“So you guess it is there!” mimicked Jenny Wren. “Well, your guess is quite wrong, Peter; quite wrong. As a matter of fact, it is in one of those old fence posts. But just which one I am not going to tell you. I will leave that for you to find out. Mrs. Bluebird certainly shows good sense. She knows a good house when she sees it. The hole in that post is one of the best holes anywhere around here. If I had arrived here early enough I would have taken it myself. But Mrs. Bluebird already had her nest built in it and four eggs there, so there was nothing for me to do but come here. Just between you and me, Peter, I think the Bluebirds show more sense in nest building than do their cousins the Robins. There is nothing like a house with stout walls and a doorway just big enough to get in and out of comfortably.”

Peter nodded quite as if he understood all about the advantages of a house with walls. “That reminds me,” said he. “The other day I saw Welcome Robin getting mud and carrying it away. Pretty soon he was joined by Mrs. Robin, and she did the same thing. They kept it up till I got tired of watching them. What were they doing with that mud?”

“Building their nest, of course, stupid,” retorted Jenny. “Welcome Robin, with that black head, beautiful russet breast, black and white throat and yellow bill, not to mention the proud way in which he carries himself, certainly is a handsome fellow, and Mrs. Robin is only a little less handsome. How they can be content to build the kind of a home they do is more than I can understand. People think that Mr. Wren and I use a lot of trash in our nest. Perhaps we do, but I can tell you one thing, and that is it is clean trash. It is just sticks and clean straws, and before I lay my eggs I see to it that my nest is lined with feathers. More than this, there isn't any cleaner housekeeper than I am, if I do say it.

“Welcome Robin is a fine looker and a fine singer, and everybody loves him. But when it comes to housekeeping, he and Mrs. Robin are just plain dirty. They make the foundation of their nest of mud,—plain, common, ordinary mud. They cover this with dead grass, and sometimes there is mighty little of this over the inside walls of mud. I know because I've seen the inside of their nest often. Anybody with any eyes at all can find their nest. More than once I've known them to have their nest washed away in a heavy rain, or have it blown down in a high wind. Nothing like that ever happens to Winsome Bluebird or to me.”

Jenny disappeared inside her house, and Peter waited for her to come out again. Welcome Robin flew down on the ground, ran a few steps, and then stood still with his head on one side as if listening. Then he reached down and tugged at something, and presently out of the ground came a long, wriggling angleworm. Welcome gulped it down and ran on a few steps, then once more paused to listen. This time he turned and ran three or four steps to the right, where he pulled another worm out of the ground.

“He acts as if he heard those worms in the ground,” said Peter, speaking aloud without thinking.

“He does,” said Jenny Wren, poking her head out of her doorway just as Peter spoke. “How do you suppose he would find them when they are in the ground if he didn't hear them?”

“Can you hear them?” asked Peter.

“I've never tried, and I don't intend to waste my time trying,” retorted Jenny. “Welcome Robin may enjoy eating them, but for my part I want something smaller and daintier, young grasshoppers, tender young beetles, small caterpillars, bugs and spiders.”

Peter had to turn his head aside to hide the wry face he just had to make at the mention of such things as food. “Is that all Welcome Robin eats?” he asked innocently.
