McKNEW Secretary National Geographic Society ORGANIZED FOR "THE INCREASE AND DIFFUSION OF GEOGRAPHIC KNOWLEDGE" To carry out the purposes for which it was founded sixty- five years ago, the National Geographic Society publishes The National Geographic Magazine monthly. All receipts are in- vested in The Magazine itself or expended directly to promote geographic knowledge. Articles and photographs are desired. For material The Magazine uses, generous remuneration is made. In addition to the editorial and photographic surveys con- stantly being made, The Society has sponsored more than 100 scientific expeditions, some of which required years of field work to 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 of the vast communal dwellings in that region, The Society's researches solved secrets that had puzzled historians for three hundred years. In Mexico, The Society and the Smithsonian Institution, January 16, 1939, discovered the oldest work of man in the Americas for which we have a date. This slab of stone is en- graved in Mayan characters with a date which means Novem- ber 4, 291 B. c. (Spi nden Correlation). It antedates by 200 years anything heretofore dated in America, and reveals a great center of early American culture, previously unknown. On November 11, 1935, in a flight sponsored jointly by the National Geographic Society and the U. S . Army Air Corps, the world's largest balloon, Explorer II, ascended to the world altitude record of 72 ,395 feet. Capt. Albert W. Stevens and Capt. Orvil A. Anderson took aloft in the gondola a ton of scien- tific instruments and obtained results of extraordinary value. A notable undertaking in the history of astronomy was launched in 1949 by The Society in cooperation with the Palomar Observatory of the California Institute of Technology. This project will require four years to photomap the vast reaches of space, and will provide the first sky atlas for observa- tories all over the world. In 1948 The Society sent seven expeditions to study the Sun's eclipse on a 5,320-mile arc from Burma to the Aleutians. The National Geographic Society and the Royal Ontario Museum in 1951 explored and measured newly found Chubb meteor crater, 11,500 feet in diameter, in northern Quebec. The Society granted 25,000, and in addition $75,000 was contributed by individual members, to help preserve for the American people the finest of the giant sequoia trees in the Giant Forest of Sequoia National Park of California. One of the world' largest icefields and glacial systems out- side the polar regions was discovered in Alaska and Yukon by Bradford Washburn while exploring for The Society and the Harvard Institute of Exploration, 1938.
