I said that Nature was severe and methodical, and so she is, where she needs to be, so severe that you are glad, perhaps, that you are not a crow. But Nature, like every wise mother, is severe only where she needs to be. A crow’s wing feathers are vastly important to him. Let him then take care of them, for they are the best feathers made and are put in to stay a year. But a crow’s tail feathers are not so vastly important to him; he could get on, if, like the rabbit in the old song, he had no tail at all.
In most birds the tail is a kind of balance or steering-gear, and not of equal importance with the wings. Nature, consequently, seems to have attached less importance to the feathers of the tail. They are not so firmly set, nor are they of the same quality or kind; for, unlike the wing feathers, if a tail feather is lost through accident, it is made good, no matter when. How do you explain that? Do you think I believe that old story of the birds roosting with their tails out, so that, because of generations of lost tails, those feathers now grow expecting to be plucked by some enemy, and therefore have only a temporary hold?
The normal, natural way, of course, is to replace a lost feather with a new one as soon as possible. But, in order to give extra strength to the wing feathers, Nature has found it necessary to check their frequent change; and so complete is the check that the annual moult is required to replace a single one. The Japanese have discovered the secret of this check, and are able by it to keep certain feathers in the tails of their cocks growing until they reach the enormous length of ten to twelve feet.
My crow, it seems, lost his three feathers last summer just after his annual moult; the three broken shafts he carries still in his wing, and must continue to carry, as the stars must continue their courses, until those three feathers have rounded out their cycle to the annual moult. The universe of stars and feathers is a universe of law, of order, and of reason.
CHAPTER VI
A CHAPTER OF THINGS TO DO THIS SPRING
I do not know where to begin—there are so many interesting things to do this spring! But, while we ought to be interested in all of the out-of-doors, it is very necessary to select some one field, say, the birds or flowers, for special study. That would help us to decide what to do this spring.

If there is still room under your window, or on the clothes-pole in your yard, or in a neighboring tree, nail up another bird-house. (Get “Methods of Attracting Birds” by Gilbert H. Trafton.) If the bird-house is on a pole or post, invert a large tin pan over the end of the post and nail the house fast upon it. This will keep cats and squirrels from disturbing the birds. If the bird-house is in a tree, saw off a limb, if you can without hurting the tree, and do the same there. Cats are our birds’ worst enemies.
