THE SUNDAY STAR. WASHINGTON, D. ¢, NOVEMBER 17, 1929—PART ONE. ~ CAMERA TO MAKE ANTARCTIC STRIP 1,600 Miles to Be Covered at Altitude of 1,000 to 10,000 Feet. BY RUSSELL OWEN. By Wireless to The_Star and the New York Times. LITTLE AMERICA, Anarctica, November 16.—The geological party has safely passed the crevassed Tegion lying across their route to the Queen Maud Mountains. A message to Comdr. Byrd from Dr. Gould last night said: “Came through broken area without mishap or adventure of any sort and camped for night well 1o the south. Hope our next crevasses will be at the mountains.” (Copyright, 1929, by the New York Times Co. and the & Louis Post-Dis- o patch. ~All rights for publication re- served throughout the world.)

It is Inlwn_vx rash to predict what may be done in exploration. The camera is aimed through holes in either side of the plane where canvas flaps have been made to fasten around' it to keep out the iey wind. Pictures will be made of one side of the route going out and of the other coming back if the same route is taken, and as they are taken at an angle they will cover & large territory. To Make Continuous Strip. The photographs will taken at 20 degrees from the horizontal and overlapped so as to give & con- tinuous strip from our base, which is on the coast, to the Scuth Pole, about 800 miles inland. Prom these photographs additions and verifications can be made on the existing line maps, or hand-drawn, and a photographic mosaic can be con- structed. The mosaic is made of overlapping photographs laid and pasted on & mount or base on which has been Con- trols may be defined as all data used to fix points on which to construct a mosaic or line map. ‘These data are always related to some | point located on the earth's surface and an exactly accurate survey cannot be made with it. The images on each photograph are matched with like images contained on the next photo- graphic strip, in this manner forming a composite picture of the entire area contained in the exposed film, The first picture of this long mosaic, we hope, will show the great Ice Bar- rler and Little America. ‘Then the strip starts across the barrier.

The aerial camera used on this flight |is the regulation United States Army Air Corps camera containing a long Toll of paper for recording data, a ther- mometer, a barograph and a stop- watch. Covers have been attached from the camera apertures in the plane to the | cover of the camera to keep out the | sub-zero air, which would otherwise come in at 100 miles an hour. These | | covers may keep the aerial surveyor from | | ending up with frozen hands, as most | of the work must be done without gloves. Convenient devices have been made in Little America to meet the unusual conditions under which the survey is made. Among them is & stand at- tached to the camera containing in- struments for recording data.

The camera weighs 34 pounds and is constructed of aluminum. It is made with the same precision as any other surveying instrument. The usual 12- inch focal length lens has been replaced by one of 915-inch focal length in order that the greatest coverage for the size of the exposed film can be obtained. Three extra rolls of film and a chang- ing bag are being carried in order that picturés can be taken on the return flight. This will make it possible to take 660 pictures during the flight.
