What power must have been required to shatter and to sweep away the missing parts of this pyramid; for we do not see it surrounded by heaps of fragments: one only sees other peaks—themselves rooted to the ground—whose sides, equally rent, indicate an immense mass of débris, of which we do not see any trace in the neighborhood. Doubtless this is that débris which, in the form of pebbles, boulders and sand, fills our valleys and our plains,—de Saussure. Two summits amongst those in the Alps which yet remained virgin had excited my admiration. One of these had been attacked numberless times by the best mountaineers without success: the ether, surrounded by traditional inaccessibility, was almost untouched. These mountains were the Weisshorn and the Matterhorn. After visiting the great tunnel of the Alps in 1861, I wandered for ten days in the neighboring valleys, intending presently to attempt the ascent of these two peaks. Rumors were floating about that the former had been conquered, and that the latter was shortly to be attacked, and they were confirmed on my arrival at Chatillon, at the entrance of the Val Tournanche. My interest in the Weisshorn abated, but it was raised to the highest pitch on hearing that Professor Tyndall was at Breuil, and intending to try to crown his first victory by another and a still greater one. Up to this time my experience with guides had not been fortunate, and I was inclined, improperly, to rate them at a low value. They represented to me pointers-out of paths and great consumers of meat and drink, but little more; and, with the recollection of Mont Pelvoux, I should have greatly preferred the company of a couple of my countrymen to any number of guides. In answer to inquiries at Chatillon, a series of men came forward whose faces expressed malice, pride, envy, hatred and roguery of every description, but who seemed to be destitute of all good qualities. The arrival of two gentlemen with a guide, who they represented was the embodiment of every virtue and exactly the man for the Matterhorn, rendered it unnecessary to engage any of the others. My new guide in _physique_ was a combination of Chang and Anak; and although in acquiring him I did not obtain exactly what was wanted, his late employers did exactly what _they_ wanted, for I obtained the responsibility, without knowledge, of paying his back fare, which must have been a relief at once to their minds and to their purses.
