“We had accomplished in safety a distance of scarcely more than 150 yards when, as I was looking at the Jungfrau, my attention was attracted by a sudden exclamation from Victor, who appeared to stagger and all but lose his balance. At first, the idea of some sort of seizure or an attack of giddiness presented itself, but, without stopping to enquire, I at once turned round, drove my good 8-foot ash-pole as deeply as possible through the surface layer of fresh snow into the firmer stratum beneath, tightened the rope to give Victor support, and shouted to Peter to do the same. All this was the work of an instant, and a glance at once showed me what had happened. Victor was safe for the moment, but a layer or couche of snow, 10 inches to a foot in thickness, had given way exactly beneath his feet, and first gently, and then fleet as an arrow, went gliding down, with that unpleasant sound somewhat resembling the escape of steam, which is so trying to the nerves of the bravest man, when he knows its full and true significance. At first a mass 80 to 100 yards in breadth and 10 or 15 in length alone gave way, but the contagion spread, and ere another minute had elapsed the slopes right and left of us for an extent of at least half a mile, were in movement, and, like a frozen Niagara, went crashing down the ice-precipices and séracs that still lay between us and the Aletsch glacier, 1800 to 2000 feet below. The spectacle was indescribably sublime, and the suspense for a moment rather awful, as we were clinging to an incline at least as steep as that on the Grindelwald side of the Strahleck—to name a familiar example—and it was questionable whether escape would be possible, if the layer of snow on the portion of the slope we had just been traversing should give way before we could retrace our steps.

“Not a moment was to be lost; no word was spoken after the first exclamation, and hastily uttered, ‘Au col! et vite!’ and then in dead silence, with bâtons held aloft like harpoons, ready to be plunged into the lower and older layers of snow, we stole quietly but rapidly up towards the now friendly-looking corniche, and in a few minutes stood once more in safety on the ridge, with feelings of gratitude for our great deliverance, which, though they did not find utterance in words, were, I believe, none the less sincerely felt by all of us. ‘Il n’a manqué que peu à un grand malheur,’ quietly remarked Victor, who looked exhausted, as well he might be after what he had gone through; but a goutte of cognac all round soon set us right again, and shouting to Bennen, who was still in sight, though dwindled in size to a mere point, we were soon beside him, running down the névé of our old friend, the Aren Glacier. The snow was now soft and the heat tremendous, and both Bennen and Bohren showed signs of fatigue; but a rapid pace was still maintained in spite of the frequent crevasses. Some were cleared in a series of flying leaps, whilst into others which the snow concealed, one and another would occasionally sink, amid shouts of laughter from his companions, who, in their turn, underwent a similar fate. To the carefully secured rope, which, with the alpenstock and ice axe, are the mountaineer’s best friends, we owed it that these sudden immersions were a mere matter of joke; but even the sense of security which it confers does not altogether prevent a ‘creepy’ sensation from being experienced, as the legs dangle in vacancy, and the sharp metallic ring of the icy fragments is heard as they clatter down into the dark blue depths below.”

The higher and more snow-laden the mountain chain, the more risk is there from avalanches. It seems practically certain that Mr Mummery met his death in the Himalayas from an avalanche, and that Messrs Donkin and Fox and their two Swiss guides perished in the Caucasus from a like cause. Sir W. Martin Conway, in his book on the Himalayas, makes several allusions to avalanches, and on at least one occasion, some members of his party had a narrow escape. He relates the adventure as follows:
