Captain WiLKiNS is an experienced traveler both in the Arctic 

 and Antarctic. In the Canadian Arctic Expedition, 1913-1918, 

 he was second in command of Stefansson's part}^ (see Canadian Arc- 

 tic Expedition, Vol. 3: Report on Topographical and Geographical 

 Work, Ottawa, 191 7). He was also second in command of the 

 British Imperial Antarctic Expedition, 1920-192 1, and naturalist 

 on Shackleton's last expedition, 1921-1922. The following years 

 (1923-1925) he was leader of the Wilkins Australia and Islands 

 Expedition for the British Museum (Natural History). During 

 1926-1927, as commander of the Detroit Arctic Expedition, by his 

 airplane reconnaissance he made valuable additions to the knowl- 

 edge of hitherto unknown Alaskan regions, especially the Brooks 

 Range between the Yukon and the Arctic Coast. On March 29, 

 1927, he made the important sounding of 5440 meters in ']']° 45' 

 N. and 175° W., or about 330 miles north of Wrangel Island, making 

 the probability greater that the deep basin established by the 

 soundings of the Fram extends continuously across the Arctic Sea 

 to the Alaskan shore.
