"He wrote—" and then Betty blushed and stopped. Her companions laughed and teased her unmercifully.

There was some mail for the girls awaiting them at Mr. Smith's house, having been forwarded from Deepdale. And Betty's letter contained a surprise. Among other things, her mother wrote:

"There have been some inquiries made here about the five hundred dollar bill. Down at the post-office the other day a man came in and posted a notice, saying he had lost such a sum of money somewhere in this part of the country. His name is Henry Blackford, and the address is somewhere in New York State. It was on the notice, but some mischievous boys got to skylarking and tore it off. Your father is going to look into the matter."

"Oh, maybe he'll find the owner of the money, after all!" cried Mollie.

"Maybe," returned Betty.

CHAPTER XXII

A PERILOUS LEAK

The boys came to the camp at Cameron—Will, Frank—and, as a surprise—Allen Washburn. Betty could hardly believe it when she saw him, but he explained that he had successfully passed his bar examinations, and felt entitled to a vacation. Will had invited him on the receipt of his sister's letter.

"And we'll have some dandy times!" exclaimed Will.

"What about the man looking for his five hundred dollars?" asked Grace, for her brother and the other boys knew of the find, and also of the notice put up in the post-office.
