Peter was so intent watching these two friends of his that he took no heed to his footsteps. Suddenly there was a whirr from almost under his very nose and he stopped short, so startled that he almost squealed right out. In a second he recognized Mrs. Meadow Lark. He watched her fly over to where Carol was singing. Her stout little wings moved swiftly for a moment or two, then she sailed on without moving them at all. Then they fluttered rapidly again until she was flying fast enough to once more sail on them outstretched. The white outer feathers of her tail showed clearly and reminded Peter of the tail of Sweetvoice the Vesper Sparrow, only of course it was ever so much bigger. Peter sat still until Mrs. Meadow Lark had alighted on the fence near Carol. Then he prepared to hurry on, for he was anxious for a bit of gossip with these good friends of his. But just before he did this he just happened to glance down and there, almost at his very feet, he caught sight of something that made him squeal right out. It was a nest with four of the prettiest eggs Peter ever had seen. They were white with brown spots all over them. Had it not been for the eggs he never would have seen that nest, never in the world. It was made of dry, brown grass and was cunningly hidden is a little clump of dead grass which fell over it so as to almost completely hide it. But the thing that surprised Peter most was the clever way in which the approach to it was hidden. It was by means of a regular little tunnel of grass. “Oh!” cried Peter, and his eyes sparkled with pleasure. “This must be the nest of Mrs. Meadow Lark. No wonder I have never been able to find it, when I have looked for it. It is just luck and nothing else that I have found it this time. I think it is perfectly wonderful that Mrs. Meadow Lark can hide her home in such a way. I do hope Jimmy Skunk isn't anywhere around.” Peter sat up straight and anxiously looked this way and that way. Jimmy Skunk was nowhere to be seen and Peter gave a little sigh of relief. Very carefully he walked around that nest and its little tunnel, then hurried over toward the fence as fast as he could go. “It's perfectly beautiful, Carol!” he cried, just as soon as he was near enough. “And I won't tell a single soul!” “I hope not. I certainly hope not,” cried Mrs. Meadow Lark in an anxious tone. “I never would have another single easy minute if I thought you would tell a living soul about my nest. Promise that you won't, Peter. Cross your heart and promise that you won't.” Peter promptly crossed his heart and promised that he wouldn't tell a single soul. Mrs. Meadow Lark seemed to feel better. Right away she flew back and Peter turned to watch her. He saw her disappear in the grass, but it wasn't where he had found the nest. Peter waited a few minutes, thinking that he would see her rise into the air again and fly over to the nest. But he waited in vain. Then with a puzzled look on his face, he turned to look up at Carol.
