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 resulting given to the world. In this vicinity an eighth wonder of the world was discovered and explored-"The Valley of Ten Thousand 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 Admiral Peary, who discovered the North Pole. NOT long ago The Society granted $25.000, and in addition $75,000 was given by individual members to the Government when the congressional appropriation for the purpose 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. TO further the important study of solar radiation in relation to long-range weather forecasting, The Society has appropriated $60,000 to enable the Smithsonian Institution to establish a station for four years on Mt. Brukkaros, in Southwest Africa. Copyright, 1927, by National Geographic Society, Washington, D. C.. in the United States and Great Britain. All rights reserved.

Allover the World, wherever Great Governments hold official accuracy tests, Longines has swept the field. And because Longines are as beautiful as they are accurate, they are chosen by men and womenwho desire the ultimate of watchmakers' craftsmanship.
