THE sECRETARY'S ORDER.
"In view Of the great value of the
information that may be obtained re-
garding the effect Of bombs and gun.
FIRE on vessels Of comparatively res
cent design, every effort should be
made to obtain the maximum amount
of useful information from these ex- z
erciseA," states the order from the
Secretary of the Navy.
IF during the bombing test 10
should develop that more profitable
information might be obtained from
exploding bombs on turret tops,
alongside the turrets or coming
tower or in any other special loca-
ton, it is desired that this be done BY
static explosions. II aircraft adds
tional to those available In the air
force are considered necessary, rec- I,
cmmendation of the classes ana !,
number is requested. and effort wils

"Observe and report the number ana

from which each bomb is dropped ana
its point of fall. .,.
Conserve and report the action Of

fort and damage to the ships, bearing
in mind the age Of the ships, their
state of preservation and their date

ings:
"U) Probable damage to personnel
"(2) Damage to A, A. guns and de- !
lenses. and to light equipment ana
structure exposed on the topsides.
"(3) Damage to the main lighting
equipment particularly lighting and
control systems), and to the main
structure of the ship.
Make such deductions as can
reasonably be made, based on the
consideration of facts as to proba ble

designs and good state OF preserves
