“And how high!” I added. It was a discouraging sight. The famous wall of the ridge, so much feared, but which must be crossed, was before us, with its slope of fifty degrees. But after scaling the wall of the Corridor, it did not terrify us. We rested for half an hour and then continued our tramp; but we soon perceived that the atmospheric conditions were no longer the same. The sun shed his warm rays upon us; and their reflection on the snow added to our discomfort. The rarefaction of the air began to be severely felt. We advanced slowly, making frequent halts, and at last reached the plateau which overlooks the second escarpment of the Rouges rocks. We were at the foot of Mont Blanc. It rose, alone and majestic, at a height of six hundred feet above us. Monte Rosa itself had lowered its flag! Levesque and I were completely exhausted. As for M. N——, who had rejoined us at the summit of the Corridor, it might be said that he was insensible to the rarefaction of the air, for he no longer breathed, so to speak. We began at last to scale the last stage. We made ten steps and then stopped, finding it absolutely impossible to proceed. A painful contraction of the throat made our breathing exceedingly difficult. Our legs refused to carry us; and I then understood the picturesque expression of Jacques Balmat, when, in narrating his first ascent, he said that “his legs seemed only to be kept up by his trousers!” But our mental was superior to our physical force; and if the body faltered, the heart, responding “Excelsior!” stifled its desperate complaint, and urged forward our poor worn-out mechanism, despite itself. We thus passed the Petits-Mulets, and after two hours of superhuman efforts finally overlooked the entire chain. Mont Blanc was under our feet! [Illustration: Summit of Mont Blanc.] It was fifteen minutes after twelve. The pride of success soon dissipated our fatigue. We had at last conquered this formidable crest. We overlooked all the others, and the thoughts which Mont Blanc alone can inspire affected us with a deep emotion. It was ambition satisfied; and to me, at least, a dream realized! Mont Blanc is the highest mountain in Europe. Several mountains in Asia and America are higher; but of what use would it be to attempt them, if, in the absolute impossibility of reaching their summit, you must be content to remain at a lesser height? Others, such as Mont Cervin, are more difficult of access; but we perceived the summit of Mont Cervin twelve hundred feet below us! And then, what a view to reward us for our troubles and dangers! The sky, still pure, had assumed a deep-blue tint. The sun, despoiled of a part of his rays, had lost his brilliancy, as if in a partial eclipse. This effect, due to the rarefaction of the air, was all the more apparent as the surrounding eminences and plains were inundated with light. No detail of the scene, therefore, escaped our notice.
