That night they perched in the maple-tree and slept with their heads under their wings. Long before the sun was in sight, when the first beams were just touching the tops of the forest trees, they awakened, bright-eyed and rested, preened their feathers, sang their morning song, "Cheerily, cheerily, cheer-up," and flew off to find food. After breakfast they began to work on the nest. Mrs. Robin stopped often to look and peck at the bark. "It will take a great deal of mud," said she, "to fill in that deep crotch until we reach a place wide enough for the nest." At another time she said: "My dear, I am afraid that the dry grass you are bringing is too light-colored. It shows very plainly against the maple bark. Can't you find some that is darker?" Mr. Robin hunted and hunted, but could find nothing which was darker. As he flew past the fence, he noticed that it was almost the color of the grass in his bill. After a while, soft gray clouds began to cover the sky. "I wonder," said Mrs. Robin, "if it will rain before we get this done. The mud is soft enough now to work well, and this place is so open that the rain might easily wash away all that we have done." It did rain, however, and very soon. The great drops came down so hard that one could only think of pebbles falling. Mr. and Mrs. Robin oiled their feathers as quickly as they could, taking the oil from their back pockets and putting it onto their feathers with their bills. This made the finest kind of waterproof and was not at all heavy to wear. When the rain was over they shook themselves and looked at their work. "I believe," said Mrs. Robin to her husband, "that you are right in saying that we might better give up this place and begin over again somewhere else." Now Mr. Robin could not remember having said that he thought anything of the sort, and he looked very sharply at his wife, and cocked his black head on one side until all the black and white streaks on his throat showed. She did not seem to know that he was watching her as she hopped around the partly built nest, poking it here and pushing it there, and trying her hardest to make it look right. He thought she would say something, but she didn't. Then he knew he must speak first. He flirted his tail and tipped his head and drew some of his brown wing-feathers through his bill. Then he held himself very straight and tall, and said, "Well, if you do agree with me, I think you might much better stop working here and begin in another place." "It seems almost too bad," said she. "Of course there are other places, but----" By this time Mr. Robin knew exactly what to do. "Plenty of them," said he. "Now don't fuss any longer with this. That place on the rail fence is an excellent one. I wonder that no other birds have taken it." As he spoke he flew ahead to the very spot which Mrs. Robin had first chosen.
