Under the novel "Copper Matinee" plan, boys and girls are given free admission to matinee shows in exchange for a prescribed weight of copper of any type._ This plan, which supplements the drippings-saving program, has brought to light a considerable amount of metal which otherwise would not be made available for war use. In devoting performances to the collection of copper, the country's theatres are performing a patriotic duty by adding to the available supply of this important metal. The success of the program is important to the motion picture industry, as well as to the country as a whole.

Because of the oxidized appearance of the metal, scrap dealers, who judge the copper by its color, will not accept these gray-colored pellets and strips as usable metal.

If projector scrap is turned over to The spontaneous response to the copper conservation program in virtually every section of the country has resulted in the collection of many tons of copper drippings and peelings. This accumulation was made possible by the active cooperation of the large majority nected with projection. Reports received indicate that some motion picture supply houses have collected 9,000 to 10,000 pounds and more of copper drippings and peelings. This was accomplished by varying degrees of promotion on the part of these organizations. Advertising in the trade publications, direct mail and window displays showing the amount of scrap turned in supplemented the work of the field organizations in some cases. The theatres, in turn, have done their part by turning in their scrap regularly. While the copper-saving record established to date is excellent, it can be improved if every supply house and theatre in the country will give maximum cooperation. Some theatres, we understand, are turning in unpeeled stubs of used projector carbons. As a result, motion picture supply houses are having difficulty in disposing of the copper scap. To facilitate disposition, may we urge you, therefore, to avoid mixing stubs with drippings and peelings. ings Does Not Affect Usable Metal the supply houses for handling, the metal will find its way back into the Nation's stockpile without delay.
