It is scarcely necessary to observe, after what was said upon p. 116, that it is my invariable practice to employ a rope when traversing a snow-covered glacier. Many guides, even the best ones, object to be roped, more especially early in the morning when the snow is hard. They object sometimes, because they think it is unnecessary. Crevasses that are bridged by snow are almost always more or less perceptible by undulations on the surface; the snow droops down, and hollows mark the courses of the chasms beneath. An experienced guide usually notices these almost imperceptible wrinkles, steps one side or the other, as the case may require, and rarely breaks through unawares. Guides think there is no occasion to employ a rope because they think that they will not be taken by surprise. Michel Croz used to be of this opinion. He used to say that only imbeciles and children required to be tied up in the morning. I told him that in this particular matter I was a child to him. "You see these things, my good Croz, and avoid them. I do not, except you point them out to me, and so that which is not a danger to you, is a danger to me." The sharper one's eyes get by use, the less is a rope required as a protective against these hidden pitfalls; but, according to my experience, the sight never becomes so keen that they can be avoided with unvarying certainty, and I mentioned what occurred upon the Otemma glacier to show that this is so.
I well remember my first passage of the Col Theodule—the easiest of the higher Alpine glacier passes. We had a rope, but my guide said it was not necessary, he knew all the crevasses. However, we did not go a quarter of a mile before he dropped through the snow into a crevasse up to his neck. He was a heavy man, and would scarcely have extricated himself alone; anyhow, he was very glad of my assistance. "When he got on to his legs again, he said, "Well, I had no idea that there was a crevasse there!" He no longer objected to use the rope, and we proceeded; upon my part, with greater peace of mind than before. I have crossed the pass thirteen times since then, and have invariably insisted upon being tied together.
