The large cannon, which is for great
batteries, usually weighs fifty-five or lx
quintals. At the breech it carries the thickness of
b two balls &l three parts
of one ball the one. At the front, it carries
ba the thickness of one ball &
two three parts the two. It is thirteen or fourteen
panslong. But they are very troublesome to drive. The
head-on battery, to accomplish its task quickly is &
batter with great force, is at d one-hundred fifty
paces & at two hundred. And It is true that one
batters well from three or 4 hundred paces, but it is necessary
to give it more powder. Its common load is p
of xx lb of powder, its ball of 40 lb. One
needs xxv horses to draw it. When one fires it farther than its
usual range, one puts in a half ladle of cannon
powder more. A cannon can be fired
4^(xx) or a hundred shots per
day, but one needs to refresh it every time after one
has fired te nine or ten shots, if the battery is steadily
used. For if there is a break, it is not necessary to refresh it as
often. For two quintals of copper, or two quintals
& a half if it is for large cannons, one puts one
quintal of metal#. The
metal is composed at the beginning of eight lb of
tin for one quintal of rosette, while
for big bells one only puts six lb of fine tin for one
quintal of rosette, to give it a bigger
voice. For the more tin there is, the clearer the
sound is. Its For gun founding, if one provides the
material & charcoal, as one usually does, for
masters do not have the means, one gives x to xii
lb per quintal. And for the mat when the
master provides everything, one gives him 40 lb,
according to the King's ordinance, per
quintal for large pieces & such as cannons, and for
small pieces, L lb . For the more material there is,
the more profit the master has of it. One founds another kind
of cannon-perriers of xxx quintals which are longer than the
others, and easily eight pans long, & they are for
battering defenses & casematess,
placing them via trenches on the edge of the ditchby night.

On each side of the opening of the breech they give the thickness of
half a ball. And then they also add on each side the third part
of a ball.

Ain one gives it two ladles of
cannon powder for its charge, & one & a half ofarquebus powder, & the same for the others.

The composition of French cannons is of one quintal of
metal for two of rosette.
But those of Toulouse &
Poncet puts iii of rosette & one of
metal.



The rosette for re-melting is more profitable than
cauldrons, which turn entirely into filth.



Old pieces are composed of almost de demas much
of one as of the other, namely one part of
rosette & one of metal. One recognises this
composition with a burin. For its substance is found to be sour
& the particle taken from the burin is found to be mixed
with yellow & white.
