"It wasn't Pompton's fault at all!" cried King, indignantly. "My sister came out here to wait for us, and of course she's around here somewhere. She must be in one of the tents. May we go and look for her?"

"Sure! Go where you like. I s'pose she's pokin' around somewhere to see what's goin' on."

"Of course she's in one of the tents," said Kitty, brightening at the idea. "Where shall we look first, King?"

Just then the man named Bill came along.

"Hello, youngsters," he said. "Lookin' fer that kid sister of yours? She told me to tell you where she'd gone, but, bless my soul, I forgot all about it!"

"Oh, where is she?" cried Kitty, clasping her hands, and looking up at
Bill with pleading eyes.

"There, there, little one! There ain't no use gettin' weepy about it.
Sister's all right. She just went in that there tent with Mademoiselle
Cora."

Bill pointed to the tent, and King and Kitty made a dash for it.

They fairly burst in at the door, and sure enough, there was Marjorie sitting on a big packing box, watching a little girl who was performing most remarkable athletic feats.

"Oh, hello," cried Marjorie, "I'm so glad you've come! Just sit down here beside me, and watch Vivian. Mademoiselle Cora, this is my brother and sister."
