Then the Eels talked among themselves about them. "I shall be glad," said one old Father Eel, "when these youngsters hide their breathing-gills and go to the top of the water."

"So shall I," exclaimed a Mother Eel. "They keep their tails wiggling so that it hurts my eyes to look at them. Why can't they lie still and be good?"

Now the Tadpoles looked at each other with their shining black eyes. "What are our breathing-gills?" they asked. "They must be these little things on the sides of our heads."

"They are!" cried the First Tadpole. "The Biggest Frog said so. But I don't see where we can hide them, because they won't come off. And how could we ever breathe water without them?"

"Hear the children talk," exclaimed the Green Brown Frog, who had come down to look the Tadpoles over and decide which were hers. "Why, you won't always want to breathe water. Before long you will have to breathe air by swallowing it, and then you cannot stay long under water. I must go now. I am quite out of breath. Good-bye!"

Then the Tadpoles looked again at each other. "She didn't tell us what to do with our breathing-gills," they said. One of the Tadpoles who had hatched last, swam up to the First Tadpole. "Your breathing-gills are not so large as mine," she said.

"They surely are!" he exclaimed, for he felt very big indeed, having been the first to hatch.

"Oh, but they are not!" cried all his friends. "They don't stick out as they used to." And that was true, for his breathing-gills were sinking into his head, and they found that this was happening to all the older Tadpoles.
