 ject from the piece, and by which it is 

 supported upon its carriage. Dolphins, 

 two handles placed on the second rein- 

 force-ring of brass cannons, resembling 

 the fish of that name; they serve for 

 mounting and dismounting the guns. 

 The second reinforcc-ring and ogee are the 

 two ornaments joining the trunnions. 

 Ihechace- astragal and fillets, the two last- 

 mentioned ornaments jointly. The 

 muzzle-astragal and fillets, the joint orna- 

 ments nearest the muzzle. The muzzle 

 mouldings, the ornaments at the muzzle 

 of a piece. The su-elling of the muzzle, the 

 projected part behind the muzzle mould- 

 ings. The mouth of a cannon, the entrance 

 of the bore, or the hollow part which re- 

 ceives the charge. The vent, that which, 

 in small fire-arms, is called the touch-hole, 

 a small hole pierced at the end, or near 

 the end, of the bore or chamber, for the 

 purpose of priming the piece with pow- 

 der, or to introduce the tube in order 

 when lighted to set fire to the charge. 

 The chamber is the place where the pow- 

 der is lodged which forms the charge. 

 The tools employed in the use of cannon 

 are as follow: Quoins, or wedges, to lay 

 under the breech of the gun in order to 

 elevate or depress it. Handspikes, which 

 serve as levers to move and lay the gun. 

 Ladles, which serve to load the gun 

 with loose powder. Rammers, which 

 serve to ram home the wads put upon the 

 powder and shot. The sponge is fixed at 

 the opposite end of the rammer, and 

 serves to clean the gun after it has been 

 fired. Screw* are used to field-pieces in- 

 stead of quoins, by which the gun is kept 

 to the same elevation. The searcher is an 

 iron hollow, at one end, to receive a 

 wooden handle, and, on the other end, 

 has from four to eight flat springs pointed 

 and turned outwards at the ends. The 

 reliever is an iron flat ring with a wooden 

 handle at right angles to it : it is so called 

 because it serves to relieve or disentangle 

 the searcher, when any one of its springs 

 is caught in a hole, on its being introduced 

 into the piece to search it after it is fired.
