I fear no contributions to science, or topography, or learning of any sort are to be found sandwiched in between the story of crags and séracs, of driving storm and perfect weather. To tell the truth, I have only the vaguest ideas about theodolites, and as for plane tables, their very name is an abomination. To those who think with me, who regard mountaineering as unmixed play, these pages are alone addressed. Should they, in some dim afterglow fashion, reflect the joy and frolic of sunshine holidays, their utmost mission will have been accomplished, and pride will mightily inflate their author.
My sincerest thanks are due to those friends who have so kindly placed drawings and photographs at my disposal; indeed, I feel that my debt to them is wholly beyond expression.
A. F. MUMMERY.
