“That noise is made by a little green bug, called a katydid,” Mr. Brown explained.  “It looks something like a grasshopper.”

“But they don’t all say ‘Katy did,’” objected Tom.

“No, some of them seem to say ‘Katy didn’t,’” agreed Mr. Brown.  “Of course they don’t really say those words.  It only sounds as if they did.  Now go to sleep.  In the morning I’ll show you a katydid.”

Tom was not frightened any longer.  He turned over and was soon sound asleep.  Mr. Brown and Bunker also closed their eyes and the tent in Camp Rest-a-While was quiet once more.  Bunny and Sue had not awakened.

Early the next morning, before breakfast, Tom was seen walking about among the trees of the camp.  He seemed to be looking for something.

“What are you looking for?” asked Bunny.

“For Katy,” Tom answered.

“There isn’t any Katy with us,” said Sue.  “We have a cook, but her name is Mary, and she isn’t here with us, anyhow.  She’s at home.”

“No, I’m looking for a Katy bug,” explained Tom, and then he told about the noises he had heard in the night.

“I’ll help you look,” said Bunny.

“So will I,” added Sue.  “I’d like to see a Katy bug.”

But, though the children and Tom looked all over, they could not find a katydid until Mr. Brown helped them.  Then on a tree he found one of the queer, light-green grasshopper-like bugs and showed it to the children.

“Why doesn’t it cry now?” Sue wanted to know.  “Make it cry, Daddy, so I can hear it!”

“Oh, I can’t do that,” Mr. Brown said with a laugh.  “The katydid cries, or sings, mostly at night.  I guess they don’t want anyone to see them.  Besides, I don’t just know how they make the noises, whether they rub their rough legs together, or make a sound somewhere inside them.  So I guess we’ll have to let them do as they please.”

Tom and the children stood for some little time, watching the pretty, green bug, and then came the sound of a bell.

“There!” cried Mr. Brown, with a laugh.  “I guess you all know who made that noise, and what it means.”

“It means breakfast!” cried Bunny.

“And mother rang the bell!” added Sue.

“That’s right,” said Bunker Blue, coming along just then.  “And your mother doesn’t want you to be late, either, for she’s baking cakes, and you know how you like them!”

“Oh, cakes!” cried Bunny, clapping his hands.  “I just love them!”

Soon the little party, including the new boy, Tom Vine, were seated around the table under the dining tent, eating pancakes that Mrs. Brown cooked over the oil stove.

Bunny and Sue said nothing for several minutes.  They were too busy eating.  Then Bunny, looking at Tom, asked: 

“Can you jump over an elephant?”

“Jump over elephants?  I guess not!” the new boy cried.  “I never saw an elephant, except in a picture.”
