been a mystery about her past which had recently been cleared up, and
it may have been this mystery that caused the girls to treat her with
a little more consideration and gentleness than they did each other.
Her guardian was a broker in the city who knew very little of the past
except through letters.

The four boys who were close chums of the girls and had added to the
interest and excitement of more than one of their adventures were
Allen Washburn, who was very much interested in Betty, and in whom
Betty was very much interested; Will Ford, Grace's brother, who had
carried Amy Blackford's picture all through the war; Frank Haley, Will
Ford's closest chum, and Roy Anderson who had not much distinction of
any kind except that he was "lots of fun" and a chum of the other
three boys.

In the first volume of this series the girls went on a camping and
tramping tour, tramping for miles over the country and meeting with
many adventures on the way.

Later they had more fun at Rainbow Lake, in a motor car, in a winter
camp, in Florida, at Ocean View, then at Pine Island where the girls
and boys together had cleared up a mystery surrounding a gypsy cave.

Later the girls and boys found themselves caught in the meshes of the
great war, as many hundreds of thousands of others had been. The boys
responded eagerly to the bugle call, and the girls, too, were eager
for Army service and finally went to a hostess house at Camp Liberty.
Though the girls had never worked harder in their lives, they found
that the task had a stirringly romantic side as well.
