The chief part of this volume is occupied by the history of these attacks on the Matterhorn, and the other excursions that are described have all some connection, more or less remote, with that mountain or with Mont Pelvoux. All are new excursions (that is, excursions made for the first time), unless the contrary is pointed out. Some have been passed over very briefly, and entire ascents or descents have been disposed of in a single line. Generally speaking, the salient points alone have been dwelt upon, and the rest has been left to the imagination. This treatment has spared the reader from much useless repetition. In endeavouring to make the book of some use to those who may wish to go mountain-scrambling, whether in the Alps or elsewhere, prominence has been given to our mistakes and failures; and to some it may seem that our practice must have been bad if the principles which are laid down are sound, or that the principles must be unsound if the practice was good. The principles which are brought under the notice of the reader are, however, deduced from long experience, which experience had not been gained at the time that the blunders were perpetrated; and, if it had been acquired at an earlier date, there would have been fewer failures to record. My scrambles amongst the Alps were a sort of apprenticeship in the art of mountaineering, and they were, for the most part, carried out in the company of men who were masters of their craft. In any art the learner, who wishes to do good work, does well to associate himself with master workmen, and I attribute much of the success which is recorded in this volume to my having been frequently under the guidance of the best mountaineers of the time. The hints and observations which are dispersed throughout the volume are not the result of personal experience only, they have been frequently derived from professional mountaineers, who have studied the art from their youth upwards. Without being unduly discursive in the narrative, it has not been possible to include in the text all the observations which are desirable for the general reader, and a certain amount of elementary knowledge has been pre-supposed, which perhaps some do not possess; and the opportunity is now taken of making a few remarks which may serve to elucidate those which follow. When a man who is not a born mountaineer gets upon the side of a mountain, he speedily finds out that walking is an art; and very soon wishes that he could be a quadruped or a centipede, or anything except a biped; but, as there is a difficulty in satisfying these very natural desires, he ultimately procures an alpenstock and turns himself into a tripod. This simple implement is invaluable to the mountaineer, and when he is parted from it involuntarily (and who has not been?) he is inclined to say, just as one may remark of other friends, “You were only a stick—a poor stick—but you were a true friend, and I should like to be in your company again.”
