The Lake District is becoming more popular every year as a centre of operations for cragsmen. Yet there is no corresponding development of a set of professional guides out there, though I believe they would thrive exceedingly, and all stock information about the mountains is confined to a few manuscript books, and to Mr. Haskett Smith’s little publication already referred to. The new comer is continually at a loss for details; he has no means of learning what is difficult or easy, how to circumvent dangerous obstacles or to discover the safe points of attacking them; he is dependent for such facts on chance acquaintances made in the country or on correspondence more or less painfully elicited from authorities. When unsuccessful in these ways he is sometimes tempted to launch out on his own account and wrest the information from the mountains themselves. This heroic method is undoubtedly the most effective, but it involves too much risk for the unpractised hand, and the wonder is that so few serious casualties occur in its application. Such accidents do occur through ignorance of the district, and always will so long as the necessary knowledge that gives safety to the explorer is confined to the few. Mr. Haskett Smith’s book serves in the fullest manner to indicate where good scrambling can be obtained, to define the few technical terms in the cragsman’s vocabulary, and to give general advice concerning the best centres. It has been of the greatest use to the climbing fraternity, who owe their thanks to him. But he gives no detail of the scrambling itself. He has appealed more particularly to the expert, who can manage all his pioneering for himself. Notably is this the case with the Pillar Rock--practically his own particular preserve--where most of the routes have long since been made out by him. For years he knew the Rock as no one else knew it; every chimney and ridge and wall was within his ken. Yet in his little handbook there is scarcely an indication of the possession of all this unique knowledge. Most climbers expected some expansion in the description of his early explorations; but he has kept rigidly to his scheme of treatment, and dealt but scant justice to himself throughout the work. This book, then, is to be regarded in some sense as supplementary in character, the cordial witness of the good sport obtainable by following his advice and general directions.
