From an arched ice cavern at its base poured the milk-white river, with a hollow roaring, and such force that fair-sized bowlders were swept down its channel as though they were so many sticks of wood. The whole scene was of such fascinating interest that it very nearly brought poor Bonny to grief.

BONNY WAS JERKED VIOLENTLY BACKWARD.

He had dismounted, and was preparing to follow M. Filbert and Alaric, who had already led their ponies in safety across the narrow bridge. These animals had crossed so readily that he supposed his would do the same, and, as he stepped out on the great log, was paying far more attention to the glacier than to it. Suddenly he was jerked violently backward, pitched headlong down the bank, and barely saved himself from the icy torrent by clutching at a friendly bush. At the same moment his pony, who had no confidence in mountain bridges, dashed into the roaring stream, was instantly swept from his footing, rolled over and over, and borne struggling away toward what seemed certain destruction. By the good fortune that attends all fools, animals as well as human, he managed to escape both drowning and broken bones, and finally regained his feet on a friendly reef that projected into the river a quarter of a mile below the bridge. There he stood trembling, bruised, and dripping when Bonny and one of the Indians, who had hastened down the bank to discover his fate, found him a few minutes later. From that time forth he was the meekest and most docile pony imaginable, suffering himself not only to be led over the log bridge without remonstrance, but wherever else his young master desired.

High above this lovely valley, and close to the line where snow and timber met, M. Filbert called a halt, and ordered the permanent camp to be pitched. Although this point was less than half-way to the top of the mountain, or only 6500 feet above sea-level, the ponies could climb no higher, and, after being unladen, were sent back in charge of the packers into Paradise Valley, where they might fatten on its juicy grasses until needed for the return trip.

From here, then, the ragged slope of ice, snow, and rock that stretched indefinitely upward toward the far-away shining summit must be traversed on foot or not at all. But this was not to be done now nor for days to come, during which the camp just pitched was to be the base of a widespread series of explorations. A few straggling hemlocks, so bent by the ice-laden winds that swept down the mountain-side in winter that they looked like decrepit old men, furnished shelter, fuel, and bedding.

"It beats the sloop away out of sight," remarked Bonny.

"Or Skookum John's," said Alaric.

"Yes, or being chased and starved."

"The best of it all is that up here I seem to amount to something," added Alaric.
