45 Mr. Hawkins referred to this place as one of excessive difficulty. He, however, found it coated with ice; we found it free from ice. 46 I learned afterwards from Jean-Antoine Carrel that they got considerably higher than upon their previous attempts, and about 250 or 300 feet higher than Professor Tyndall in 1860. In 1862 I saw the initials of J. A. Carrel cut on the rocks at the place where he and his comrade had turned back. 47 This man proved to be both willing and useful on lower ground, and voluntarily accompanied me a considerable distance out of his way, without fee or reward. _ 48 Alpine Journal_, 1863, p. 82. 49 See p. 49. _ 50 Mountaineering in 1861_, pp. 86-7. Tyndall and Bennen were mistaken in supposing that the mountain has two summits; it has only one. They seem to have been deceived by the appearance of that part of the south-west ridge which is called “the shoulder” (l’épaule), as seen from Breil. Viewed from that place, its southern end has certainly, through foreshortening, the semblance of a peak; but when one regards it from the Col Théodule, or from any place in the same direction, the delusion is at once apparent. 51 The late Principal Forbes was similarly situated while crossing the same pass in 1842. He described the sounds as rustling, fizzing, and hissing. See his _Travels in the Alps of Savoy_, second ed., p. 323. Mr. R. Spence Watson experienced the same upon the upper part of the Aletsch glacier in July 1863, and he spoke of the sounds as singing or hissing. See the _Athenæum_, Sept. 12, 1863. The respective parties seem to have been highly electrified on each occasion. Forbes says that his fingers “yielded a fizzing sound;” and Watson says that his “hair stood on end in an uncomfortable but very amusing manner,” and that “the veil on the wide-awake of one of the party stood upright in the air!” 52 I have described this tent at length, as frequent application has been made to me for information on the subject. I would strongly recommend any person who wishes to have one for long-continued use, to have one made under his own eye, and to be particularly careful to test the poles. My experience goes to show that poles which (when supported upon their extremities) will bear a dead weight of 100 lbs. suspended from their centres, will stand any wind to which they are likely to be submitted. Ash is, perhaps, the best wood that can be selected. Tents of this pattern have been used, amongst others, by Messrs. Freshfield, Moore, and Tucker, in the Caucasus; by the Rev. W. H. Hawker in Corsica; and by myself in Greenland.
