CHAPTER I

A PACKAGE VANISHES

"Good night!" exclaimed a lad of about eighteen peering from the window
in a railway coach. "This train's running on a regular lake!"

"What's that, Jimmie?" asked a companion approaching the first speaker.
"Are we on a ferry? I still feel the wheels hit the rail joints."

"Oh, yes, now and again we crawl along a rail's length or two," admitted
the boy, "but it's mighty slow work! I'm getting tired!"

"What place is this, anyway?" inquired a third boy coming to the window.
"It looks as if we're going out into the ocean!"

"We can't be headed for Holland at this rate!"

"We surely are!" assured the one addressed as Jimmie. "I'll bet I can
tell you what that is! The Belgians cut their dikes and flooded the

A general laugh greeted this assertion. Moving about in the limits of the
none too commodious compartment of a European railway carriage four boys
dressed in the well-known khaki uniforms of the Boy Scouts of America

To those of our readers who have followed the adventures of this group of
boys as related in the previous volumes of this series no introduction is

Just now they were practically prisoners, having been accorded passage
from the German lines to a neutral port in Holland, where they expected
to take ship for their home town of New York.

Ned Nestor, a fine, manly lad, was the Leader of the Wolf Patrol of New
York City, Boy Scouts of America. He had been often selected for
difficult work by the Chief of the United States Secret Service because
of his aptitude for the work. His coolness and sound judgment had carried
himself and his companions through many difficulties. It was a mission of
this character upon which the boys had recently engaged and from which
they were now returning.

Jimmie McGraw, freckle-faced and red-headed, was a member of the Wolf
Patrol of which Ned was leader. He was an ardent adherent of Ned's.
Brought up a newsboy on the Bowery of New York the boy had come under the
