at's an owl?" Tom wanted to know.

"Oh, it's a bird with big eyes, and it can only see at night. It comes
out to get mice and bugs. Owls won't hurt you. Go on to sleep."

Tom did not go to sleep at once. But he was no longer afraid of the owl.

Tom was just going to sleep once more, when he heard another funny
noise. This time he was sure some one said:

"Katy did! Katy did! Katy did!"

Tom sat up in his cot. He reached over to punch Bunker, to ask him what
this was, when all at once, another voice cried:

"Katy didn't! Katy didn't! Katy didn't!"

"Listen to that, now, would you!" exclaimed Tom. "Bunker! Bunker Blue!
Wake up! There's two people outside, and one says Katy did it, and the
other says she didn't--who's right?"

CHAPTER X

OUT IN THE BOAT

Bunker Blue turned sleepily over on his cot.

"What--what's that?" he asked of Tom.

"Listen," Tom answered. "Don't you hear that, Bunker? First someone is
hollering about Katy's doing something, and then somebody else yells
that she didn't do it. Say, I don't like it here."

Bunker Blue laughed aloud.

"What's the matter out there?" asked Daddy Brown.

"Oh, it's only Tom," said the red-haired boy. "He doesn't like the song

"Song! Is that a song?" asked Tom.

"Some people call it that," said Mr. Brown, for he knew that a city boy
might be just as frightened of sounds in the country as a country boy
might of sounds in the city.

"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 no
