weight of Iheir bullet in grape or bd·flIOt, mayan·

by ten times the number of (mall pieces. See GUN·

NERY .

The author here quoted, has propofed to change

the fabric of all the piem employed in the Britifh navy,

from the tIVenty four pouodm dOIVolVards, fo that

they may have the fame or lefs weight, but a larger

bore. He thioks Ihe thirty·two pouoders io prefeot ufe

would be proper models for Ihis purpo(e. Thefe be·

iog of fifly.tlVO or fifty·three hundred weight, have

fomewhat lefs than a hundred and IWOthirds for each

pound of bullet. Aod that this

pr~portioo

would ao·

fwer in fmaller pieces, in point of llrenglh, feems elear

from thefe conftderations:

l .

That the Ihenglh of iroo

or any other metal, is in proportion to its fubllaoce.

2 .

That Ihe lefi'er quantilY of powder filed io a fpace

it fills, has proportionably lefs force thao a Iarger quao·

tity; fo tha! if

t\Vo

pieces, a large and a (mall ooe, be

made in Ihe fame proportion to their refpeélive bullets,

and 6red witb a proportiooalíle qUántity of powder, the

Iarger piece will be more llraioed, will heat more, and

recoil more than the fmaller.

On this fcheme our prefe"t twenty.four pounders

will be eafed of fix or eight hundred weight of ufeleCs

metal; and fome pieces of a lefs caliber. as nine aod

fix pounders, would be fometimes eafed by fourteen

huodred: hence much larger guns of the fame weight

might be boroe. Thus, inllead of ftx, nine, twelve,

aod eighteen pounders, our fhips l1light carry twelve,

cighteen, and twenty.fuur pounders : guns would be

kept cooler and quieter, and would be of more fervice,

in many refpeBs, if their ufual charge of powder were

diminifhed.

In the tower of Londoo, and olher garri(ons, as

a large powder.horn in a llring over his left fhoulder :

Each fort of ordnance is more or lef! forti6ed ;

which fonification is reckoned by the thicknef, of the

melal at the touch·hole, at Ihe [lunnions, aod at lbe

There are three qegrees ufed in fortifying each fort of

ordnance, bOlh cannons aod culverines: Firll, fueh

fecondly, fueh \VhoCe foni6cadons areleffeoed, WhlCh are

calJed baflard pieces; Ibirdly, double fortified pieces,

or eXlraordinary pietes.

The canoons double fortified have full one diameter of

their bore in tQickoefs of melal at their touch·hole,

and

at their trunnions, and

at their muzlle. The
