The party arrived early the same day at the Montagne de la Côte, where they passed the night. The next day, notwithstanding an increase of dangers and difficulties, they passed under the Dome de Gouté, and reached a platform, or small plain, at the height of 11,790 feet above the sea, where they pitched their tent in the snow, and passed the night. The following morning, (August 3d) the snow was so hard, and the ascent so steep, that they were compelled to cut their footsteps with a hatchet, and it was only by proceeding with the greatest caution, that they were enabled to pass this dangerous acclivity with safety. They, however, persevered, and reached the summit about an hour before noon, in view of many persons who were observing them from Chamouny. M. Saussure turned his eyes to the house where his mother and sisters were watching his progress with a telescope, and had the satisfaction of seeing the waving of a flag, which was the signal they had agreed to make, as soon as they should be assured of his safety. The latter part of his ascent was the slowest and most fatiguing, owing to the difficulty of breathing, occasioned by the rarity of the air: the stoutest of his guides could not take more than thirty steps, without stopping to take breath. No one had the least appetite, but all were much tormented by thirst. The guides pitched the tent, in which M. Saussure remained four hours, making a number of observations. At half after three, the party began to descend, and slept lower 1100 feet than the preceding night. The next day they arrived, without any accident, at Chamouny. This successful expedition of Saussure, and the interesting account he published of it, inspired many persons with a wish of accomplishing the same task; but they were generally soon deterred by an examination into the difficulties attending its execution, and returned satisfied with a view from the vallies below, of the terrific glaciers, and everlasting snows, which defend the approaches to the summit. The following are the principal attempts that have since been made, and it will be perceived that of these few, only a part have succeeded. On the 8th of August, 1787, five days after M. Saussure's return, Col. Beaufoy, an Englishman, set out from Chamouny for Mont Blanc, accompanied by ten guides. He reached the top the following day, and returned the third day to the village, with his face and eyes so inflamed, that he nearly lost his sight in consequence. As he was not properly provided with instruments, he was unable to add much to the observations which had been made by Saussure. He, however, determined the latitude of the summit to be 45°, 49´, 59´´.
