the camera, and never had the lad devoted himself to anything with such enthusiasm, as he now did to the capturing of views. His greatest triumph came through hours of tedious and noiseless creeping over a rough icefield that finally placed him within twenty yards of a couple of mountain-goats.

Although the wind was blowing strongly from them to him, the timid creatures were already alarmed, and were sniffing the air suspiciously, when a click of the camera's shutter sent them off like a flash. But the shot had been successful, as was shown by the development of a perfect plate that evening. M. Filbert was jubilant over this feat, which he said had never before been accomplished, and complimented the lad in flattering terms upon the skilful patience that had led to it.

Bonny's specialty lay in the collecting of flowers, to which he had devoted himself assiduously ever since learning that they were what the little Frenchman most desired. Keen-eyed, nimble-footed, and tireless, he discovered and secured many a rare specimen that but for him would have been passed unnoticed.

Thus the leader of the expedition found reason to value the good qualities of his young assistants more highly with each day, and was already planning to have them accompany him on his entire American tour, during which he proposed to ascend at least a dozen more mountains. Bonny was jubilant over the prospect of such a trip, and was now as eager to learn French, in order to qualify himself for it, as he had formerly been scornful of the language.

With all this open-air life and splendid physical exercise the one-time pale-faced and slender Alaric was broadening and developing beyond belief. His cheeks were now a ruddy brown, his eyes were clear, his muscles hard, and his step as springy as that of a mountain-goat. Above everything else in his own estimation he was learning to swing an axe with precision, and could now chop a log in two almost as neatly as Bonny himself.

For all that they were so constantly and agreeably occupied, the boys were possessed of a great and ever-increasing longing to stand on the lofty but still distant summit, with the general aspect of which they had become so familiar during their stay in the timber-line camp. Thus, when one evening M. Filbert decided to make a start toward it on the morrow, they hailed the announcement with joy. One of the Indians was to accompany them as guide, while his fellow was to be left with François to keep camp.

The greater part of the following morning was devoted to making preparations for the climb and what was thought might prove a three days' absence from camp. The hobnails of their walking-boots, worn smooth by friction, were replaced by a fresh set. Alpenstocks were tested until it was certain that each of those to be taken would bear the weight of the heaviest of the party. Provisions were cooked and packs laid out. Each was to carry a canvas-covered blanket sleeping-bag, inside of which would be rolled provisions for three days, a tin plate, and a cup. Each was also provided with a sheath-knife and a supply of matches. Besides these things M. Filbert was to carry a barometer, a thermometer, a compass, and a collecting-case. Alaric was entrusted with the camera and two dozen plates. Bonny's extras were a hatchet and a fifty-foot coil of stout rope; while the Indian was to carry an ice-axe, and pack a burden of fire-wood.

It was nearly noon when, fortified by a hearty lunch, they left their homelike camp, and facing resolutely upward, began a tedious climb over the limitless expanse of snow that they struck within the first hundred yards. The climb of that afternoon was hot, in spite of the snow that crunched beneath their feet, tedious, and only mildly exciting, for all the perils of the ascent were to come on the morrow. Shortly before the sun sank into the sea of cloud that spread in fleecy undulations beneath them, they reached the base of the Cleaver, a gigantic ridge that seemed to bar their further progress. Here, on a small plat of nearly level ground from which they dug away the snow, they made a fire over which to boil water for a pot of tea, ate supper, and prepared to pass the night. They were four thousand feet above timber-line, and two miles higher than the waters of Puget Sound.

As soon as supper was over the entire party crawled into their sleeping-bags for protection against the bitter cold of the night, and for a while the two boys, nestling together, talked in low tones.
