But his slow notes were queerer still. Though he tried to make them rollicking and merry, he succeeded only in giving a number of doleful whines.

[p. 67]"That won't do!" he exclaimed. "I declare, I haven't caught the trick yet." And to his great distress he heard Mrs. Bobolink weeping.

Now, Mr. Catbird had only wanted to have a jolly time with the Bobolink family. He had intended to sing one of Bobby's songs a few times, until they were puzzled; and then he had expected to dash out of the bush where he was hiding and have a good laugh with Mr. and Mrs. Bobolink. But somehow his plans were turning out all wrong.

"What shall I do?" Mr. Catbird groaned. "Here I've gone and frightened Bobby Bobolink's wife! Something's the matter with my voice. And I don't dare to try another song for fear she'll fall into a faint."

Then an idea flashed into his head. "If she knows who's hiding in this bush Mrs.[p. 68] Bobolink won't be frightened!" And thereupon he mewed almost exactly like Farmer Green's cat. But the sound was just different enough for Bobby Bobolink to know at once who made it.

"It's all right!" he told his wife merrily. "Don't worry! Mr. Catbird is hiding somewhere. He has been teasing us!"

Then Mr. Catbird came out of the bush and apologized like the gentleman he was.

"I didn't mean to frighten Mrs. Bobolink," he explained. "I was only trying to mock you. But there's something wrong with my voice. I think I'll have to go and see Aunt Polly Woodchuck, the herb doctor."

Bobby Bobolink only laughed harder than ever.

"There's nothing the matter with you!" he cried. "There isn't anybody that can imitate my songs—unless it's one of the[p. 69] Bobolink family. I sing too fast for you—that's the trouble."
