These two tree-toads could not have been induced to trade houses, the hickory for the apple, because a house to a toad means home, and a home is never in the market. There are many more houses in the land than homes. Most of us are only real-estate dealers. Many of us have never had a home; and none of us has ever had, perhaps, more than one, or could have--that home of our childhood. This toad seemed to feel it all. Here in the hickory for four years (more nearly seven, I am sure) he lived, single and alone. He would go down to the meadow when the toads gathered there to lay their eggs; but back he would come, without mate or companion, to his tree. Stronger than love of kind, than love of mate, constant and dominant in his slow cold heart was his instinct for home. If I go down to the orchard and bring up from an apple tree some other toad to dwell in the hole of the hickory, I shall fail. He might remain for the day, but not throughout the night, for with the gathering twilight there steals upon him an irresistible longing; and guided by it, as bee and pigeon and dog and man are guided, he makes his sure way back to his orchard home. Would my toad of the Baldwin tree go back beyond the orchard, over the road, over the wide meadow, over to the old tree, half a mile away, if I brought him from there? We shall see. During the coming summer I shall mark him in some manner, and bringing him here to the hickory, I shall then watch the old apple tree yonder to see if he returns. It will be a hard, perilous journey. But his longing will not let him rest; and, guided by his mysterious sense of direction,--for that _one_ place,--he will arrive, I am sure, or he will die on the way. Suppose he never gets back? Only one toad less? A great deal more than that. There in the old Baldwin he has made his home for I don’t know how long, hunting over its world of branches in the summer, sleeping down in its deep holes during the winter--down under the chips and punk and castings, beneath the nest of the owls, it may be; for my toad in the hickory always buried himself so, down in the débris at the bottom of the hole, where, in a kind of cold storage, he preserved himself until thawed out by the spring. I never pass the old apple in the summer but that I stop to pay my respects to the toad; nor in the winter that I do not pause and think of him asleep in there. He is no longer mere toad. He has passed into the Guardian Spirit of the tree, warring in the green leaf against worm and grub and slug, and in the dry leaf hiding himself, a heart of life, within the thin ribs, as if to save the old shell of a tree to another summer. Often in the dusk, especially the summer dusk, I have gone over to sit at his feet and learn some of the things that my school-teachers and college professors did not teach me.
