It is said of the cross-bow that a _quarrel_ could be projected from them 200 yards, so that we may imagine the force with which one of these lumps of iron would strike even the strongest armour,--as the velocity, to range that distance, would not be far short of 900 or 1,000 feet per second; nearly equal to the effect of a ball from one of our old imperfectly constructed muskets. We are told incredible stories of the abilities of some of our bygone archers. Should it be true, as stated, that an arrow could be shot nearly 700 yards, we can easily conceive the immense velocity with which it must have left the bow; this range being quite equal, if not superior, to that of the late unimproved rifles. Though we must bear in mind, that the peculiar shape of the arrow fits it to cut the atmosphere with less resistance then the half sphere of a bullet; and hence one reason of its obtaining an extensive range. There is a story told of the famous Robin Hood, and Little John, “who could shoot an arrow a measured mile.” We suppose the mile was the reverse of an Irish one, or they had the advantage of a precious stiff gale of wind. Historians sometimes “draw the long-bow” as well as archers. Many statements have descended to us of the power of the battering rams of old; but we have a much more ready method of blowing open gates by a single bag of gunpowder; and a 68 lb. shot has all the force that could be given even to that famous ram of Vespasian, “the length whereof was only fifty cubits, which came not up to the size of many of the Grecian rams, had a head as thick as ten men, and twenty-five horns, each of which was as thick as one man, and placed a cubit distance from the rest; the weight, as was customary, rested on the hinder part, and was no less than 1,500 talents; when it was removed, without being taken to pieces, 150 yoke of oxen, or 300 pairs of horses and mules, laboured in drawing it, and 1,500 men employed their utmost strength in forcing it against the walls.” With these remarks we shall proceed to introduce the invention of Gunnery. Barbour, in his life of Bruce, informs us that guns were first employed by the English at the battle of Werewater, which was fought in 1327, about forty years after the death of Friar Bacon; and there is no doubt that four guns were used at the battle of Cressy, fought in 1346, when they were supposed to have been quite unknown to the French, and tended to obtain for British arms the victory. Froissart gives an excellent representation of a cannon and cannoneers, in 1390, a cut of which we give in the following page.
