\ saw this morning the model of floating battery
which think far surpasses your famous work in every
respect. The invention is a creation of Mr.. Gamble
well known in Georgia a very scientific gentleman
The model and explanation of it has met with so much
favor at the department that inclined to think
it will be experimental upon in the Chesapeake Bay
before Fortress Monroe The following is an accurate
description of the work. which had partly promised to
keep quiet but supposing it would be published else
where subjoin it. You will find it very interesting

CANDLES ROTARY FLOATING BATTERY.


" This model is constructed a scale OF oneeighth
of inch to the foot 1t is calculated carry at least
thirty guns of heaviest metal though present pierced
forOuly ten The Battery will be constructed of iron
shot and bomb proof the thickness of the iron and the
size OF the guns depending upon the locality in which it
is to operate. For instance in some shallow harbors
1t IS obvious that no large ship with heavy arma
ment, can enter but these Batteries can carry the
heaviest armament even in shallow waters it is plain
that they destroy with impuny their lighter armed
adversares before the latter can arrive in effective
range for their lighter guns In such cases great de-
ducton may be made in the weight of the iron employ
ed in their construction By inspection of the model
it will be that it is surrounded by breastwork or
breakwater also shot proof rising but little above the
water. This barrier at least the threeod pur-
pose of protection to the hull of the Battery pro-
vision against boarders from boats and preserver of
smooth water under the muzzes of the guns When
properly poised the Battery will present an acute angle
to the enemys fire, causing the shot to pass harmssy
over or under.


"The magazine in the centre, is furnished with a
bombproof roof the apex of which will to assist
the support of light floor, roof covering the whole
space within the battery circle This floor will not offer
resistance to heavy bombs falling upon it, but will per-
nit them to fall through into the water beneath the
same time it furnishes parade for the garrison and
commodlous deck for small armed men and even field
pieces and morars On the centre of this floor is cir
cular tower shotproof in which to be posted the
gunners who to discharge the guns which in roa-
ton brought to bear upon the target This is pro-
posed to be done by electricity their position giving
them peculiar advantages for correct am free from the
observation of smoke and having full view of the hor
lion. like protection for small-armed men from the
fire of ships tops be constructed around tie
edge of this deck, from which an nCessant fire OF mus
kerry could be maintained.


Passing down through the centre of the magazine
is pivot, which the whole Rotary Battery will turn
while in action. Ifit be desirable to maintain the exact
position, this at the same time anchor and

By simple contrivance, the Rotary be made to

or manual labor. The magazine is rendered accessible
to the batteries by two covered ways having open gra

The guns designed to work in slides similar to the
movement of what is called the head in high pressure

Directly over each gun is small flag staff by its color

own portfolio by its own action. Each Rotary is fur

out OF the way of the guns and protected from injury
from any external cause These engines, working in
parallel lines, will carry the Rotary from point to point

"The Rotary be furnished with movable keels or
centreboards to enable her to currents, if
desired, without making leaway. When desirable the
heavy guns can be withdrawn, without removal from
the Rotary and lighter guns substituted, making the
armament homogeneous. In the present model, the
heavy guns are mounted in the angles, say three 100
Founders and three 80pounders Being Of the simplest
possible construction, the whole be made by

will give revolution every five minutes, and gun
