The industry has been 100 per cent cooperative in following the request of War Mobilization and Reconversion Director James F. Byrnes, and it is interesting to note also that management and labor have been vocal only in statements that they will cooperate in the spirit as well as the actual letter of the request. Sadly, this cannot be said of the entire entertainment world, apparently not fully realizing that One World War is being fought that demands sacrifices on the home front as well as the combat areas. For our part we believe that the boys on fwo and the other millions in the other horrid wonderlands of Mars would pass the ammunition even a little more willingly if they knew they could call it a day at curfew hour. The movie world's war record has been unblemished to date and it is to be hoped that not even one small black spot will mar it during the curfew era, through neglect or otherwise. Projectionists, of course, can police their own houses, and see to it that the show is over in time to sound the "all clear" at curfew. Things should be clearer also for those who study the initial article in this issue on 16-mm projectors by Aaron Nadell, editor-on-leave. Mr. Nadell has taken apart a 16-mm projector thoroughly and with words and illustrations, endeavored to clear up some of the fog that has mantled this field in so far as projectionists for regulation equipment are concerned. This is only the beginning of I. P.'s educational series, and from time to time additional articles will "tell all" about other projectors. Due to paper shortages extra copies will not be available, which is a hint that those who want to study the articles from time to time should see to it that they are filed away for reference. March is Red Cross Month, according to Presidential proclamation. It is needless to mention each year the tremendous work "the helping hand" of this organization achieves, nor its need for donations, even though all of its activities are financed through voluntary contributions. This is as much a "must" as is the purchase of War Bonds, and that little extra that may be donated during the latter part of the drive, after you have already done more than your part, may be just the bit in cumulative form that will save extra lives, bring cheer to the families of those in the armed services, or make it easier for civilians who are victims of disaster.
