The guns were elevated or depressed by means of handspikes and quoins. Quoins were blocks of wood, square, and wedge-shaped, with ring-hooks screwed in them for the greater ease of handling. Two of the gun's crew raised the base of the cannon upon their handspikes, using the "steps" of the gun carriage as their fulcra. A third slid a quoin along the "bed" of the carriage, under the gun, to support it at the required height. The recoil of the gun on firing, was often very violent, but it was limited by the stout rope called the breeching, which ran round the base of the gun, from each side of the port-hole, and kept it from running back more than its own length. When it had recoiled it was in the position for sponging and loading, being kept from running out again, with the roll of the ship, by a train, or preventer tackle, hooked to a ring-bolt in amidships. In action, particularly in violent action, the guns became very hot, and "kicked" dangerously. Often they recoiled with such force as to overturn, or to snap the breeching, or to leap up to strike the upper beams. Brass guns were more skittish than iron, but all guns needed a rest of two or three hours, if possible, after continual firing for more than eight hours at a time. To cool a gun in action, to keep it from bursting, or becoming red-hot, John Roberts advises sponging "with spunges wet in ley and water, or water and vinegar, or with the coolest fresh or salt water, bathing and washing her both within and without." This process "if the Service is hot, as it was with us at Bargen" should be repeated, "every eighth or tenth shot." The powder in use for cannon was called Ordnance or Corne-powder. It was made in the following proportion. To every five pounds of refined saltpetre, one pound of good willow, or alder, charcoal, and one pound of fine yellow sulphur. The ingredients were braised together in a mortar, moistened with water distilled of orange rinds, or aqua-vitae, and finally dried and sifted. It was a bright, "tawny blewish colour" when well made. Fine powder, for muskets or priming seems to have had a greater proportion of saltpetre. The Naval Tracts of Sir W. Monson, contain a list of the sorts of cannon mounted in ships of the time of Queen Elizabeth. It is not exhaustive, but as Robert Norton and Sir Jonas Moore give similar lists, the curious may check the one with the other.
