72 The Oologisls' Record, September i, 1922. 



" Whoever grasps at all the vast natural resources of the Polar 

 " lands and seas, and understands the conditions under which 

 " they are already beginning to be developed, will have fascinating 

 " dreams about any number of transarctic air routes destined to 

 " come into everyday use whenever air travel in general becomes 

 ' a commonplace on the more dangerous and difficult, but already 

 " speculatively accepted, routes between Liverpool and New York, 

 " San Francisco, Hawaii, and Japan." 



We hope our readers will not consider that we have strayed 

 too far from oological matters, but we have seldom seen a more 

 interesting and at the same time authoritative article on the future 

 possibihties of travel in the Polar regions, and of the chmatic and 

 other conditions which obtain there generally. 



Those who desire to read the article in its entirety should remit 

 54 cents by Money Order to the National Geographic Society, 

 Hubbard Memorial Hall, Washington, D.C., U.S.A., for the August 

 number of the Society's Magazine. The subscription for the year 

 is 4 dollars. Though the circulation of the magazine is certified 

 at 750,000 it is little known in this country.
