On every hand we hear the call for power and more power. Every scientific genius in the world directs his attention to increasing power units in the struggle for world trade on which we are entering following a World War. Business calls for quicker transportation and the motor world answers with master motors; railroads are being or have been electrified; water power developments are being pushed in many parts of the country. The business world calls for more power and the aeroplanes answer with the delivery of mail and soon we are told it will enter the strictly commercial field. But what of man? What is being done to make him stand up under this terrific strain; this keener competition? What of the food that must keep him going? What of products that must be put before him with the middle man standing between? A nut bearing tree is the most powerful engine in the world if its fruits be properly used. If the people of the United States could have nut bearing trees for their "middlemen" in the fight to bring down the High Cost of Living it would come down quickly. Nuts are the most important of all tree crops because they are the richest natural food substance known. A nut is Nature's supreme effort to pack as much nourishment as she can into the smallest possible space for the nourishment of the future young plant. That some people are aware of these food values is evidenced in the nationwide tree balloting now being conducted by the American Forestry Association for the selection of a national tree. In this voting nut bearing trees are in the lead. Many nuts contain as much musclebuilding food as rich cheese, a third more than beef steak, twice as much fat as cheese, five times as much as eggs. Chestnuts contain 70 per cent of starch, nearly as much as the best wheat flour and four times as much as potatoes. Peanuts and hickory nuts are three times as nourishing as beefsteak. When you think of it that way it hardly seems to be the thing to casually munch triple extract of beefsteak from a street nut stand or after a hearty dinner. Say a fifty-pound bushel of black walnuts costs two dollars. It yields 12-1/2 pounds of meats whose fuel, or food value is 37,500 calories. The same number of calories in beefsteak at fifty cents a pound would cost more than fifteen dollars. A bushel of hickory nuts at three dollars yields as many calories as sixteen dollars' worth of round steak.
