"Well, whatever you do," said a Vireo, "don't hatch the big egg out with your own. I did once, and such a time as I had! The young Cowbird pushed two of my little Vireos out onto the ground, and ate so much that I was quite worn out by the work of hunting for him." "My dear," said Mr. Goldfinch, "I have an excellent plan. We will put another floor in our nest, right over this egg, and then by adding a bit all around the sides we can have plenty of room for our own children. It will be much less work than beginning all over again, and then the Cowbird's egg will be too cool to hatch." Everybody called this a most clever plan, and Mr. Goldfinch was very proud to have thought of it. They went to work once more, and it was not so very long before the new floor was done and the new walls raised. Then, oh, wonder of wonders! there were soon four tiny, pearly eggs of their own lying on the thistle-down lining of the nest. Mrs. Goldfinch had to stay very closely at home now, but her husband went off with his friends a great deal. He bathed and sang and preened his feathers and talked about his queer nest and his bright little wife, after the manner of Goldfinches everywhere. His friends laughed at him for helping so much about the nest, for, you know, Goldfinches do not often help their wives about home. He cocked his handsome head on one side and answered: "My wife seemed to need me then. She is not so very strong. And I do not know what she would ever have done about the strange egg, if I had not been there to advise her." When he got back to his home that night, Mrs. Goldfinch said: "I have been wondering why we did not roll the Cowbird's egg out on the ground, instead of going to all that trouble of building around it." And Mr. Goldfinch declared that he believed she was the only bird who had ever thought of such a thing. "It could have been done just as well as not," he said. "I must tell that to the other birds in the morning. How lucky I am to have such a bright wife! It would be dreadful if such a clever fellow as I had a dull mate!" [Illustration] MRS. MOURNING DOVE'S HOUSEKEEPING Strange as it may seem, there had never been any Mourning Doves in the forest until this year, and when a pair came there to live, the people were much excited. They talked about the Doves' song, so sweet and sad, and about their soft coats of brown and gray, and they wondered very much what kind of home they would build. Would it be a swinging pocket of hairs, strings, and down, like that of the Orioles? Would it be stout and heavy like the nests of the Robins? Or would it be a ball of leaves and grasses on the ground, with a tiny doorway in one side, like that of the Ovenbird? You can see that the forest people were really very much interested in the Mourning Doves, and so, perhaps, it is not strange that, when the new couple built their nest in the lower branches of a spruce tree, everybody watched it and talked about it.
