Warm-Coated Animals Avoid "Fresh Air." On this subject there is a strange divergence of reasoning power between the wild animals of cold countries and the sleeping-porch advocates of today. Even the most warm-coated of the fur-bearing animals, such as the bears, foxes, beavers, martens and mink, and also the burrowing rodents, take great pains to den up in winter just as far from the "fresh air" of the cold outdoors as they can attain by deep denning or burrowing. The prairie-dog not only ensconces himself in a cul-de-sac at the end of a hole fourteen feet deep and long, but as winter sets in he also tightly plugs up the mouth of his den with moist earth. When sealed up in his winter den the black bear of the north draws his supply of fresh air through a hole about one inch in diameter, or less. But the human devotees of fresh air reason in the opposite direction. It is now the regular thing for mothers to open wide to the freezing air of out-doors either one or all the windows of the rooms in which their children sleep, giving to each child enough fresh air to supply ten full-grown elephants, or twenty head of horses. And the final word is the "sleeping-porch!" It matters not how deadly damp is the air along with its 33 degrees of cold, or the velocity of the wind, the fresh air must be delivered. The example of the fat and heavily furred wild beast is ignored; and I just wonder how many people in the United States, old and young, have been killed, or permanently injured, by fresh air, during the last fifteen years. And furthermore. Excepting the hoofed species, it is the universal rule of the wild animals of the cold-winter zones of the earth that the mother shall keep her helpless young close beside her in the home nest and keep them warm partly by the warmth of her own body. The wild fur-clad mother does not maroon her helpless offspring in an isolated cot in a room apart, upon a thin mattress and in an atmosphere so cold that it is utterly impossible for the poor little body and limbs to warm it and keep it warm. Yet many human mothers do just that, and some take good care to provide a warmer atmosphere for themselves than they joyously force upon their helpless infants. No dangerous fads should be forced upon defenseless children or animals. A proper amount of fresh air is very desirable, but the intake of a child is much less than that of an elephant. Besides, if Nature had intended that men should sleep outdoors in winter, with the moose and caribou, we would have been furnished with ruminant pelage and fat. VII KEEN BIRDS AND DULL MEN If all men could know how greatly the human species varies from highest to lowest, and how the minds and emotions of the lowest men parallel and dove-tail with those of the highest quadrupeds and birds, we might be less obsessed with our own human ego, and more appreciative of the intelligence of animals.
