Shoes.-- The feet are the part of the body to come in contact with the greatest degree of cold, whether on the floor of the house or the pavement of the street. Hence it is a matter of prime importance to the entire body that the feet should be properly clad. The thick-soled, flat-heeled shoes which became popular with bicycling and golf are most hygienic, and it is highly desirable that this style of shoe should be adhered to for outdoor exercise. Underwear.-- In our cold and changeable climate the most suitable undergarment is the "combination" woolen undersuit, which reaches from neck to ankles and has long sleeves. Much greater warmth is afforded when the undersuit is moderately tight fitting. Such a suit should be worn the entire year, the grade of weight being adapted to the season. Nutrition.-- The nutrition of the body is dependent on the food supply, digestion and excretion. The growing girl should eat more than the adult woman, because of her more active life and of the fact that the food which she takes must not only replace the worn-out material of the body, but also provide new material needed for growth. Insufficient food and food of defective quality and composition work proportionately for more harm during the growing age. The full adult weight is not attained before the twenty-fifth year. When the final growth of the body and development of the vital organs is completed, the function of food is simply to replace waste with new material and to furnish material for the development of force. Diet.-- The diet should be a mixed one, consisting of the various kinds of fresh meats, fish, milk, eggs, poultry, vegetables, fruit, and fat in the shape of cream, butter, and the fat of beef and mutton. Animal food improves the condition of the muscles, which are made firmer than they would be through a vegetable diet. Meat in general has a more stimulating effect upon the system and is more strengthening than vegetable food, and it gives rise to a sensation of energy and activity. The common estimate is that meat should occupy one-fourth and vegetable food three-fourths of a mixed diet. Common salt in moderate quantity is essential, but all highly spiced or seasoned foods should be avoided, also pickles and vinegar. All "sweets" are harmful, because they destroy the appetite for other things and upset the digestion. Tea and coffee should be tabooed, as well as all alcoholic beverages. Good digestion depends for the most part on serving the meals at the same hour every day, eating leisurely, and masticating the food well. There is a great tendency on the part of the school girl to sleep late in the morning, then "bolt" her breakfast in order to get to school in time. Nothing could be more pernicious to the digestion, unless it is the eternal nibbling of candy.
