THE NATIONAL GEOGRAPHIC MAGAZINE UOfcial t'hotograph, U. b. Army Air Service ARROW ROCK DAM, ONE OF THE HIGHEST IN THE WORLD, EAST OF BOISE, IDAHO The normal flow of the river below this site is regulated by the streams shooting from the face of the dam. At the time that this photograph was made the summer needs had reduced the water in the reservoir, foot by foot. In the late spring melting snows on the mountains fill the reservoir again. At the near end of the dam is an emergency spillway, used to deflect water to an adjoining canyon when there is danger of its spilling over the center. secondary. I imagine that even now the majority of people who remember the event remember it entirely from the soup standpoint. On arriving at the speedway it was esti mated that the flight could be continued to Fort Benjamin Harrison, a military post, where far greater repair facilities could be obtained. But while flying over Indianapolis to the post the engine again began to heat very rapidly, a temperature of Io0° being reached. It became necessary to throttle down, with the result that the airplane was partly flown and partly glided to the Fort. A turn was made around the field to get the proper position to glide for a land ing. As we reached the edge of the field, the throttle was pulled back. The pro peller stopped, frozen tight by the heat of the engine! A good landing was made in the center of the field, and the pilots immediately jumped from the plane in order to avoid the danger of fire, which seemed probable, as a dense cloud of white smoke was pour ing from the engine. An automobile rushed out with fire-extinguishers.
