On the coldest days of winter a white-haired man, nearly seventy years of age, may be seen walking New York streets, without a hat, clad only in light “Palm Beach” trousers, and a silk negligée shirt, open at the throat. “He is crazy,” you say. “Perhaps,” I answer, “but at any rate he is healthy--and immune from cold.” Heatless days mean nothing to him. On a raw, drizzling day in November last a slender man was playing golf in a light woolen suit. A companion player, weighing over 200 pounds, full blooded and hearty in appearance, and bundled up in two heavy sweaters, asked the lightly clad player if he was not afraid of catching a fatal cold. “No,” he answered, “_you_ are the one that gives me concern. If I had your clothing on I would be a sick man. _I am not healthy enough_ to wear all those things.” * * * * * Which means that we would be better off in health if we could accustom ourselves to less heat; if we could live as the people of some other nations do--comfortable and content with heat enough to take the chill off the air, and not demanding that we shall be “kept going” by means of artificial heat outside of our own natural heat-giving apparatus. We make caloric cripples of ourselves by giving crutches to nature in the form of roaring furnaces and hissing steam pipes. Fresh cold air is better for us than hot air--in winter as well as in summer. Would it not be worth while to form a national Fresh Air Fraternity, based on the principle of foregoing artificial heat and developing the original body caloric? We would then leave artificial heat largely to infants, weaklings and invalids; we would abolish several diseases altogether, improve the mortality rate, and be healthy, happy and vigorous. Incidentally, too, we would have more coal for cooking and other really necessary purposes. [Illustration: W. D. Moffat EDITOR] IN THE HIGH SCHOOL The Mentor is a part of our High School. Each day 192 pupils and 11 teachers have opportunity to partake of its splendid contents. Think of a big family of 200 enjoying it daily. I say daily because I have all the back numbers, and each day a new Mentor with all its gravures is displayed on a specially constructed rack in my recitation room. The important features to be found in it are enumerated on the blackboard, and after having pursued this method for a year I am anxious to tell you something about it. One sixth of the members of the graduating class at the end of the year chose Mentor subjects for their theses, and, from the supplementary reading list given, selected books, which were obtained by mail from the Carnegie Library at Pittsburgh, with a result that all the theses were most excellent. The Mentor is not filled with current material, which changes constantly and is good only for a short time. All you print will bear being assimilated and preserved. It is your small statements that make The Mentor big.
