"Then what is the use of levelling?" asked Glen.

"Because these figures are only approximate, and cannot be relied upon for nice work. But where did you learn about such things, Grip?"

"At the Brimfield High School," answered Binney with some confusion; for he was not really so boastful of his scholarship as he had once been.

"Well, how would you like to join our climbing-party? I'm going to take Glen along for his muscle, and I'll take you for your brains if you want to go."

"I think I'd like to try it, though perhaps I won't be able to get to the very top," answered Binney.

The modesty that this boy had learned from his rough Plains experience would have surprised his Brimfield acquaintances could they have seen it.

"Very well, then, we will start at sunrise in the morning. We'll each carry a hatchet, a knife, matches in water-tight cases, and a good bit of lunch. I'll carry the barometer, Glen shall take charge of the thermometer, and 'Grip' shall bring along his brains. Now I'd advise you both to turn in, and lay up a supply of rest sufficient to carry you through a harder day's work than any we've done on this trip yet."

The sun was just lifting his red face above the distant rim of the Plains, and its scant beams were bathing the snow-capped peak in a wonderful rosy glow, as the three mountain climbers left camp the next morning. Each one bore the light weight allotted to him, and, in addition, Glen carried a raw-hide lariat hung over his shoulders.

Having noted the compass bearings of their general course, they plunged directly into the dense fir forest with which this flank of the mountain was covered to a height of a thousand feet or so above them. For several hours they struggled through it, sometimes clambering over long lanes of fallen trees, prostrated by fierce wind-storms, and piled in chaotic heaps so thickly that often, for half a mile at a time, their feet did not touch the ground. Then they came to a region of enormous granite blocks, ten to thirty feet high, over many of which they were obliged to make their way as best they could. Now they began to find patches of snow, and the timber only appeared in scattered clumps.

From here their course led up through an enormous gorge, or cleft, that grew narrower as they ascended, until it terminated in a long, steep slope of boulders and loose rocks. Here they encountered the first real danger of the ascent. Every now and then a boulder, that appeared firmly seated until burdened with the weight of one of them, would give way and go crashing and thundering down with great leaps behind them until lost in the forest below.
