the entreaty.
"He is worth a fortune! Don't harm him!"

There was a commotion--a scramble. Several men stumbled and fell, and
from their midst a figure dashed--a figure at the sight of which a
gasp of astonishment came from the three Motor Boys.

And since Ned, Bob and Jerry have been called Motor Boys several times
I will take just a moment here to tell who these lads were and
something about them; also why they were at Camp Dixton. Of course,
the readers who already know this may skip what immediately follows
and proceed with the story.

As related in the initial volume of the first part of this series, a
book which is named "The Motor Boys," Ned Slade, Bob Baker and Jerry
Hopkins were chums of long standing. They lived in Cresville, not far
from Boston, and the three lads were well-to-do. Jerry's mother was a
wealthy widow, while Bob's father was a banker, and Ned's a department

In the books succeeding the initial volume are related the various
adventures of the Motor Boys, who journeyed to Mexico, across the
plains, and traveled much on the Atlantic and Pacific, both in craft

the only change in the stories was in the title, for the main
characters were still the "Motor Boys."

The parents of the lads felt that they ought to do some studying, and,
accordingly, Ned, Bob and Jerry were sent to Boxwood Hall. What took
place there formed not only a well-remembered part in their lives, but
furnished some excitement as well. When vacation came they went to a
Western ranch and had fun, as well as helped in an important piece of
work.

And then came the Great War.

Our heroes could do nothing less than enlist, and in the volume called
"Ned, Bob and Jerry in the Army," which immediately precedes this one
you are reading, is told something of their life at Camp Dixton, one
of the training camps in the South.

There the chums had learned to become s
