 tating prismatic plates. These plates are circular discs of polished glass, which overlap each other. The Night from the picture goes through the discs and is thrown on cell sensi- tive to light which changes the high lights. shadows and half tones of the picture into electrical vibrations, just as the human voice is changed into electrical vibrations by the transmitter of the telephone.
 Changed Into Pictures.
 These electrical vibrations are then impressed on radio carrier waves which broadcast them. At all receiving stations equipped with proper picture sets. these electrical vibrations are again changed into pictures.
 That is, the original picture is re- assembled on photographic plate, line by line. until the whole pie ture surface is covered. The picture is then developed and dried, and paper prints are made. This recre- ates the picture in duplicate of the original at the sending station.
 There can be as many photo- graphic plates as there are places where 1t is desired to receive these pictures"
 The simplicity of the operation was the most interesting feature of the historic occa sion, in the minds of those assembled to watch it. The receiving apparatus, contained in two large suitcases and trunk. ha0 been installed on the tenth story of the Bulletin building. It appeared like big camera: in fact, 1t was a camera divided in two parts, with the lens in Washington and the photographic plates in Philadelphia. Uses Auto Bulbs.
 On one of the box-like mechan- isms was a device made chiefly from an ordinary automobile headlight bulb. Something analogous to periscope was constructed on this, a vibrating mirror whose purpose was to reflect the photographic rays of light. Next a card was fitted over the lens in which hole had been drilled about as wide as pencil. A black hair was pasted lengthwise down the card. Two important fac- tors were that the hair had to be black and that it had to just pass oNtI the small opening.
 The little party of absorbed spec tators stood about the magical, yet simple appearing apparatus The room remained light. Soon little star was seen sparkling through the hole. It was o'clock and the navy men had started accomplishing the once impossible task of sending pie lures through the ether
 A set of prismatic plates began to rotate. The negative" was placed beyond them. Each of the party watched the star sparkle brighter and brighter The sharpness of the light set the air quivering and the quiver- ing cast a shadow upon the opening. The prismatic plates kept the ray of light moving slowly. It passed down the negative and continued to do so again and again in parallel lines, fraction of an inch apart. The DOT trait of President Harding was traced on the negative.
 There was a moment of tenseNsus- pense when the picture was taken from the machine and shown to the assembled party, relieved by feel ing of exultation when 1t was seen that the test had not failed and that the otograph-though imperfect was really recognizable. The imper- fections, according to Jenkins, the inventor. are due partly to the static" in the air and other atmos- pheric disturbances. and also to the fact that he has not yet been able to trap out" entirely ordinary radio transfers, some of which-in the form of code dots and dashes-imprint themselves on the negative.
 From the pictures which accom- pany the article it can be seen how the first impulses look as they are received on the negative-forming wavering lines across the surface. ITO make satisfactory picture touching up IS necessary. Jenkins claims that this fault will shortly be remedied and that even now, on short distances, he can secure perfect results. Adventurous Career.
 MT. Jenkins has had an adventur- ous career. He was born near Day ton. Ohio, August 22. 1868, went to Earlham college. a Quaker institu- tion in Richmond. and at the age ol l6 left home for the Oregon wheat fields. While there he became in-
