Other firearms in use in our ships at sea were the matchlock musket, firing a heavy double bullet, and the harquabuse[21] or arquebus, which fired a single bullet. The musket was a heavy weapon, and needed a rest, a forked staff, to support the barrel while the soldier aimed. This staff the musketeer lashed to his wrist, with a cord, so that he might drag it after him from place to place. The musket was fired with a match, which the soldier lit from a cumbrous pocket fire-carrier. The harquabuse was a lighter gun, which was fired without a rest, either by a wheel-lock (in which a cog-wheel, running on pyrites, caused sparks to ignite the powder), or by the match and touch-hole. Hand firearms were then common enough, and came to us from Italy, shortly after 1540. They were called Daggs. They were wheel-locks, wild in firing, short, heavy, and beautifully wrought. Sometimes they carried more than one barrel, and in some cases they were made revolving. They were most useful in a hand-to-hand encounter, as with footpads, or boarders; but they were useless at more than ten paces. A variation from them was the hand-cannon or blunderbuss, with a bell-muzzle, which threw rough slugs or nails. In Elizabethan ships the musketeers sometimes fired short, heavy, long-headed, pointed iron arrows from their muskets, a missile which flew very straight, and penetrated good steel armour. They had also an infinity of subtle fireworks, granadoes and the like, with which to set their opponents on fire. These they fired from the bombard pieces, or threw from the tops, or cage-works. Crossbows and longbows went to sea, with good store of Spanish bolts and arrows, until the end of Elizabeth's reign, though they were, perhaps, little used after 1590. The gunner had charge of them, and as, in a way, the gunner was a sort of second captain, sometimes taking command of the ship, we cannot do better than to quote from certain old books concerning his duties on board. Mr W. Bourne, the son of an eminent mathematician, has left a curious little book on "The Arte of Shooting in Great Ordnance," first published in London, in 1587, the year before the Armada. Its author, W. Bourne, was at one time a gunner of the bulwark at Gravesend. The art of shooting in great guns did not improve very much during the century following; nor did the guns change materially. The breech-loading, quick-firing guns fell out of use as the musket became more handy; but otherwise the province of the gunner changed hardly at all. It is not too much to say that gunners of Nelson's time, might have studied some of Bourne's book with profit. [Footnote 21: or caliver.]
