About this time also he returned with two of his companions, and placed on the top an obelisk of wood, twelve feet in height, (which they had brought up in pieces) to serve in the trigonometrical survey, that was then making of the country.
In 1812, M. Rodasse, a banker of Hamburgh, undertook and accomplished the same journey, without any accident.
The 16th of September, 1816, the Comte de Lucy, a Frenchman, succeeded, notwithstanding the severity of the cold he experienced, in attaining a rock only 600 feet lower than the summit of Mont Blanc. He was there, however, so entirely overcome with cold and fatigue, that he was unable to proceed this short distance, and compelled, with much reluctance, to return. On reaching the valley he was unable to walk, but was carried by his guides to the inn, where his feet proved to be so much frozen, that on drawing his boot, the skin peeled off and remained in it. Two of his guides were also severely frozen.
Count Malzeski, a Pole, left Chamouny the 5th of August, 1818, for Mont Blanc, accompanied by eleven guides, reached the summit the following day, and returned, in safety, the third, without suffering much more inconvenience than having his nose frozen.
During our visit to Chamouny, in the beginning of this month, my friend Dr. Van Rensselaer and myself, in our various excursions to the glaciers, and other scenes of the valley, had frequently opportunities of conversing with the guides, who had participated in these journeys, and among them with old Balmat, the Columbus of Mont Blanc. The result was, that our curiosity was strongly excited, and being induced by their representations of the almost certainty of succeeding in the present favourable weather, we finally determined, after much deliberation, to make the attempt. We therefore engaged Marie Coutet, an experienced guide, who had been three times on the summit, as leader, and eight other guides to accompany us. They refused to undertake the journey with a smaller party, on account of the number of articles which it was necessary to take with us, as a ladder, cords, provisions, charcoal to melt the snow for drinking, and a number of other things, which were indispensable, and which formed a sufficient quantity to load each of the nine with a considerable burthen. One day was occupied in making preparations, on which our comfort and our ultimate success depended. These were passed in review in the evening, and having found that nothing material was omitted, an early hour the next day was appointed for our departure.
Accordingly, on Sunday the 11th of July, we left the village of Chamouny, at five o'clock, full of anxiety ourselves, and accompanied by the good wishes of the honest inhabitants for our success. The necessity of taking advantage of the fine weather, opposed our delaying another day. Our guides, who in common with all the inhabitants of the mountainous parts of Savoy, are very attentive to the duties of their religion, were unwilling to set out on a church day, without having previously attended service. They had, therefore, induced the Curé to celebrate mass at three o'clock, and, notwithstanding the fatigue they expected during the day, the early hour had not prevented them from attending it.
We descended the valley by the side of the Arva, about a league, till we approached the glacier of Boissons, and then turning suddenly to the left into the woods, we began immediately a very steep ascent, parallel to, and about a half mile from the edge of the glacier. After about three hours toilsome mounting, we came to the last house on our road. It was the highest dwelling in the neighbourhood, and was one of those cottages called "Chalets," which are inhabited only during three of the summer months, when the peasants drive their cattle from the plains below, to the then richer verdure of the mountains. We found there the old man and his two daughters; his wife, as is the custom, was left behind to take care of the house in the valley. After refreshing ourselves with a delicious draught of fresh milk, and receiving the wishes of these good people, for a 'bon voyage,' we bade adieu to all traces of man, and continued to mount. Another hour's toil brought us above the region of wood, after which the few stinted vegetables we met with, gradually diminished in size, and when we arrived, at 10 o'clock, at the upper edge of the glacier of Boissons, only a few mosses, and the most hardy alpine plants were to be found.
We had been compelled a little before, by the precipices of the Aiguille du Midi, which presented themselves like a wall before us, to change our direction, and instead of proceeding parallel to the glacier, to strike off suddenly towards it. We had now a close view of some of the obstacles which bar the approach to Mont Blanc; the glacier of Boissons, on which we were about to enter, seemed to me absolutely impassable. The only relief to the white snow and ice before us, was an occasional rock, thrusting its sharp point above their surface, and too steep to permit the snow to lodge on it. One of these rocks, or rather a chain of them, called the 'Grand Mulet,' which we had destined for our resting place for the night, was before us, but far above our heads at the distance of four or five miles; the glacier, however, still intervened, and appeared to defy all attempts to approach it.
The glacier of Boissons, like all the glaciers of the Alps, is an immense mass of ice filling a valley which stretches down the mountain side, and is formed by the accumulated snow and ice, which are constantly in the summer months, falling from above. While the glaciers are thus continually increasing on the surface, the internal heat of the earth is slowly melting them below. Hence, when they are large, there generally proceeds from under them a considerable stream: such are the sources of the Rhine and of the Rhone. Their surface, often resembles that of a violent agitated sea, suddenly congealed. They are frequently of several leagues in breadth, and from 100 to 600 feet in depth. The snow which falls on them, to the depth of several feet every winter, is softened by the sun's rays in summer—and freezing again at the return of cold weather, but in a more solid state, forms a successive layer every year. This stratum may be easily measured, (as each of them is distinctly separated from its neighbour by a dark line,) at the section made by those cracks, which traverse every glacier in all directions. These cracks or crevices, are generally thought to be caused by the irregular sinking of part of the mass, whose support below has been gradually melted away. They are formed suddenly, and frequently with a noise that may be heard at the distance of several miles, and with a shock that makes the neighbouring country tremble: this effect takes place principally in summer. These rents are from a few inches to 20, 30, or even 50 or 60 feet in breadth, and generally of immense depth: probably extending to the bottom of the glacier. They present the greatest danger and difficulty to the passenger. They are often concealed by a layer of snow, which gives no indication on its surface, of its want of solidity; and it often happens that the chamois hunter, notwithstanding all his caution, suddenly sinks through this treacherous veil into the chasm beneath.
We remained a couple of hours at our resting place, to take some refreshment, and to regain strength for our next difficult task. Jacques Balmat accompanied us this far, to point out the best means of attaining that spot on which he was the first to set foot; but the infirmities of age prevented him from accompanying us farther. Our feet seemed to linger, and to leave with reluctance the last ground they were to touch until the period of our return.
