The hand-mortar for throwing grenades are said to have been first used in 1594, and gave origin at a later date to the troops thence denominated, _grenadiers_. They appear to have been fired from the shoulder. (Plate 19, fig. 3.) In the reign of James II., a flint-lock-musket was adapted to fire grenades from the butt, the small of which was made to resemble a chambered mortar; the heel of the butt formed a cover, which opened with a spring on a hinge; the priming was put into the usual pan, and a small piece of metal moved so as to open a communication with the powder in the chamber. A rest was formed by a slender iron rod, about three feet long, and when not required let into the stock, in the place usually occupied by the ramrod, and turning upon a pivot placed a few inches in front of the guard-brass. The scouring rod is run through metal loops on one side of the stock. Afterwards grenades were thrown by hand, the musket being slung over the soldier’s back, and more recently experiments were made with an iron tube about four inches long, placed on the muzzle in the same manner as the bayonets. ~Match-locks and rest, James I.~ In the time of James I., part of the infantry were armed with calivers or muskets and rests, both of which were fired with match-locks, the soldier carrying the match lighted at both ends. ~Trickerlock, 1629.~ “A match trickerlock compleat,” occurs in a schedule of 1629. This was the adoption of what is now called a hair trigger, which was added to the former one, and gives a more instantaneous discharge. A tricker wheel lock of Charles I., a tricker match-lock of Charles II., and a tricker fire-lock of James II., are preserved in Sir S. Meyrick’s collection. ~Fowling pieces.~ The Earl of Albermarle in 1646, says, “It is very fit likewise that you have in each company six good fowling pieces, of such a length that the soldier may well be able to take aim and shoot off at ease; being placed six on each flank of a division of foot to skirmish with an enemy. These soldiers ought to have command, when they come within distance, that they shoot at officers only.” We have here plainly the origin of riflemen. ~Tin tube for match.~ ~First fire-lock.~ Each musketeer formerly carried a tin tube, pierced full of holes, to contain the match, and prevent his being discovered; in wet weather it was necessary to carry it in the crown of his cap, to prevent it from being extinguished. One of the earliest attempts to overcome this difficulty is in the Arsenal, at Dresden, where there is an old _buchse_, with a piece of pyrites fixed opposite to the touch-hole, and which requires to be rubbed with a file, chained to it, until sparks are elicited sufficient to fire the powder. ~Snaphaunce.~
