' l FOREST DALE POTATO CHIPS By ELMO SCOTT WATSON N MAY of last year the announcement was made that the United States army had added another brilliant achievement to the record which makes valid the boast that "the army does other things besides fight." A new record in long distance aerial photography had been set by the air corps of the army when Capt. A. W. Stevens, photographic expert, succeeded in taking a picture covering a distance of 270 miles in a single exposure. In 1929 Captain Stevens had f:et a long distance photographic record when his camera registered objects 227 miles away from the camera eye but his 1930 flight In a plane piloted by Lieut. Joiln D. Corkille over Crater lake in Oregon adc1ed more than 50 m'les to that record. Upon . his return from this flight, Captain Stevens declared "While I am very well satisfied with the results obtained on this particular mission, I am inclined to believe that It will only be a matter of time before we will develop 11. camera that will record even greater distances. Before we can use it, however, we must have a photographic plane that will take t.os considerably higher than 20,000 feet because from that altitude even an object as tall as Mount Rainier will sink below the horizon at SOO miles. "Shootfug at Mount Rainier from a distance greater than that between New York city and Washington Is much like shooting at the moon, with the difference that you can see the moo11. The principal task Is to aim the camera In the general direction yon believe your objective to be, snap the trigger and hope for luck." What "luck" the army captain had on this expedition was revealed by the remarkable photograph which is shown above. Another achievement ln this new scientific marvel of aerial photography, which was not so muck a matter of luck, was demonstrated during the army air maneuvers over New York city during May of this year, the resblts of which are shown in the photographs numbered three and four above, As explained In the captions, these pictures were taken by exploding a bomb containing enOUJl."h magnesium powder to make a 3,000,000.000 candlepower flash and snapping the shutter at the height of illumination. It would seem to be an easy matter to drop a flashlight bomb and !t the moment of the explosion to take the photograph. Since, however, there is a definite relationship between tile altitude of the airplane and the height at which the bomb explodes, it Is not so simple. Night photographs can be taken only at comparatively low altitudes. Measurements of the pbotograpb·s taken over New York showed the airplane to have been flying at only 1,500 ft>et. although night photographs could be taken effecti>ely up to around 3,000 feet. The lens cannot be left open until the bomb explodes because lights from the ground would blur the plates or film. The only thing the air camera man has to rlo at night ls to release the bomb; the rest of the details are taken care of automatically. 'l'he bomb, containing twenty-five pounds of magnesium powc1er, Is checl;ed in its fall by a small parachute and a time fuse sets the interval from the release to the e::~.""[)losion. As the bomb bursts the camera's shutter is automatically tripped by an ingenious mechanical device. Before the World war the science of aerial photography, except for a few cases, most of which were unsuccessful, was virtually unknown. It took on added Importance early In the war and developed rapidly as the airplane bt>came su<:h an important factor in waging sue<:e~sful battles.

Two hundred and seventy miles of wide open spaces! A photograph of Mount Rainier takeu from over Crater lake, a distance of 270 miles, by Capt. Albert W. Stevens from <an army air corps plane piloted by Lieut. John D. Corkifle. To get the "shot," the two army airmen flew at 20,000 feet for nearly five hours in a temperature of 20 degrees below zero and came down only when their supply of liquid oxygen was exhausted. Some of the mountains shown In the picture are: 1. Mount Rainier, 270 miles; 2. Mount Hood, 200 miles; 3. Mount Jefferson, 175 miles; 4. Three Sisters, 125 miles; 5. Diamond Peak, 50 miles; Crescent Lake, 45 miles. 2. Captain Stevens and Lieutenant Corkille of the United States army air corps with the large aerial camera used in taking high altitude photographs. This camera uses a 30-inch focal length lens of special construction. 3. This night photograph of lower Manhattan, New York city, was taken by Captain Stevens from an airplane piloted by Lieutenant Corkille at an altitude of about 1,500 feet.. A bomb containing sufficient flashlight powde<r for a three billion candlepower flash was dropped from the plane and the picture taken with a specially constructed camera equipped with an automatic device for exposing the film at the heioht of illumination. 4.

