Mount Everest the Reconnaissance, 1921 by Charles Kenneth Howard-Bury, George H. Leigh-Mallory, A. F. R. Wollaston

The Mount Everest Committee of the Royal Geographical Society and the Alpine Club desire to express their thanks to Colonel Howard-Bury, Mr. Wollaston, Mr. Mallory, Major Morshead, Major Wheeler and Dr. Heron for the trouble they have taken to write so soon after their return an account of their several parts in the joint work of the Expedition. They have thereby enabled the present Expedition to start with full knowledge of the results of the reconnaissance, and the public to follow the progress of the attempt to reach the summit with full information at hand.
