To overcome this lack, which is believed by many to be one of the serious drawbacks to the more rapid spread of motion picture work in schools, the Acme Motion Picture Projector Company has prepared an excellent booklet which gives complete instructions for the use and care of their Acme S. V. E. combination motion picture projector and stereopticon. This booklet shows careful and intelligent effort. By making generous use of simple diagrams and photographs to illustrate the various operations, the .^cme Company has succeeded in producing a set of instructions which are so easy to understand that anyone can learn to operate and care for the Acme S. V. E. by following the suggestions given. One of the distinctive features of the Acme Projector is that each operating button is outside the case of the machine, and plainly labeled to show its function. This labeling of operating controls is a great aid to the novice. The new instruction book is useful not only to the novice, but also to the more experienced operator; in addition to instructions for the operation and care of the machine, the book contains suggestions on the care of film, and other hints useful to projector users. A copy of "How to Operate the Acme S. V. E. Type F Semi-Portable Motion Picture Projector" is sent with each machine shipped from the Acme factory. The company will be glad to send one of the books to anyone interested who has not already received a copy. It is understood that the Acme Company is preparing a similar booklet for use with the Model 12 Acme Portable Projector, a suitcase style machine which has become very popular among those who require machines of that type.
