Summer days passed-- delicious, lazy summer days-- during which the
girls motored, canoed or rowed as they fancied, went on picnics in the
woods, or on some of the islands of Rainbow Lake, or took long walks.
Mr. Stone and Mr. Kennedy, sometimes one, often both, went with the
girls. Occasionally Will and his friends ran out for a day or two,
taking cruises with Betty, and her chums.

Aunt Kate remained as chaperone, others who had been invited finding
it impossible to come. The girls' mothers made up a party and paid
them a visit one day, being royally entertained at the time.

"Yes, you girls certainly know how to do things," said Mr. Stone one
day; after Betty had skillfully avoided a collision, due to the
carelessness of another skipper.

"I wish we could do something to get those papers for father," thought
Grace. Not a trace had been found of Prince or the missing documents.
It was very strange. Mr. Ford and his lawyer friends could not
understand it. The interests opposed to him were preparing to take
action, it was rumored, and if the papers were found this would be
stopped. Even a detective agency that made a specialty of tracing lost
articles had no success. Prince and the papers seemed to have vanished
into thin air.

One day as Betty and her chums were motoring about the lake, having
gone to the store for some supplies, they saw the two boys who had
been searching for their canoe.

"Did you find it?" asked Grace.
