Mona was silent. She was looking a little troubled. Then she turned suddenly to Jill—
"Is this where you brought Mr. Arnold the other day?"
"I found him here," said Jill. "He was a trespasser. That's why he gave me five shillings."
"What have you done with it?"
"I've put it into our bag. Miss Falkner made us a red bag and all our tenth goes into it, and then I take it to Mr. Errington, and he's going to build a mission church on Chilton Common with it!"
Mona gasped, then she began to laugh.
"Hopeful Mr. Errington! I admire his ambition, but I fancy many years will roll by before that church is built!"
"I knew you would laugh," said Jill reproachfully.
"Well," said Mona, looking first at Jill and then at her pile of stones, "I always did say you children had the bump of invention. But I, with Mr. Arnold, will plead guilty of the charge of trespassing; and you must do the same, Captain Willoughby. What will you fine us, Jill? Five shillings? I think we cannot escape with less than that."
