I cannot close this chapter without paying a tribute to the ability with which Croz led us through a dense mist down the remainder of the Glacier de Pilatte.

As an exhibition of strength and skill it has probably never been surpassed in the Alps or elsewhere. On this almost unknown and very steep glacier he was perfectly at home, even in the mists. Never able to see fifty feet ahead, he still went on with the utmost certainty and without having to retrace a single step, and displayed from first to last consummate knowledge of the materials with which he was dealing. Now he cut steps down one side of a sérac, went with a dash at the other side, and hauled us up after him; then cut away along a ridge until a point was gained from which we could jump on to another ridge; then, doubling back, found a snow-bridge, across which he crawled on hands and knees, towed us across by the legs, ridiculing our apprehensions, mimicking our awkwardness, declining all help, bidding us only to follow him.

About 1 P.M. we emerged from the mist, and found ourselves just arrived upon the level portion of the glacier, having, as Reynaud properly remarked, come down as quickly as if there had not been any mist at all. Then we attacked the leg of mutton which my friend had so thoughtfully brought with him, and afterward raced down, with renewed energy, to La Bérarde.

Reynaud and I walked together to St. Christophe, where we parted. Since then we have talked over the doings of this momentous day, and I know that he would not, for a good deal, have missed the passage of the Col de Pilatte, although we failed to make it an easier or a shorter route than the Col du Selé. I rejoined Moore and Walker the same evening at Venos, and on the next day went with them over the Lautaret road to the hospice on its summit, where we slept.

So our little campaign in Dauphiné came to an end. It was remarkable for the absence of failures, and for the ease and precision with which all our plans were carried out. This was due very much to the spirit of my companions, but it was also owing to the fine weather which we were fortunate enough to enjoy, and to our making a very early start every morning. By beginning our work at or before the break of day on the longest days in the year, we were not only able to avoid hurrying when deliberation was desirable, but could afford to spend several hours in delightful ease whenever the fancy seized us.

I cannot too strongly recommend tourists in search of amusement to avoid the inns of Dauphiné. Sleep in the châlets. Get what food you can from the inns, but by no means attempt to pass a night in them. Sleep in them you cannot. M. Joanne says that the inventor of the insecticide powder was a native of Dauphiné. I can well believe it. He must have often felt the necessity of such an invention in his infancy and childhood.

CHAPTER XI.
PASSAGE OF THE COL DE TRIOLET, AND ASCENTS OF MONT DOLENT, AIGUILLE DE TRÉLATÊTE AND AIGUILLE D’ARGENTIÈRE.

Ten years ago very few people knew from personal knowledge how extremely inaccurately the chain of Mont Blanc was delineated. During the previous half century thousands had made the tour of the chain, and in that time at least one thousand individuals had stood upon its highest summit; but out of all this number there was not one capable, willing or able to map the mountain which, until recently, was regarded as the highest in Europe.

Many persons knew that great blunders had been perpetrated, and it was notorious that even Mont Blanc itself was represented in a ludicrously incorrect manner on all sides excepting the north; but there was not, perhaps, a single individual who knew, at the time to which I refer, that errors of no less than one thousand feet had been committed in the determination of heights at each end of the chain, that some glaciers were represented of double their real dimensions, and that ridges and mountains were laid down which actually had no existence.

One portion alone of the entire chain had been surveyed, at the time of which I speak, with anything like accuracy. It was not done (as one would have expected) by a government, but by a private individual—by the British De Saussure, the late J. D. Forbes. In the year 1842 he “made a special survey of the Mer de Glace of Chamounix and its tributaries, which in some of the following years he extended by further observations, so as to include the Glacier des Bossons.” The map produced fror this survey was worthy of its author, and subsequent explorers of the region he investigated have been able to detect only trivial inaccuracies in his work.
