of one of the highest peaks in the Berkshire hills, where the four
girls and Miss Sallie spent a happy period of time "roughing it." There
it was that they discovered an Indian Princess and laid the "Ghost of
Lost Man's Trail."

In the third volume of the series, "The Automobile Girls Along the
Hudson," the quartet of youthful travelers, accompanied by Miss Sallie
Stuart, motored through the beautiful Sleepy Hollow country, spending
several weeks at the home of Major Ted Eyck, an old friend of the
Stuarts. There many diverting experiences fell to their lot, and before
leaving the hospitable major's home they were instrumental in saving it
from destruction by forest fires.

dark rumors afloat to the effect that she was an impostor and how she
afterwards turned out to be a princess, is fully set forth in "The
Automobile Girls at Palm Beach."

"Really, Bab," said Ruth, as the two girls went upstairs to their rooms
to dress for dinner, "I have not had a chance to talk to you, alone,
since we arrived in Washington. How is your mother?"

"As well as can be," Bab answered. "How is darling Aunt Sallie? I am so
sorry she did not come to Washington with you to chaperon us. There is no
telling what mischief we may get into without her."

Ruth laughed. "I have special instructions for the 'Automobile Girls'
from Aunt Sallie. We are to be particularly careful to mind our 'P's' and
