This is his shift! This is the length to which he goes, because he has no wings, and because he cannot cut, cure, and mow away in the depths of the stony hillside, enough clover hay to last him over the winter. The beaver cans his fresh food in cold water; the chipmunk selects long-keeping things and buries them; the woodchuck makes of himself a silo, eats all his winter hay in the summer while it is green, turns it at once into a surplus of himself, then buries that self, feeds upon it, and sleeps—and lives! The north wind doth blow, And we shall have snow, but what good reason is there for our being daunted at the prospect? Robin and all the others are well prepared. Even the wingless frog, who is also lacking in fur and feathers and fat, even he has no care at the sound of the cold winds. Nature provides for him too, in her way, which is neither the way for the robin, the muskrat, nor the woodchuck. He survives, and all he has to do about it is to dig into the mud at the bottom of the ditch. This looks at first like the journey Woodchuck takes. But it is really a longer, stranger journey than Woodchuck’s, for it takes the frog far beyond the realms of mere sleep, on into the cold, black land where no one can tell the quick from the dead. The frost may or may not reach him here in the ooze. No matter. If the cold works down and freezes him into the mud, he never knows. But he will thaw out as good as new; he will sing again for joy and love as soon as his heart warms up enough to beat. I have seen frogs frozen into the middle of solid lumps of ice in the laboratory. Drop the lump on the floor, and the frog would break out like a fragment of the ice itself. And this has happened more than once to the same frog without causing him the least apparent suffering or inconvenience. He would come to, and croak, and look as wise as ever. The north wind _may_ blow, but the muskrats are building; and it is by no means a cheerless prospect, this wood-and-meadow world of mine in the gray November light. The frost will not fall to-night as falls the plague on men; the brightness of the summer is gone, yet this chill gloom is not the sombre shadow of a pall. Nothing is dying in the fields: the grass-blades are wilting, the old leaves are falling, but no square foot of greensward will the winter kill, nor a single tree perhaps in my woodlot. There will be no less of life next April because of this winter, unless, perchance, conditions altogether exceptional starve some of the winter birds. These suffer most; yet as the seasons go, life even for the winter birds is comfortable and abundant.
