MONTHLY CHAT INTERNATIONAL PROJECTIONIST has begun to spread itself. Reaching out to the West Coast it has gathered to its bosom "Loudspeaker," West Coast organ of the American Projection Society. The arrangement naturally embraces a transfer of all assets of "Loudspeaker"— subscriptions, advertising, and prestige — to LP. Paid subscriptions are, of course, of vital importance to any worthwhile publication; yet we like to think that of the aforementioned assets the most valuable is prestige. LP. is not insensible to the great responsibility it has assumed through consummation of this arrangement. Under the extremely able direction of Wallace G. Crowley, and by virtue of the support accorded it by Western A.P.S. men, "Loudspeaker" enjoyed an enviable reputation in the field and served its readers splendidly. We who work for LP. are conscious of the new responsibilities for giving service and of our now greatly increased audience. We shall try hard to discharge our obligation to former "Loudspeaker" readers by doing, if possible, just as fine a piece of work as have Mr. Crowley and his associates. Had we acquired a string of sectional motion picture periodicals throughout the country (Heaven help us!), we should not have been more pleased than we are concerning the "Loudspeaker" arrangement; and we earnestly hope that our many new readers will bear similar friendly feelings for LP. This last should not be too much for which to hope, inasmuch as we shall continue to have the close cooperation of Mr. Crowley and his associates. OVERLY optimistic as we are, we have concluded that William F. Canavan's resignation as President of the International Alliance will serve one useful purpose: it will teach all units and the entire membership the meaning of self-reliance, the need for which was not so pronounced during Mr. Canavan's tenure of office. (PROJECTION has much to look forward to during the coming year, if only because it has not received its rightful due during 1931. During the past year major emphasis was placed upon costs; production and reproduction were left to make their own way with whatever tools were available. It seems reasonable to assume that The equipment market will soon feel the impetus of purchases long deferred. *jM«tt!li^^a
