It being the custom in their family, the newcomers built quite low in the tree. Such a happy time as they had. Every bit of grass root which either of them dragged loose and brought to the tree, was the prettiest and stoutest and best they had ever seen. And when it got to the Horsehairs for lining, they visited all the barns for a block around, hunting for them. Once, when Mrs. Hairbird wished for a white hair for one particular place, Mr. Hairbird even watched for a white Horse, and pulled it out of his tail.

You can imagine how surprised the Horse was when he felt that little tweak at his tail, and, looking around, saw a small brown bird pulling at one of his longest hairs. “I am sorry to annoy you,” said this bird, “but Mrs. Hairbird needed a white hair.”

“That is all right,” said the Horse, to whom one hair was a very small matter, and who dearly loved a joke. “Please tell Mrs. Hairbird that my tail is hers if she wishes it.”

“Your tail is hers!” exclaimed Mr. Hairbird, who ought to have seen the joke, since he was not an English Sparrow. “Oh, no, surely not! Surely your tail is not her tail. They are quite different, you know!” Then he understood and hurried away, but not in time to help hearing the Horse laugh.

When the white hair was woven in, the nest was done, and Mrs. Hairbird laid in it four greenish blue eggs with dark brown specks. In the nest above were six greenish white ones with brown and light purple spots. In the nest above that were five dingy streaked and speckled ones. Mrs. Hairbird said that hers were by far the prettiest. “It is not because I laid them,” she said to her husband. “It is not for that reason that I think so, but they really are.”

Mr. and Mrs. Hairbird were the only ones who paid for the chance to build in the tree. They picked insects off the branches, insects that would have robbed the tree of some of its strength.

The Blackbirds would not bother with such small bits of food. The English Sparrows should have paid in the same way, but they would not.

Their great-great-great- —a great many times great- —grandparents were brought over to this country just to eat the insects which were hurting the trees and shrubs, but when they got here they would not do it. “No, indeed,” said they; “we are here now, and we will eat what we choose.” Their great-great-great- —a great many times great- —grandchildren were just like them.

Silvertip often came to sit under this tree. He called it a family tree, because it had so many little families in its branches. He could not climb it. The fine branches and twigs were so close together that he could not get up the trunk, and they were not strong enough for him to step from one to another of them.

As might perhaps have been expected, there was some gossipping among neighbors in this tree. The Blackbirds usually climbed to their nest by beginning at the bottom of the trunk and going around and around it to the top. This took them so close to the other nests that they could not help looking in. At any rate, they didn’t help it.
