Ammunition in Reserve. 
Double shell, lined like common with red lacquer. 
Weight, empty. . 13 lbs. 7 oz. 1 
Bursting charge . 1 lb. L.G. powder, j 
Length . 13*2 inches. 
Total 14 lbs. 
7 oz. 
These shells in spite of their great length, low velocity, and high angle 
of elevation at vertical fire, keep point first. Two burst flew into 47 and 
48 pieces. 
Cartridges. Bed shalloon, hooped with one hoop of blue worsted braid 
choked with worsted containing a charge of 3 oz. T.G. powder in paper 
covers. 
They accompany the double shell, and are intended to be reduced as 
required. 
Fuzes K Y§-seconds, painted like the 10 seconds and the M.L.O. fuzes, and 
has the same fine grain powder channels; it is driven with slow composition 
burning at the rate of 1 inch in 7^ seconds, each hole reads for 1J tenths 
fuze composition, and is so marked. 
N.B.—The fuze hole of the above shells being the common gauge tapped 
throughout, the following fuzes might be tried on an emergency :—- 
Time. Boxer’s common, diaphragm, and small mortar. 
It is not certain how they would act, but they might be tried. 
Percussion fuzes . It has been found that the time fuzes supplied with 
the shells act as percussion fuzes, being driven in on striking, and no 
percussion fuzes have been sent. If required, Pettman’s land service fuze 
might be tried with the common and double shell, and possibly the general 
service would be found to act also, as it screws in for the greater part of its 
length. 
The boxes containing the ammunition are cedar, covered with canvas, the 
strong threads of the canvas running across the fibres of the wood so that the 
former and latter should naturally not tear and split in the same direction. 
These boxes are made small enough to carry by hand if necessary, the 
four on the mules sides each contain two common shell, two shrapnel shell, 
and one case shot. They are placed as shewn in sketch. 
Rochets , Q-pr. IIales\ 
Weight ...... 8 lbs. 7 oz. 
Length . 16*2 inches. 
These rockets, like the other calibres of Hales* rockets, are fired without 
sticks, being kept point first in flight by rotation given on the turbine 
principle, that is, by the pressure of gas escaping from the vents in the
