billy bull frog had a deep bass voice, and every night he would sit on a big flat rock amid tall sedge grass and sing. there was a little green lady frog that sang a beautiful soprano, but, you see, his voice was so loud and strong and deep that hardly any one could hear her when she sang. she could hardly ever hear herself, for the louder she sang the more noise billy would make, till finally the little green lady frog wouldn't sing at all.
but this did not make billy feel badly, because he loved to hear his own voice so much. the little green lady frog would sit very still on her lily pad, and would not even look at billy when he sang. but, oh, dear me! he was so conceited about his own voice that he thought the little green lady frog was jealous of him.
she wasn't at all, and billy was wrong, and was acting very, very foolishly. the real truth of the matter was that the little green lady frog had heard a tree toad singing in a tree quite close to the lake, and she thought his voice very beautiful, because it was a high tenor, and it sounded much better when she sang with him than it did when she sang with billy bull frog.
at first she hardly dared sing with tommy tree toad, because she was afraid of billy bull frog, and then, too, she didn't know tommy tree toad very well.
but after a while she became bolder and one night, when the moon was shining brightly in the sky and throwing a silver path from the water right up to tommy tree toad's tree, she climbed up the bank and stood on the silver path of the moon and listened while tommy sang his most beautiful song.
and the longer she waited the more she wanted to go close up to the big tree and sing with tommy. he kept singing in his beautiful tenor voice, "kum-kum, kum-kum!" and at last she hopped along the silver way up to the big tree. and then they sang a lovely duet together and all the frogs in the lake held their breath because it was so sweet.
