The American annual of photography . nder such conditions, was ap-parent. There was need for something more serviceable, andhe began work upon simplification. Out of the wreck of hisstudio in New Jersey, where flames destroyed a wonderfulcollection of 14 x 17 wet plate negatives, made all over theUnited States, and all his other equipment, he brought with himto New York a partly destroyed field glass. One side was 122 gone and it had been hung up as a relic of the old days, undis-turbed until the experiments to find a substitute for the cum-bersome telescope. The burned portion was then cut away andthe single barrel was left in its original optical efficiency. Bymeans of a piece of card-board, with a hole in it, the glass wasput in the regular camera and, to Mr. Elmendorfs great de-light and surprise, gave a beautiful image on the it came to making negatives there was image could not be made sharp, owing, partly, to the vibra-tion, and partly because the combination was not Detail of The Organ, included in the limits of the dottedsquare upon the full view. The huge rock formation is inac-cessible because of boiling water flowing in front of it. But these were things that, plainly, could be adjusted, andthe operator had the great satisfaction of realizing a combina-tion eight inches in length was to give him an image almost aslarge as his unwieldly telescope arrangement. He had but toproceed with the adjustments for the success that finally was a reduction in measurements only that was required,the principle remaining the same—a convex lens in front anda concave behind. The perfected outfits that may be pur-chased to-day are the same. He had been using a 4 x 5 six-inch focus rapid rectilinear lensfor his general work and he decided to fit an achromatic nega- 123 tive lens to it. He did his own grinding in converting an oldlens and produced an achromatic of one-inch focus. The com-bination was too powerful—t
