I should say that there might easily be five hundred young ones in the family, though I never have counted them. But you might. If you want to try it, take your small scoop-net of coarse cheesecloth, or mosquito-netting, and go down to the pond this spring. Close along the margin you will see holes in the shallow water running up under the overhanging grass and roots. The holes were made probably by the muskrats. It is in here that the old catfish is guarding the brood. As soon as you learn to know the holes, you can cover the entrance with your net, and then by jumping or stamping hard on the ground above the hole, you will drive out the old fish with a flop, the family following in a fine, black cloud. The old fish will swim away, then come slowly back to the scattered swarm, to the little black things that look like small tadpoles, who soon cluster about the parent once more and wiggle away into the deep, dark water of the pond--the strangest family group that I know in all the spring world. CHAPTER III AN OLD APPLE TREE Beyond the meadow, perhaps half a mile from my window, stands an old apple tree, the last of an ancient line that once marked the boundary between the “upper” and the “lower” pastures. It is a bent, broken, hoary old tree, grizzled with suckers from feet to crown. No one has pruned it for half a century; no one ever gathers its gnarly apples--no one but the cattle who love to lie in its shadow and munch its fruit. The cows know the tree. One of their winding paths runs under its low-hung branches; and as I frequently travel the cow-paths, I also find my way thither. Yet I do not go for apples, nor just because the cow-path takes me. That old apple tree is hollow, hollow all over, trunk and branches, as hollow as a lodging-house; and I have never known it when it was not “putting up” some wayfaring visitor or some permanent lodger. So I go over, whenever I have a chance, to call upon my friends or pay my respects to the distinguished guests. This old tree is on the neighboring farm. It does not belong to me, and I am glad; for if it did, then I should have to trim it, and scrape it, and plaster up its holes, and put a burlap petticoat on it, all because of the gruesome gypsy moths that infest my trees. Oh, yes, that would make it bear better apples, but what then would become of its birds and beasts? Everybody ought to have _one_ apple tree that bears birds and beasts--and Baldwin apples, too, of course, if the three sorts of fruit can be made to grow on the same tree. But only the birds and beasts grow well on the untrimmed, unscraped, unplastered, unpetticoated old tree yonder between the pastures. His heart is wide open to every small traveler passing by.
