The web of relation is shown in _habitat_, shown in hibernation. When hibernation was observed, it was found, that, whilst some animals become torpid in winter, others were torpid in summer: hibernation then was a false name. The _long sleep_ is not an effect of cold, but is regulated by the supply of food proper to the animal. It becomes torpid when the fruit or prey it lives on is not in season, and regains its activity when its food is ready. Eyes are found in light; ears in auricular air; feet on land; fins in water; wings in air; and each creature where it was meant to be, with a mutual fitness. Every zone has its own _Fauna_. There is adjustment between the animal and its food, its parasite, its enemy. Balances are kept. It is not allowed to diminish in numbers, nor to exceed. The like adjustments exist for man. His food is cooked when he arrives; his coal in the pit; the house ventilated; the mud of the deluge dried; his companions arrived at the same hour, and awaiting him with love, concert, laughter, and tears. These are coarse adjustments, but the invisible are not less. There are more belongings to every creature than his air and his food. His instincts must be met, and he has predisposing power that bends and fits what is near him to his use. He is not possible until the invisible things are right for him, as well as the visible. Of what changes, then, in sky and earth, and in finer skies and earths, does the appearance of some Dante or Columbus apprise us! How is this effected? Nature is no spendthrift, but takes the shortest way to her ends. As the general says to his soldiers, "If you want a fort, build a fort," so nature makes every creature do its own work and get its living--is it planet, animal, or tree. The planet makes itself. The animal cell makes itself; then, what it wants. Every creature--wren or dragon--shall make its own lair. As soon as there is life, there is self-direction, and absorbing and using of material. Life is freedom--life in the direct ratio of its amount. You may be sure, the new-born man is not inert. Life works both voluntarily and supernaturally in its neighborhood. Do you suppose he can be estimated by his weight in pounds, or that he is contained in his skin--this reaching, radiating, jaculating fellow? The smallest candle fills a mile with its rays, and the papillæ of a man run out to every star.
