leared they went on to Hightown, where they stopped with Grace's cousin.

"And now for the camp!" exclaimed Betty, one morning, when they were
headed for Cameron, where a half-brother of Mr. Ford maintained a sort of
resort, containing bungalows, and tents, that he rented out. It was near
a little lake, and was a favorite place in summer, though the season was
too early for the regulars to be there. Mr. Ford had written to Harry
Smith, his half-brother, and arranged for the girls to occupy one of the
bungalows for several days. Mrs. Smith agreed to come and stay with them
as company.

"Though we don't really need a chaperon," laughed Grace. "I think we can
look after ourselves."

"It will be better to have her at the bungalow," said Betty, and so it
was arranged.

Betty had written to the railroad company, asking if any report of a
lost sum of money had been received, and the answer she got was to

"That leaves the five hundred dollar mystery as deep as ever," she said,

"I'll write home and ask Will to come," said Grace. "He might like to
spend a few days here, and Uncle Harry said he could take a tent if
he liked."

"Ask Frank Haley, too," suggested Amy.

"And Percy Falconer!" added Mollie, with a sly glance at Betty.

"Don't you dare!" came the protest.

"I meant Allen Washburn," corrected Mollie.

"He can't come--he has to take the bar examinations!" cried Betty,
quickly.

"How do you know?" she was challenged.

"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 Blackfo
