The Spindle. 
The spindle. The spindle consists of a solid rolled and compressed paper head, 
with a body of the same material, and made in one piece. 
The dimensions of the head are as follows :— 
in. 
Diameter . *8 
Depth . *25 
so that it tits accurately into, and the top of it is flush with, the top of 
the body. 
This head rests on the shouldews formed by the difference in diameter 
of the spindle-head recess and the interior quick-match groove. 
Body of The body of the spindle is cylindrical—

Tamping. The lower ends of both spindle and body are undercut for a length of 
*25 in. to receive the tamping, which may be formed either of a mixture 
of chalk and alum or of pure clay. 
Composition and Priming. 
Fuze com- The composition is contained in the ring formed by the difference of 
position. q-j; ame ^ er 0 f the fuze composition hollow and that of the body of the 
spindle. The breadth of the composition is consequently *1 in., and is 
composed of ordinary fuze composition. 
Driving. The manner of driving the composition is as follows :— 
The fire-holes—which are three in number, and which I previously 
omitted to mention—have a diameter of *25 in. 
The axes of these fire-holes are at right angles to that of the fuze, 
and the holes communicate directly with the interior quick-match 
groove. 
Three stout strands of quick-match are placed in this groove, and 
the six ends brought out through the fire-holes (two ends through 
each hole). 
The spindle is then inserted from the top, and passing through the 
triangular space formed by these three strands, secures the quick- 
match in its place.
