“In a WHAT?” cried Peter. “In a hoofprint of Bossy the Cow,” repeated Sweetvoice, chuckling softly. “You know when the ground was wet and soft early this spring, Bossy left deep footprints wherever she went. One of these makes the nicest kind of a place for a nest. I think we have picked out the very best one on all the Green Meadows. Now run along, Peter Rabbit, and don't bother me any more. I've got too much to do to sit here talking. Perhaps I'll come over to the edge of the dear Old Briar-patch and sing to you a while just after jolly, round, red Mr. Sun goes to bed behind the Purple Hills. I just love to sing then.” “I'll be watching for you,” replied Peter. “You don't love to sing any better than I love to hear you. I think that is the best time of all the day in which to sing. I mean, I think it's the best time to hear singing,” for of course Peter himself does not sing at all. That night, sure enough, just as the Black Shadows came creeping out over the Green Meadows, Sweetvoice, perched on the top of a bramble-bush over Peter's head, sang over and over again the sweetest little song and kept on singing even after it was quite dark. Peter didn't know it, but it is this habit of singing in the evening which has given Sweetvoice his name of Vesper Sparrow. CHAPTER V. Peter Learns Something He Hadn't Guessed. Running over to the Old Orchard very early in the morning for a little gossip with Jenny Wren and his other friends there had become a regular thing with Peter Rabbit. He was learning a great many things, and some of them were most surprising. Now two of Peter's oldest and best friends in the Old Orchard were Winsome Bluebird and Welcome Robin. Every spring they arrived pretty nearly together, though Winsome Bluebird usually was a few days ahead of Welcome Robin. This year Winsome had arrived while the snow still lingered in patches. He was, as he always is, the herald of sweet Mistress Spring. And when Peter had heard for the first time Winsome's soft, sweet whistle, which seemed to come from nowhere in particular and from everywhere in general, he had kicked up his long hind legs from pure joy. Then, when a few days later he had heard Welcome Robin's joyous message of “Cheer-up! Cheer-up! Cheer-up! Cheer-up! Cheer!” from the tiptop of a tall tree, he had known that Mistress Spring really had arrived. Peter loves Winsome Bluebird and Welcome Robin, just as everybody else does, and he had known them so long and so well that he thought he knew all there was to know about them. He would have been very indignant had anybody told him he didn't. “Those cousins don't look much alike, do they?” remarked Jenny Wren, as she poked her head out of her house to gossip with Peter. “What cousins?” demanded Peter, staring very hard in the direction in which Jenny Wren was looking. “Those two sitting on the fence over there. Where are your eyes, Peter?” replied Jenny rather sharply.
