Lt. Col. B. M. Bryan,
Chief, Aliens Division,
Office of The Provost Marshal General,
War Department,
Washington, D. C.
1. In accordance with request, checked over subject with Capt.
Grohme, Assistant District Engineer of theSixth Corps Area. Capt.
Grohme has had charge of the design and installation of all recent con-
struction of this stocade.
2. Inclosed herewith are three blueprints, as follows:
&. Ground plan of the McCoy enclosure.
k. Detail of stockade guard towers.
a. Small plan of stockade fence construction.
3. As noted in red on the blueprint, the sentry houses on the
guard towers have recently been corrected so that the floor of the
house is not less than 6 feet above the top of the fence, of a minimum
of 14 feet above the ground.
4. The two chain wire fences are constructed continously around
the entire enclosure with only two gate openings:
a. Distance between fences approximately 30 feet.
. Heighth of chain fence, 7 feet - increased to
8 feet by the extension arm for carrying the
barbed wire strands.
£. The chain fence goes to the ground, but has no
s sub-surface countersinking. Where small
depression occurs along the lineof the inner
fence, barb wtte strands have been strung to
block the resultant small gaps between the
fence and the ground. This applies only to
the inner fence.
. The angle arms carrying barb wire are canted
inward toward the enclostre on the inner f       -   .:  '
fence, - and are canted outward on the outpr
fence.
