Two Pamphlets from Power The Nicholas Power Co., at 90 Gold St., New York City, have prepared two booklets for free distribution which are very valuable to all users of projection equipment, either for slides or for moving pictures, and with any make of machine. The first pamphlet is called "The Edison Mazda Lamp in Motion Picture Projection," and was compiled by the staff of the Edison Lamp Works at Harrison, N. J. This pamphlet points out the advantages of Mazda Lamps for projection service; covering the cost of operation and field of application, as well as types of lamps available. It gives in detail the optical set-up for the Edison Mazda Lamp, with instructions for its installation and maintenance. The pamphlet also contains data on motion picture screens, their reflection characteristics and maintenance; the general characteristics of Edison Mazda Lamps, such as the functioning of the gas, variation in candlepower and life; blackening of the bulbs, reason for 30 volt vs. 110 volt lamps, etc. Also some data on control equipment, theatre lighting, and testimonials from satisfied customers. The second pamphlet is called "Power's Improved Projector with Incandescent Equipment," and serves admirably to supplement the other pamphlet by showing the application of the Mazda principle to actual projectors and stereopticons. It explains in detail the placing of lamp, reflector condenser, etc., and is full of suggestive helps on installation problems. The Nicholas Power Co. has devised various forms of unit equipment for incandescent lighting to meet varied demands, and these are designed for use not only with machines of their own make but for other standard makes as well. These two pamphlets are of certain value to any worker in the projection field, whether on a large or small scale, and they will be mailed free on request. A Special Service to Educators Every State University and Board of Education recognizes the advantages of owning prints of motion pictures for distribution throughout their school systems, over and above the plan of daily rental from exchanges. During the past we have received many requests for the sale of Pathe subjects suited to school and community use. We are quite cognizant of, and sympathetic with, the advantage of ownership of prints, but we are faced with the necessity of protecting a product so easily lost and so frequently stolen as positive and negative motion picture film. After much consideration, we have evolved a plan that gives the educational group every prerogative of ownership, while it enables us to protect our product. Any authorized educational body may lease Pathe Pictures for a period of three years on condition that the print is returned to us at the end of that period of time. This offer is for new prints from the laboratory, not prints that have seen use, and it includes all Pathe subjects. For details of price and contractual terms, write to The Educational Department, Pathe Exchange, Inc., 35 West 45th Street, New York City.
