the smoke he had inhaled. They carried the man on ahead to the train and
up to the dining car, after which a doctor was hurriedly summoned from
one of the other cars. In the meantime Barbara had returned to her
companions, who were anxiously awaiting her reappearance. She told them
of finding the man, and was warmly commended by the passengers for her
bravery.

"I do wish we could get word to Ruth Stuart that we are all right," said
Barbara, after she had related the story of the finding of the man from

as will be recalled, that Barbara distinguished herself by causing the
arrest of a society jewel thief, at the same time heaping coals of fire
on the head of a girl cousin who had treated Barbara and Mollie with
scornful contempt.

The girls were next heard from in "THE AUTOMOBILE GIRLS IN THE
BERKSHIRES," to which region, chaperoned, as always, by Ruth's Aunt
Sallie, they had driven in Ruth's car for a month's stay in a lonely
cabin in the Berkshire Hills. Their experiences with the "Ghost of Los
