t of shadow," grinned Hiram Nelson, who,
besides Paul Perkins, was the inventive genius of the Eagles.

The scene of these reminiscences was the comfortably furnished patrol
room of the Eagles, situated over the bank of the little town of Hampton
on the south shore of Long Island. Rob Blake's father, the president of
the bank, was a patron of the Eagles, and had donated the room to the
boys some time before.

Boxing gloves, foils, baseball bats and other athletic apparatus dear to
a boy's heart lay scattered about the room in orderly confusion. On the
walls were diagrams of the "wig-wag code" and the "Morse code
simplified," with other illustrations of Scout activities.

But it was above the door that there was perched the particular pride of
the Eagles' hearts--a huge American eagle, a bird fast disappearing from
its native haunts. With outstretched wings and defiant attitude it stood
there, typifying the spirit of its young namesakes. The eagle had been a
present to the lads from Lieutenant Duvall, of the United States Army,
whom they had materially aided some time before in various aerial
intrigues and adventures. What these were was related in full in the
"The Boy Scouts and the Army Airship."

In the first volume of this series, "The Boy Scouts of the Eagle
Patrol," it was told how the boys came to organize, and how they
succeeded in unravelling a kidnapping mystery, involving one of their
number. In the second volume, "The Boy Scouts on the Range," we followed
the boys' adventures in the far southwest. Here they encountered Moqui
Indians and renegade cow-punchers. But through all their hardships and
adventures they conducted themselves according to the Scout laws.

The third volume was "The Boy Scouts and the Army Airship," referred to
in connection with Lieutenant Duvall. In this book a military biplane
played an important part, as did the theft of a series of plans of a
gyroscope invention of Lieutenant Duvall's, who was an all-around
mechanical genius.

In the story that preceded the present account of the Eagle Patrol the
lads found themselves in the Adirondacks on a strange mission. With a
certain Major Dangerfield, a retired army officer, they searched for a
lost cave in which an old-time pirate, one of the Major's ancestors, had
hidden his loot when Indians threatened him. How the cave was located
and the startling discovery made there, we have not space to describe
here. But in the wildest part of th
