MONTHLY CHAT THIS month we offer great gobs of very readable and very valuable information. The best variety of ye olden vaudeville show hasn't a thing on us, as even a casual perusal of our pages will prove. Which is exactly as it should be and exactly what we have often said a real live craft paper should be. Tall doings in New York City are reported in detail. Read every word. George Yager of L.U. 250, Salt Lake, scores a hit with some very pertinent comment anent work, wages and safety. As we expected, M. D. O'Brien, of Loew Theatres, defaulted on his assignment — but only until next month. After all, what can one expect from a projection supervisor? Nothing, just nothing. WE'VE had a lot of fun editing this exhibitor comment on projection matters. ' Our blue pencil has cut many a searing word relative to exhibitors; and now that Mr. Exhibitor has his say, he deals out nothing but kind words to the projectionist slaves. Just a case of turning the other cheek, we think. The more rabid LP. clientele likely will shout lustily: "Conspiracy!". To which we'll turn the other cheek and advise a careful reading of Charles ("Chick") Lewis' article in this issue. What a man he is! ivhat an exhibitor! NOW that the new aperture has been introduced all around, there is considerable chatter current regarding the relative merits of square and round corners for screens. Personally we like square corners; many of our friends prefer the roundies. Palpably a matter of personal taste, our liking for the square corner is based on the notion that there is something decisive, something all-inclusive about a square screen; while the round corner seems to invite the eyes to stray off the edges of the picture and wander about. We just know that some up-and-coming technician is going to try to explain this matter by handing out a big dose of psychology — but even after he has finished his argument, we still will vote for the square picture. BOOKS could be written on the oneman vs. two-men sound shift situation (although the sale probably wouldn't exceed 58 copies, C.O.D. ) . Still, we are forced to admit that after a trip to Columbus (which, you will recall, was to have settled this question) and after listening to several oracles discourse on this topic, we have to report that not a single sane argument has filtered through the smoke to our ears. Just to show how smart we really are. and to give aid and comfort to our thousands of palpitating readers, we shall present in these columns next month our idea on two-men shifts. It's all really very simple: there are four solid arguments, airtight, too, and we shall discuss each and every one in detail. On the right, please.
