Excerpt: 'Colonel Howard-Bury and the members of the Expedition of 1921 had effected the object with which they had been despatched. They were not sent out to climb Mount Everest. It would be impossible to reach the summit in a single effort. They were sent to reconnoitre the mountain from every direction and discover what was for certain the easiest way up. For it was quite certain that only by the easiest way possible-and only if there were an easy way-would the summit ever be reached. In the Alps, nowadays, men look about for the most difficult way up a mountain. Hundreds every year ascend even the Matterhorn by the easiest ways up. So men with any turn for adventure have to look about for the difficult ways. With Mount Everest it is very different. The exhaustion produced from the difficulty of breathing in enough oxygen at the great heights is so fearful that only by a way that entails the least possible exertion can the summit be reached. Hence the necessity for spending the first season in thoroughly prospecting the mountain. And this was all the more necessary because no European so far had been within sixty miles of Mount Everest, so that not even the approaches to the mountain were known.'
