The people are asked to help the Signal Corps of the Army get lenses enough for cameras for the fleet of observation airplanes now being built. The need is immediate and of great importance. The lens is the eye of the Army.

The situation is that, American manufacturers are not yet in a position to meet the sudden demand for special lenses for aerial service. Possessors of the required types are, therefore, urged to do their bit by enlisting their lenses in the service of the Army. They are asked to immediately notify the Photographic Division of the Signal Corps, U. S. A., Mills Building Annex, Washington, D. C, of lenses of the following descriptions which they are willing to sell, stating price asked :

Tessar Anastigmat Lenses made by Carl Zeiss, Jena, of a working aperture of F. 3.5 or F. 4.5, from 8 1/4 to 20 inch focal length.

Bausch & Lomb Zeiss Tessars, F. 4.5t from 8 1/2 to 20 inch focal length.

Voigtlander Heliar Anastigmat Lenses, F. 4.5, 8 1/4 to 24 inch focal length.

Practically all of the lenses of these and other foreign makes of anastigmats in America will be required, but the 8 1/4 inch lenses are most urgently needed 8, 9, 12 and 14 inch condensers are wanted; also a number of Bausch & Lomb Zeiss Protars VII A No. 13, preferably set in Volute shutters.

(It is requested that the press and individuals giving publicity to the above give the specifications of the lenses desired accurately. This will avoid the labor and delay of unnecessary correspondence with people offering lenses that are unsuitable.)

Eastman School Of Professional Photography Temporarily Discontinued

During the past year the Eastman School has met with the greatest success of any year since its inception, and we are justly proud of its record. It is not our desire to curtail a plan of service to the professional photographer, of which we believe the Eastman School has become a very important part.

We must sooner or later, however, adapt ourselves to conditions made necessary by the preference given to shipments of food, supplies and munitions - conditions which the School had already begun to feel in its transportation problem.

Transportation has been one of the greatest problems of our Government, and transportation in all its forms must be conserved in every way possible. The School requires express transportation facilities for ten or twelve thousand pounds of apparatus, and as it has in the past been doing its "bit" to help the photographer, we feel that it must now do its "bit" to help the cause of the Nation, which is your cause and ours.After we win the war, the work of the School will be resumed. In the meantime, we ask you to put your problems up to our demonstrators, who are thoroughly competent and always willing to be of service to you. Give the demonstrator the opportunity to help you, and his fund of experience will prove of real value - will get you out of many a photographic difficulty.
