MONTHLY CHAT TO those who piled up hundreds of letters in this office in praise of our stand relative to the current interpretation anent the overage-in-hours feature of the motion picture code, our thanks. Nothing contributes as much to the success of any battle as the knowledge that "the crowd" is with you. Our activities may not result in a modification of this vicious feature of the code, but at least it will be relatively simple to place the blame for the condition precisely where it belongs. OUR friends the lamp manufacturers, silent for lo, these many months, have burst into song in praise of the new A.C. carbon lamp, as is attested to in succeeding pages. Considerable interest has been whipped up in the projection field about these new A.C. lamps, and it should be added that there exists not a little difference of opinion as to the benefits to be derived from this development. Our time-tried and proven friend, Old Doc Time, will write the final answer to this question. BEFORE we publish another issue a group of New York City theatre owners — some 102 in number who have banded into an association — will have begun suit against ERPI on the score of excessive charges during the past five years and in opposition to compulsory servicing. If properly handled, this suit should go far toward clearing up this sound system servicing muddle. Meanwhile, from RCA-Victor Co., which does not impose compulsory servicing upon its customers, come reports which indicate that its Photophone system is playing a major role in breaking down the long-established numerical line-up of major sound companies. Congratulations, Mr. RCA-Victor, for an intelligent sales and servicing policy. THE distinguished Mr. F. H. Richardson hints that the code is not to his liking, and suggests that it was impioperly handled by the labor representatives present. Well, "Rich" might have been present himself and thus availed himself of a first-hand slant on the code run-around. NOW that the rounds have been made of practically all the available "brass hats" and stuffed shirts in America for appointment to the Code Authority, we should like to come forward and nominate for appointment none other than Dr. Alfred N. Goldsmith. The fact that Dr. Goldsmith is president of the S.M.P.E. and one of the outstanding engineers in this or any other country (we just couldn't resist this opportunity to smack the engineers) shouldn't be taken to mean that he doesn't know more about the various angles of the picture industry — production, acting, writing, distribution and exhibition AND LABOR — than the entire personnel of the present Authority. He does.
