Organized for “The Increase and Diffusion of Geographic Knowledge” 
TO carry out the purposes for which it was founded 
thirty-six years ago, the National Geographic 
Society publishes the National Geographic Magazine. All 
receipts are invested in the Magazine itself or expended directly 
to promote geographic knowledge. 
ARTICLES and photographs are desired. For 
material which the Magazine can use, generous 
remuneration is made. Contributions should be accompanied 
by an addressed return envelope and postage. 
IMMEDIATELY after the terrific eruption of the 
world’s largest crater, Mt. Katmai, in Alaska, a 
National Geographic Society expedition was sent to make 
observations of this remarkable phenomenon. Four expeditions 
have followed and the extraordinary scientific data resultant 
given to the world. In this vicinity an eighth wonder of the 
world was discovered and explored—“The Valley of Ten Thou¬ 
sand Smokes,” a vast area of steaming, spouting fissures. As a 
result of The Society’s discoveries this area has been created 
a National Monument by proclamation of the President of the 
United States. 
AT an expense of over $50,000 The Society sent a 
notable series of expeditions into Peru to investigate 
the traces of the Inca race. Their discoveries form a large 
share of our knowledge of a civilization waning when Pizarro 
first set foot in Peru. 
THE Society also had the honor of subscribing a 
substantial sum to the expedition of x'\dmiral Peary, 
who discovered the North Pole. 
NOT long ago The Society granted $25,ocx), and in 
addition'$75,ooo was given by individual members 
to the Government when the congressional appropriation for the 
purchase was insufficient, and the finest of the giant sequoia 
trees of California were thereby saved for the American people. 
THE Society is conducting extensive explorations 
and excavations in northwestern New Mexico, which 
was one of the most densely populated areas in North America 
before Columbus came, a region where prehistoric peoples lived 
in vast communal dwellings and whose customs, ceremonies, 
and name have been engulfed in an oblivion. 
THE Society also is maintaining expeditions in the 
unknown area adjacent to the San Juan River in 
southeastern Utah, in Yunnan, Kweichow, and Kansu, China, 
at Carlsbad Caverns in New Mexico, probably the largest cave 
yet discovered in America, and at Cuicuilco, Mexico, where the 
relics of inhabitants of America 7,000 years ago are being 
revealed.
