MINUTES OF PROCEEDINGS OF 
( e ) Cartridges. 
The low-angle cartridge is intended for firing with a flat trajectory; it is 
a bag of woollen stuff, and contains 7*4 oz. of ordnance powder. 
The high-angle cartridge is used in firing with a highly curved trajectory; 
the bag is like the former in material, but contains only 3*9 oz. of 
ordnance powder. 
The exercising and saluting cartridges are used as prescribed by their 
denominations. 
All cartridges are marked in oil colour, with indication of their calibre 
and nature. 
Ammunition boxes and packing. 
5. The boxes for packing the 3-pr. ammunition (Fig. 16) are strength¬ 
ened with iron clamps; internally the space is divided into three 
compartments by wooden partitions. The method of packing varies. 
The compartments a and c contain either 4 common shells each, and the 
central compartment b , 8 low and 4 high-angle cartridges and 1 bundle 
of friction tubes; or in a and c , 4 shrapnel shells each, and in b } 8 low- 
angle cartridges and 1 bundle of friction tubes; or lastly, the compartments 
a and c, each contain 4 case shot, and the compartment b 3 8 low-angle 
cartridges and 1 bundle of friction tubes. 
The projectiles encased in their canvas bags are packed base downwards; 
the cartridges in two layers, the length of the cartridge in the direction of 
the length of the box. 
The 3-pr. ammunition box filled with common shell weighs 76*5 lbs.; 
with shrapnel shell, 77’8 lbs.; and with case shot 65*4 lbs. 
Special packing bags and ordinary cartouches are used for packing 
baggage, spare materiel } and rations. 
Gun implements and other articles of equipment. 
6. The 3-pr. gun implements and articles of equipment are as follows ;— 
Tompion and vent cover both with buckling straps, sponge with rammer, 
drill sponge, handspike, fuze spanner with sling, binocular glass, specially 
intended for officers' use, priming iron and vent bit, tangent scale and vent 
bit case, tube pocket, cartouche, vent drift and hammer, canvas bag hooks, 
clasp knife with sling, kneecap, recoil rope, friction tube lanyard; finally 
pickaxe and shovel, lashing line, mule picket, cooking utensil, and drink 
ke g. 
Of the above-named articles, only those whose construction are least 
known will be described. 
The tangent scale (Fig. 17) is of brass, and is constructed so as to give at 
the same time the elevation and the allowance for permanent deflection or 
derivation to the right, consequent on the rotation of the projectile. The 
tangent scale consists of the base p, with its lug o } the upright bar s , and 
the slider u movable up and down the bar; the cross-bar g, with an upper 
and lower V notch, traversing at right angles to the upright bar in a slot in 
the slider.
