One well-known song was missing from the tall elm by the brook-side; and Flip, in spite of his excitement in singing, and his hopes that his courtship might be successful with a certain little brown member of a last year’s brood, could not help thinking now and then, with a heavy heart, of Pipi the best of singers, and of all the happiness they might have had but for that unlucky lighthouse. Twinkle too would sometimes remind him of his sorrow in [Illustration: Pipi looked up and saw Flip; in an instant they were together.--P. 205.] his blunt and selfish way, and Flip felt his company still so unpleasant that he moved to a tree further up the brook. One day, not long after the arrival of the hens, when Flip had made sure of his little spouse, and they were flying after one another from tree to tree round the field, then into another field and another, in loving chase, Flip caught a low song that made him stop instantly and perch. It sounded again from a low willow, and then Flip could see the singer moving about inside the tree, where the leaves were just beginning to appear. In another moment a willow-warbler fluttered out; its flight was feeble, and as it perched again, Flip could see that it held on with some difficulty to the twig, for its right leg was injured. But it was Pipi! Yes, it was Pipi beyond all doubt; and Flip, glued to his bough by amazement, gave out such a strain of song as he had never in his whole life before been able to produce. Pipi looked up and saw Flip; in an instant they were together, and in such a state of tremor and delight, that poor Mrs. Flip was left quite out in the cold, and became for the first time in her life jealous of a cock bird. “Never mind me,” said Pipi at last; “look at me, Mrs. Flip, a poor wreck, with a bruised bill, and a game leg, and only half a song: who could be jealous of me? Leave off fluttering round poor Flip, and let me tell him my story, and then you shall have him all to yourself.” So Mrs. Flip perched quietly on a bough hard by, for she was a sensible bird, or she would not have married Flip; and she had so often heard him talk of Pipi that she felt he must want sadly to hear the story.
