generous helping of butter. A big bowl of strawberries will not count half so much as the cream and sugar you put over them. So you may realize that when you eat olive oil, butter, cream, and sugar, you are in the same danger as the horse eating oats, or as my two cows in the pear orchard; and if some day a surgeon has to come and stick a knife into you, it may be for the same reason. The old-fashioned diet standards are as follows: Swedish laborers at hard work, over 4,700 calories; Russian workmen at moderate work, German soldiers in active service, Italian laborers at moderate work, between 3,500 and 3,700 calories; English weavers, nearly 3,500 calories; Austrian farm laborers, over 5,000 calories. Some twenty years ago the United States government made observations of over 15,000 persons, and established the following, known as the "Atwater standards": men at very hard muscular work, 5,500 calories; men at moderately active muscular work, 3,400 calories; men at light to moderate muscular work, 3,050 calories; men at sedentary, or women at moderately active work, 2,700 calories. In the last ten or fifteen years there has arisen a new school of dietetic experts, headed by Professors Chittenden and Fisher of Yale University. Professor Chittenden has published an elaborate book, "The Nutrition of Man," in which he tells of long-continued experiment upon a squad of soldiers and a group of athletes at Yale University, also upon average students and professors. He has proved conclusively that all these various groups have been able to maintain full body weight and full working efficiency upon less than half the quantity of protein food hitherto specified, and upon anywhere from one-half to two-thirds the calory value set forth in the former standards.
