"What will become of Mrs. Shirley's party here, I wonder," said Roly, after a hard day's work.

"If they are wise," replied Uncle Will, "they'll stop at Pleasant Camp. The two young men can make a dash in for claims when the lame one has recovered, but those ladies can never stand this kind of work."

David declared that never before had he appreciated the picture in his room at home, of Napoleon's soldiers dragging cannon over the Alps. He was quite sure he would groan with genuine sympathy when he saw it again. In the mean time, in spite of all discomforts, he was daily securing beautiful and interesting views of mountains and valleys, of camps and the sledding, and of all the unique phases of his outdoor life.

At one point, he photographed a curious phenomenon beside the trail. The stump of a tree bore upon its top a great skull-shaped mass of snow, while underneath on every side the flakes had been packed against the bark by the wind, the whole forming a colossal figure of a human head and neck, which appeared as if carved in purest marble.

Now and then they observed traces of the company ahead. Sometimes it was a broken gee-pole, again a deserted camping-ground or fireplace, and frequently bits of rope, empty cracker boxes and tins, or a freshly "blazed" or notched tree to indicate the trail. But the Thirty-six themselves were as elusive as if they all wore seven-league boots, and the Bradfords never caught sight of them during these days, no matter how hard they worked.

In the forest through which they were travelling, spruce gum of fine quality could be picked from many of the trees, and the boys found it useful as a preventive of thirst in a country where open springs were far between. Often, too, they carried beef tablets in their pockets, and these served to alleviate hunger as well as thirst,—for so severe was the work, and so stimulating to the appetite the mountain air, that they were fairly faint between meals.

Once, while on the march, they were startled by a deep rumbling, which seemed to come from the bowels of the earth. Uncle Will said that this was the sound of an avalanche on the high mountains across the Klaheena valley.

Porcupines were so numerous as to be obtainable as often as needed, but Roly one day discovered a new kind of game. He espied a large dark bird sitting on a low branch of a spruce near the trail, and called Uncle Will's attention to it.

"Ah!" exclaimed the latter, "that's a spruce partridge, and very good eating. Is your revolver loaded, Charles?"
