secret of the peach, the pineapple, the succulent vegetable! How she holds in the other the no less wonderful se cret of the means that shall carry her bounty to any table-anywhere-any time of the year. Today, all these ingredients lie dor mant together. Tomorrow, rising from the earth, they meet again, each to triumph in "the miracle on your table." But Nature's triumph means man's triumph, also. The tin can of com merce was not born in a day nor with out great industrial travail. The can-making industry in America parallels that of food-canning itself. In the beginning, each canner made his own cans, and a workman in those days could make by hand 150 per day. Today, production of more than Six Billion cans annually for the canned food output of America is significant of the development of the tin can in dustry, and of the canned food in dustry, as well, which makes all these millions upon millions of cans neces sary. The imagination is staggered by it. Expressed in terms of tables supplied, and of individuals served, it is almost beyond belief. The "tin" can is a steel can, coated with tin. It is a product of science, of scientific research by hundreds of specialists who have studied every step of evolution beginning with analysis of the steel itself. For example, over a period of years, picked men from the laboratories of four great organizations united in the common effort of developing the tin container. These were the labora tories of steel manufacturers, tin-plate manufacturers, can manufacturers, and the National Canners Association. Special "heats" of steel were experi mented with, foods packed in the cans produced from the steel, and the re sults recorded with scientific accuracy. The thickness of the tin coating be came a matter of scientific determina tion. Methods of sealing and imper viousness of joints are subjects of closest scientific scrutiny. As the tin can stands on your grocer's shelves or on the shelves of your own pantry, this highly specialized little object claims your respect. The tin can unquestionably is the safest, most practicable and scientific food container that human skill and inge nuity have been able to devise for the benefit of mankind. NATIONAL CANNERS ASSOCIATION WASHINGTON, D. C. A nation-wide organizationformed in 1907, consisting of prducers of all varieties of hermetically sealed cannedfoods whichhave been sterilizedby heat. It neither produces, buys, nor sells. Its pur pose is to assure,for the mutual benefit of the industry and the public, the best canned foods that scientific knowledge and human skill can produce.
