"Sue, how would you like to practice sleeping out?"

"Sleeping out?" said Sue. She did not just know what Bunny meant.

"Yes, sleeping out," said the little boy again. "Sleeping out in this tent, I mean. We'll have to do it, if we go to camp, and we might as well have some practice, you know."

Bunny and Sue knew what "practice" meant, for a girl whom they knew took music lessons, and she had to go in and practice playing on the piano every day.

Bunny thought that if you had to practice, or try over and over again, before you could play the piano, you might have to practice, or try, sleeping out of doors in a tent.

"How can we do it?" asked Sue.

"It's easy," Bunny answered. "We'll bring our blankets out here and sleep in the tent to-night."

"Maybe daddy and mother won't let us, Bunny."

"They won't care," said the little boy. "'Sides, they won't know it. We won't tell 'em. We'll just come out at night, when they've gone to sleep. We can slip down, out of our rooms, with our blankets, and sleep in the tent on the ground, just as we'll have to do in camp. 'Cause we mayn't always have cot beds there. Will you do it, Sue?"

"Course I will, Bunny Brown!"
