The Frozen Pond by Grant Allen — Read

THE pond on the moor is frozen over. What an epoch in the history of all its inhabitants! For they are not mostly long-lived creatures, these pond-dwellers; a summer forms an appreciable part of their short existence. Theirs is but a precarious life at the best of times; they have always to steer close between the Scylla of drought and the Charybdis of freezing. Half their days are spent in enforced seclusion. In the summer the pond, which is their universe, is apt to dry up and fail them; in winter it stands its even chance of freezing solid and entombing them. To meet these two extreme contingencies, all the world of the pond has had to accommodate itself to the possible chances of its fickle environment. The newts, for example, come here to breed every spring. They must needs do so, indeed, because their young have gills like a salmon or a herring, and can only breathe in their earlier stages the diffuse oxygen held in suspension in water.

Newts, in fact, start in life as fish, but develop, half-way through, into lizard-like animals with lungs and legs, because of the annual drying up of their native waters. All higher life, indeed, was originally aquatic; it is only just because ponds dry up in summer that the ancestors of beasts and birds and reptiles ever ventured on dry land, at first for a brief excursion, and afterwards for a permanence. We are all in the last resort the descendants of amphibians. There are two kinds of newt in this pond, each with its own peculiar plan for meeting the difficulty of winter quarters.
