MINUTES OE PROCEEDINGS OF 
Large Gun . 
“ The larger gun (Plate, fig. 1) is on the south side of the gate. 
“It is 19 inches in calibre, and 12 ft. in total length, of which the 
chamber composes more than one-fourth. 
“The granite balls, of which several lie about, are about 18in. diameter. 
“ The general construction is evidently similar to that of the smaller gun, 
but the bars and hoops are not so distinctly visible. The internal longi¬ 
tudinal bars are about 3 in. wide. The hoops are visible round the back end 
of the barrel. 
“The breech chamber piece consists externally of 10 longitudinal bars, 
the construction being evidently similar to that of the smaller gun. 
“ The muzzle of the gun is somewhat ragged, and has no projecting rings 
like the small gun. Possibly a piece may have been carried away. 
“There are no eyes or rings; there is a trace of a projection where one 
of the eyes may have been, but I find nothing corresponding to it on the 
opposite side.” 
Small Gun e 
“ The smaller gun is on the north or left-hand side of the doorway. 
“ The dimensions will be seen from the accompanying Plate, fig. 3 ; it is 
15 inches in calibre, and 11 ft. 9 inches in total length. 
“ The granite ball is rough in shape, about J or an inch less in diameter 
than the calibre. 
“ The construction of the barrel is quite clearly visible. It is formed of 
wrought-iron, being in fact a true f built-up 9 gun. The inside is made up 
of longitudinal bars, each about 2Jin. wide by 1 in. thick, and round the 
outside are seen the lines of hoops, each about 2f in. wide, placed quite 
close to each other. It is not possible to discover whether the hooping is 
single or in several layers. 
“ The exterior of the breech or powder chamber consists, not of hoops, 
but of longitudinal bars , as shewn in the Plate, their flat surfaces giving 
to it the section of a polygon. This would seem exceedingly weak, but the 
longitudinal marks on the exterior are perfectly distinct, and there is not the 
slightest trace of any hooping. The construction of this chamber and of the 
breech end of the barrel, are obscure; I examined the parts as carefully as 
possible, but without gaining anything towards an explanation. The hoops 
are quite distinct on the commencement of the barrel, as shewn on the 
Plate, and this made me suspect, before examining the interior, that the 
breech-piece was solid, and the powder placed in the barrel, like modern 
guns. But on clearing the inside, the chamber appeared. 
“ The gun has an eye on each side for a ring; and one of the rings, a split 
one, is still there, as shewn in the Plate. The other eye is broken, and 
the ring gone. The eyes appear to have formed one mass with the hoop 
encircling the gun at that place. 
“ The powder chamber of this gun appears shallower than that of the
