HILDEBRAND Assistant Editor, National Geographic Magazine ORGANIZED FOR "THE INCREASE AND DIFFUSION OF GEOGRAPHIC KNOWLEDGE" To carry out the purposes for which itwas founded fifty-nine years ago, the National Geographic Society publishes this Magazine monthly. All receipts are in vested in The Magazine itself or expended directly to promote geographicknowledge. Articles and photographs are desired. For material The Magazine uses, generous remuneration ismade. In addition to the editorial and photographic surveys constantly being made, The Society has sponsored more than loo scientificexpeditions, some of which required years of field workto achieve their objectives. The Society's notable expeditions have pushed back the historic horizons of the southwestern United States to a period nearly eight centuries before Columbus crossed the Atlantic. By dating the ruins ofthe vast communal dwellings inthat region, The Society's re searches solved secrets that had puzzled historians for three hundred years. In Mexico, TheSociety and the Smithsonian Institu tion, January 16, 1939, discovered the oldest work of man in the Americas for which we have adate. This slab of stone is engraved inMayan characters with adate which means November 4,291 B.c.(Spinden Correlation). It antedates by 200years anything heretofore dated in America, and reveals agreat center of early American culture, previouslyunknown. On November II,1935, inaflight sponsored jointly by the National Geographic Society and the U.S.Army Air Corps, the world's largest balloon, Explorer II,as cended to the world altitude record of72,395 feet. Capt. Albert W. Stevens and Capt. Orvil A.Anderson took aloft inthe gondola nearly aton of scientific instru ments, and obtained results of extraordinary value. The National Geographic Society-U. S.Navy Expe dition camped on desert Canton Island inmid-Pacific and successfully photographed and observed the solar eclipse of1937. The Society has taken part inmany projects toincrease knowledge ofthe sun. The Society cooperated with Dr. William Beebe indeep-sea explorations off Bermuda, during which aworld record depth of3,028 feet was attained. The Society granted $25,000, and inaddition $75,000 was given by individual members, to the Government when the congressional appropriation for the purpose was insufficient, and the finest ofthe giant sequoia trees inthe Giant Forest ofSequoia National Park ofCalifornia were thereby saved for the American people. One ofthe world's largest icefields and glacial systems outside the polar regions was discovered inAlaska and Yukon by Bradford Washburn while exploring for The Society and the Harvard Institute ofExploration, 1938.
