and men in this battery-Battery
e of the Forty-second Artillery,
went to work; and they have been
working ever since. The huge guns
and the 490.0OO,OO0 candlepower
searchlight require as much atten-
ton as a pair of twins.
Tonight will sc some great ac-
tivity by the searchlight. 1t is a
Sperry "self-contained" mechanism.
The searchlight proper is mounted
on a small truck; and this truck, in
turn. is on one of the largest trucks
used by the United States Army
The dynamo which supplies the
searchlight with power is connect
ed with the formidable engines of
the mother" truck.
The searchlight is to be operated
! in several sections of the city.
| City Commissioner E. u. Gross this
morning was of a mind to refuse
| Victory Loan authorities the priv
| ilege of taking the truck into ReSer-
Voir Park because lit would cut UP
the grass" The committee wished
| TO place the truck and light near
the Detweiler statue, so that the
rays of the light might be thrown

The equipment carried by the ar

plane observers talk with the bat
terry and keep the gunners informed
| as to how their shots are falling.
In this car, too, there are to be

range board, a DETECTION board,

there is gathered the data for use
on the guns, and this data is rap
idly computed by a crew of eight
men and communicated to the gun
ners.
What INT Does
There is also an exhibition of pro-
jectiles and high explosives. For
| instance there is a jar containing
eight four-pound containers filled
with INT used in the projectiles. If
a very severe concussion were given
this explosive, the Pennsylvania
freight yards, The Metropolitan an
mex, the Reading station and other
structures in that section would be
no more. Fffty-siX pounds of TINT
are used in shells for the big guns.
A submarine mine is also shown,
and an exhibition of engineering
drawings.
In the bunk car Harrisburg will
be able to see how the men live on
the front. 1t contains a kitchenete
in reality a field stove planted in
a box of clay. This is attra citing

he and the four men with him did It,
All were decorated for their work
