One morning the oldest Frog-Hopper brother thought that the sap pumped very hard. It may be that it did pump hard, and it may be that he was tired or lazy. Anyway, he began to grumble and find fault. "This is the worst stalk of golden-rod I ever saw in my life," he said. "It doesn't pay to try to pump any more sap, and I just won't try, so there!"

He was quite right in saying that it was the worst stalk he had ever seen, because he had never seen any other, but he was much mistaken in saying that it didn't pay to pump sap, and as for saying that "it didn't pay, so there!" we all know that when insects begin to talk in that way the best thing to do is to leave them quite alone until they are better-natured.

The other Frog-Hopper children couldn't leave him alone, because they hadn't changed their skins for the last time. They had to stay in their foam until that was done. After the big brother spoke in this way, they all began to wonder if the sap didn't pump hard. Before long the big sister wiggled impatiently and said, "My beak is dreadfully tired."

Then they all stopped eating and began to talk. They called their home stuffy, and said there wasn't room to turn around in it without hitting the foam. They didn't say why they should mind hitting the foam. It was soft and clean, and always opened up a way when they pushed against it.

"I tell you what!" said the big brother, "after I've changed my skin once more and gone out into the great world, you won't catch me hanging around this old golden-rod."

"Nor me!" "Nor me!" "Nor me!" said the other young Frog-Hoppers.

"I wonder what the world is like," said the little sister. "Is it just bigger foam and bigger golden-rod and more Frog-Hoppers?"

"Huh!" exclaimed her big brother. "What lots you know! If I didn't know any more than that about it, I'd keep still and not tell anybody." That made her feel badly, and she didn't speak again for a long time.

Then the little brother spoke. "I didn't know you had ever been out into the world," he said.

"No," said the big brother, "I suppose you didn't. There are lots of things you don't know." That made him feel badly, and he went off into the farthest corner of the foam and stuck his head in between a golden-rod leaf and the stalk. You see the big brother was very cross. Indeed, he was exceedingly cross.