All photographs, courtesy United States Army Air corps. • • been carried forwai"d mainly by the United States army. Although the ai"my Is chiefly interested In map-mal,lng and intelligence photography, each of which requires a different technique, it has many times sent Its camera men and planes to C{I-Operate with other governmen-t agencies. The army has Indirectly aided commercial aerial photography by developing the best in technique and in precision of the instruments. In addition to military work, aerial surveys are used for a farge variety of operations. Few public utility companies would consider putting down a new power line without first having an aerial survey made. Aerial photography ls also in demand for forestry services, geological surveys, harbor developments, highway and traffic surveys, and all manner of city uses, from · planning and zoning to tax equalization. The cameras and equipment used for civil aerial surveying and for the proc1uction of aerial photographs as illustrations have been improved but little during the last ten years, because the ordinary nir camera, operated at relatively low altitudes, meets all usual requirements at a small cost. This is not the case with wili t11ry photography, and so it is In this branch that the latest developments are found. Perhaps the most interesting development lie!. in the use of long-range or high-altitude cameras, the same technique being used also f(}r lower altitude work through fog. In high alti· tude work the camera must have a long focal length (the distance from the nodal pointwhere the light rays cross, between the two lenses-to the surface of the plate or film), With a short focal length it would be possible for the camera to "take the whole world," but the (letail would be too small. A camera with a long focal length, on the other hand, while it w~ll not take more than about thirty-three square miles from an altitude of approximately 33,000 feet, gives such clearness of detail that the negatives may be readily enlarged to ten diameters. If 'the camera is tilted an oblique photograph ls taken-that is, a photograph which ts progress! vely distorted as the objects taken are distant from the lens. Tremendous distances have been covered in this way and objects have been taken which were not visible to the naked eye, because aloft there is almost always, even on a clear day, a certain amount of greund haze. Several ·refinements are necessary, however, before these photographs may be taken. The camera must be fitted with a special film sensi· tive only to infra-red rays below the visible spectrum-that is, the long wave lengths which go through fog easily. This condition Is met by taking ordinary gelatine film and Immersing it in a sblution of kryptocyanine. The next requisite is a special type of filter, so dense as to have the opaqueness of rubber. All lenses have to a greater or less extent the property of a prism; that is, they break up the white light Into spectra. It is necessary under given conditions to use a filter to eliminate the active colors ( such as violets, blues and greens) and restore the light to white. By Increasing the opaqueness of the filter more "'f the visible spectrum is eliminated, and it !s possible to eliminate it altogether. This is what has been done in tbe cast of the long-range camera. Thro11gh its filter only the infra-red rays are admitted, and as ground haze or smoke ls no obstacle to them, obje<:ts are recorded on the film which are invisible to the naked eye. In this way Captain Stevens was able to photograph Mount Rainier from the record distance of 270 miles, the peak jutting up above the horizon, though It was miles beyond it. In th~:j taking of photographs for map-making a special tec-hnique has had to be developed, equally applicable to military and commercial purposes. It Is not enough to sight the camera and ti"ip it; all sorts of things have to be de· termined before the photograph can be taken. Because only the center of each photograph can be considered anything like optically perfect, a large number of overlapping exposures have to be made. (Ill) bY Western NewspaJ:>~r Union.)

It is namC1'1 from the Fleet river. In the early chronicles of London many allusions are made to the deeds of violence done in this street. By the time of Elizabeth it had become a favorite spot for shows and processions. It was noted formerly for its travens and coffee houses, frequented by many persons of literary fame. It is now the chief center of British journalism. "Racket's" Origin The word "r3;cket" with the meaning of confused, clattering noise, has an imitative origin etymologically. By extension this came to mean a social bustle of some kind, with a meaning similar to the word ''sp1•ee." Finally by the uncertain processes which such words often take, it came to have a slang meaning of a scheme, dodge or trick.
