“You’ll come to have a different notion of crevasses, sir,” he said, with a quiet smile, “after you’ve bin among the seracs of the Grand Mulet, and up some of the couloirs of Monte Rosa.”

“I doubt it not, Antoine,” said Lawrence, gazing with feelings of awe into a terrible split in the ice, whose beautiful light-blue sides deepened into intense blackness as they were lost to vision in an abyss, out of which arose the deep-toned gurgling of sub-glacial streams; “but you must not forget that this is quite new to me, and my feet are not yet aware of the precise grip with which they must hold on to so slippery a foundation.”

It was in truth no discredit to Lawrence that he felt a tendency to shrink from edges of chasms which appeared ready to break off, or walked with caution on ice-slopes which led to unfathomable holes, for the said slopes, although not steep, were undoubtedly slippery.

After much clambering, a ridge was at length gained, on which the second stake was set up, and then the party proceeded onwards to fix the third; but now the difficulties proved to be greater than before. A huge block of ice was fixed upon as that which would suit their purpose, but it stood like a peninsula in the very midst of a crevasse, and connected with the main body of ice by a neck which looked as sharp as a knife on its upper edge, so that none but tight-rope or slack-wire dancers could have proceeded along it; and even such performers would have found the edge too brittle to sustain them.

“You’ll have to show, Monsieur, some of your mountaineer skill here?” said the man who carried the stakes to Antoine.

He spoke in French, which Lawrence understood perfectly. We render it as nearly as possible into the counterpart English.

Antoine at once stepped forward with his Alpine axe, and, swinging it vigorously over his head, cut a deep notch on the sloping side of the neck of ice. Beyond it he cut a second notch. No man—not even a monkey—could have stood on the glassy slope which descended into the abyss at their side; but Antoine, putting one foot in the first notch, and the other in the second, stood as secure as if he had been on a flat rock. Again he swung his axe, and planted his foot in a third notch, swinging his axe the instant it was fixed for the purpose of cutting the fourth. Thus, cut by cut and step by step, he passed over to the block of ice aimed at. It was but a short neck. A few notches were sufficient, yet without an axe to cut these notches, the place had been absolutely impassable. It was by no means a “dangerous” place, according to the ideas of Alpine mountaineers, nevertheless a slip, or the loss of balance, would have been followed by contain death. Antoine knew this, and, like a wise guide, took proper precautions.

“Stay, sir,” he said, as Lawrence was screwing up his courage to follow him, “I will show you another piece of Alpine practice.”

He returned as he spoke, and, unwinding a coil of rope which he carried, fastened one end thereof round his waist. Allowing a few feet of interval, he then fastened the rope round Lawrence’s waist, and the assistants with the stakes—of whom there were two besides the man already referred to—also attached themselves to the rope in like manner. By this means they all passed over with comparative security, because if any one of them had chanced to slip, the others would have fixed the points of their axes and alpenstocks in the ice and held on until their overbalanced comrade should have been restored to his position.

On gaining the block, however, it was found that the line communicating with the theodolite on the one hand, and the Dook’s nose on the other, just missed it. The Professor’s signals continued to indicate “more to the left,” (his left, that is) until the stake-driver stood on the extreme edge of the crevasse, and his comrades held on tight by the rope to prevent him from falling over. Still the professor indicated “more to the left!”
