"Mr. Januth ith troubled," observed Tommy wisely.

"What is it?" demanded the guardian.

"What is it? It's a rock, Miss."

"What do you mean?"

For answer he held out on the palm of one hand a chunk of granite, the while surveying it ruefully. Miss Elting took and examined the rock, then directed a look of inquiry at Janus.

"I don't understand," she said, with a rising inflection on the last word.

"Well, I swum! no more do I!" he exploded. "Will you look into that pack and see what you find? Maybe I can't see straight this evening. Maybe I can't."

Harriet ran to the pack he had indicated and peered into it. She uttered an exclamation, loosened the rest of the binding ropes and turned the contents out on the floor of the Shelter. Exclamations of amazement fell from the lips of the Meadow-Brook Girls. Instead of the supplies that had originally been stowed in the pack, a choice assortment of stones, chunks of granite, small hardheads and pebbles rolled out on the floor. They were speechless for the moment. Janus tugged nervously at his beard, too thoroughly astonished for speech.

"I gueth thomebody hath been throwing thtoneth at uth," observed Tommy Thompson. "I wonder who liketh uth tho much that he wanth to knock our headth off?"

"Open the other packs," directed Miss Elting calmly.
