Wiiteside, of the Section of Foreign Mineral 

 Reserves, presents the information received by 

 the Geological Survey up to February 15, 1922. 

 The tonnage of the countries not yet heard 

 from ordinarily amounts to 12 or 15 per cent. 

 of the total. Receipt of data for these missing 

 countries, estimates for which are included in 

 the total, may raise or lower the final figure by 

 some millions of tons. The unit used is the 

 metric ton of 2,205 pounds, the approximate 

 equivalent of the long or gross ton. It is not, 

 however, exactly the same, and the translation 

 from net or gross tons to metric tons gives 

 many of the figures an unfamiliar look. A 

 more complete report on world production in 

 1921 will be issued by the Geological Survey 

 about April 1. 



THE MOUNT EVEREST EXPEDITION 



We learn from the London Times that the 

 preparations for this year's Mount Everest 

 expedition are now complete. The nine mem- 

 bers who have left England for India are : 



Brigadier-General the Honorable C. G. Bruce, 

 C.B., chief of tfie expedition. 



Lieutenant-Colouel E. L. Strutt, C.B.E., D.S.O., 

 second in command. 



Mr. G. L. Mallory, who led the climbing party 

 in 1921. 



Mr. George Piueh, of the Imperial College of 

 Science. 



Major E. F. Norton, D.S.O., E.F.A. 



Mr. T. Howard Somervell, F.R.C.S., of Univer- 

 sity College Hospital. 



Dr. A. M. Wakefield, of Megantic, Quebec 

 Province. 



Dr. T. G. LongstafE, surgeon and naturalist. 



Captain J. B. L. Noel, M.G.C., photographic 

 officer. 



The party will be joined in India, the 

 Geographical Journal published by the Royal 

 Geographical Society states, by Captain Geof- 

 frey Bruce, Fifth Gurkhas, and by Captain 

 C. J. Morris, Third Q.A.O. Gurkhas. The 

 twelfth place was to have been filled bj' an 

 artist, but to the great disappointment of the 

 committee it was not possible to find one 

 among those whose methods seemed appro- 

 priate, who could undertake the journey. Of 

 the eleven members of the expedition named 

 above six are soldiers — three of the Gurkhas, 

 one of the Royal Scots, one Roj^al Field Artil- 

 lery, and one Machine Gun Corps, formerly of 

 the East Yorkshire Regiment. 



Three members of the party are of Cam- 

 bridge University — Mr. Mallory, of Magdalene, 

 Mr. Somervell, of Caius, and Dr. Wakefield, of 

 Trinity; two are of Oxford University — 

 Colonel Strutt and Dr. Longstaff, both of 

 Christ Church; three are surgeons; two are 

 naturalists, several are expert photographers, 

 one at least is a painter, and all are distin- 

 guished mountaineers. It is, in fact, a very 

 strong party, of which much is expected.
