GUNNERY IN. 1651.

The 3rd experiment was with a whole cnlverin in brass, 5300 lbs. in 
weight, lift. 1 in. in length, with a taper bore. The iron bullet was 
18 lbs. in weight; the powder in the 1st trial 10 lbs., in the 2nd 9 lbs., 
in the 3rd 8 lbs., which last proportion did the best execution, and 
passed thro 5 the 2 first butts, entering gently into the 3rd, which the 
former two did touch but did not enter. 
The 4th experiment was with a whole culverin in brass, made at 
Amsterdam for the French, with this mark, 3580, being 10 ft. long, 
and not very thick in the breech. „ 
The 1st shot, with 9 lbs. of powder, 18-lb. bullet of iron, passed 
thro 5 the 3 butts, and entered one foot into the ground. It passed by 
the joints of the timber, 2 planks having been bent down before. 
The 2nd shot, with 8 lbs. of powder, passed thro 5 2 butts, and grazed 
between them. 
The 3rd, with 8 lbs., passed the two butts, and 7 ins. into the 3rd; 
but the 1st butt was much shattered before where it entered. 
The 4th shot passed, with 8 lbs. of powder, 2 butts, and in both 
butts passed thro 5 the midst of a massy strong beam below that had 
not been battered. 
The 5th experiment was with an iron demi-culverin, having a 9-lb. 
bullet in iron, and 4 lbs. of powder. This passed one butt which was 
torn before, and entered the 2nd. 
This half-culverin was shot eight times, as fast as they could charge 
it with powder and the iron bullett, and yet was but scarce lukewarm 
at the breech, a little more in the midst, most at the muzzle, and this 
last scarce so hot as my hand, and yet the gunners in charging her wet 
not at all the scoop or spunge. 
The 6th experiment was with a brass demi-culverin. The breech 
of her was 13 Jins., tried with a caliper compass, the mouth 2fins. 
The first shot, with 4 lbs. of powder, 9-lb. iron bullet, passed two butts; 
the 2nd shot, with 3 lbs. of powder, passed almost two butts. 
This proved to be the best shot, because the timbers were strongest.
