ll. Nothing disturbing had happened.

"Time to get up? Why it just seems as if we'd been asleep a second!"
laughed Kit.

"That's your bad luck, then," exclaimed Joy, "for my watch says it's
after two."

Bet and Kit jumped out of bed, and Bet put her hand on the fan and
patted it.

"It's still safe, girls! I don't think we'll be disturbed tonight."

"Listen to her, Shirley!" yawned Joy. "She's going to say that we can
all go to sleep now that it's her turn to guard the fan."

"Indeed I'm _not_! I have no intention of leaving the fan unguarded.
You forget that I'm on my honor to get this into the safety box on
Monday!"

"Next watch is from half past two to half past six! Run along and get

rooms. Shirley and Joy cuddled down under the covers and were soon
asleep. And when Auntie Gibbs was in her own room, Kit and Bet began
their watch.

At dawn they awakened Shirley and Joy.

"Bet Baxter, you're cheating!" came Joy's sleepy voice from the
blankets.

"I just this minute closed my eyes," exclaimed Shirley.

"Waking us up the minute we fell asleep! A trick like that isn't
funny. You just think it is!" pouted Joy.

The three girls commenced to giggle and soon Joy was wide awake and
enjoying the joke at her expense.

Bet and Kit slept until breakfast time.

"What are we going to do today?" asked Joy as they went down to the
dining room. "Let's think up something specially nice, for school

"Whatever it is that we plan, it will have to be som
