Although the traveller, when he reaches Montauvert, can look directly down upon the glacier, he cannot descend to it there; for, opposite to the inn, the valley of ice is bordered by cliffs and precipices a thousand feet high. It is necessary to follow along the bank two or three miles among stupendous rocks and under towering precipices, until at length a place is reached where, by dint of much scrambling and a great deal of help from the guide, it is possible to descend. [Illustration: THE NARROW PATH.] Rollo was several times quite afraid in making this perilous excursion. In some places there seemed to be no path at all; and it was necessary for him to make his way by clinging to the roughnesses of the rocks on the steep, sloping side of the mountain, with an immense abyss yawning below. There was one such place where it would have been impossible for any one not accustomed to mountain climbing to have got along without the assistance of guides. When they reached this place, one guide went over first, and then reached out his hand to assist Rollo. The other scrambled down upon the rocks below, and planted his pike staff in a crevice of the rock in order to make a support for a foot. By this means, first Mr. George, and then Rollo, succeeded in getting safely over. Both the travellers felt greatly relieved when they found themselves on the other side of this dangerous pass. In coming back, however, Rollo had the misfortune to lose his pike staff here. The staff slipped out of his hand as he was clinging to the rocks; and, after sliding down five or six hundred feet to the brink of the precipice, it shot over and fell a thousand feet to the glacier below, where it entered some awful chasm, or abyss, and disappeared forever. Mr. George and Rollo had a pretty hard time in scrambling over the moraine when they came to the place where they were to get upon the glacier. When they were fairly upon the glacier, however, they could walk along without any difficulty. It was like walking on wet snow in a warm day in spring. Little brooks were running in every direction, the bright waters sparkling in the sun. The crevasses attracted the attention of the travellers very strongly. They were immense fissures four or five feet wide, and extending downward perpendicularly to an unfathomable depth. Rollo and Mr. George amused themselves with throwing stones down. There were plenty of stones to be found on the glacier. In fact, rocks and stones of all sizes were scattered about very profusely, so much so as quite to excite Mr. George's astonishment. "I supposed," said he, "that the top of the glacier would be smooth and beautiful ice." "I did not think any thing about it," said Rollo. "I imagined it to be smooth, and glassy, and pure," said Mr. George; "and, instead of that, it looks like a field of old snow covered with scattered rocks and stones."
