Scale 1/100,000 " III Geological Map of the Mount Everest Region " INTRODUCTION BY SIR FRANCIS YOUNGHUSBAND, K.C.S.I., K.C.I.E. The idea of climbing Mount Everest has been vaguely in men's mind for thirty or forty years past. Certainly that veteran mountain-climber and mountain-lover, Douglas Freshfield, had it persistently rising within him as he broke away from the Swiss Alps and subdued the giants of the Caucasus and then sought still higher peaks to conquer. Lord Curzon also had had it in his mind, and when Viceroy of India had written suggesting that the Royal Geographical Society and the Alpine Club should make a joint exploration of the mountain. Bruce, Longstaff and Mumm would have made this exploration in 1905 if the permission of the Nepalese and Tibetan Governments had been available. So also would Rawling a few years later. All these, and doubtless others, had contemplated at least a preliminary reconnaissance of Mount Everest. But, so far as I know, the first man to propose a definite expedition to Mount Everest was the then Captain Bruce, who, when he and I were together in Chitral in 1893, proposed to me that we should make a glorious termination to a journey from Chinese Turkestan across Tibet by ascending Mount Everest. And it is Bruce who has held to the idea ever since and sought any opportunity that offered of getting at the mountain. It stands to reason that men with any zest for mountaineering could not possibly allow Mount Everest to remain untouched. The time, the opportunity, the money, the ability to make the necessary preliminary preparation might be lacking, but the wish and the will to stand on the summit of the world's highest mountain must have been in the heart of many a mountaineer since the Alps have been so firmly trampled under foot. The higher climbers climb, the higher they want to climb. It is certain that they will never rest content till the proudest peaks of the Himalaya are as subdued and tamed as the once dreaded summits of the Alps now are.
