- Sopwith Military Biplane
A machine that has achieved success, owing to its power of varying speed, is the Sopwith military biplane. Adopting a practice that has become general, its wings are fitted upon what is practically a monoplane body. Tail-planes and rudder are the same as in a monoplane. The top main-plane, as will be seen, is set slightly in advance of the lower. The system is called “staggering”; and the idea is that, by placing the upper plane ahead of the lower, the total lifting power will be increased. It has been proved a disadvantage of the biplane that, when the main-planes are placed one above another, there is a slight loss of lift owing to the fact that, acting upon the air as they do quite close to each other, a certain amount of interference occurs between them—one tending to disturb the air-stream in which the other moves. By “staggering” the two planes this interference is overcome; but some makers regard it as a small consideration, and build their planes in the ordinary way, allowing as large a gap as possible between them. In the Sopwith military machine, engine and propeller are in front of the main-planes; then come the places for pilot and observer. The pilot sits first, and the body of the machine is so high that only his head appears above it, while just in front of his face, to deflect the wind-rush from the propeller, there is a raised section of the hull which acts as a screen. Behind the pilot, sitting in a second opening in the hull, is the observer. He has a view forward, rendered the better by setting back the lower-plane; while at the point at which it joins the body of the machine, immediately below him, this plane is hollowed out, so that he can look directly upon the earth below. Small windows are also fitted upon either side of the hull. Through those in front the pilot may glance when descending from a flight, so as to judge his distance from the ground, while the others are utilised by the observer, as he turns to look from side to side. This biplane, and many others, is balanced against sideway roll by ailerons, and not by warping the wings. Constant warping, such as is necessary in the everyday use of machines, has been declared to strain a plane and render it weak; therefore the use of ailerons is now favoured. A. Propeller B.

A. Lower part of aeroplane’s hull B. Revolving barrel to which bombs are clipped C. Bombs D. Releasing mechanism operated by marksman in machine. Bombs may be carried and dropped when opportunity offers; and as an improvement upon the early method, which was simply to throw these from the machine, there are releasing mechanisms now devised which carry a number of projectiles and drop them one by one as a lever is moved. The bombs, which are long, pointed, and balanced so that they will fall head first, are clipped round a barrel rather like that of a revolver, which is fixed beneath the aeroplane’s hull just below the occupants’ seat. Mechanism causes the carrying chamber to revolve and bring each bomb against a releasing catch, which—at a movement of the marksman’s lever—throws it outwards and downward. - Manner of holding the Sling
In other instances we see it depicted with both the ends held in the hand, the figure being placed in the action of taking his aim, and a bird is generally the object of his exertion, as in the following engraving from a parchment roll in the Royal Library, containing a genealogical account of the kings of England, to the time of Henry III. - Sea-plane to carry a crew of seven
A coastal sea-plane, as now planned, is a craft having, say, two engines, each devolving 120 h.p., with a wing span of some 80 feet, and an accommodation in its hull for three men—the pilot, a combatant with a machine-gun, and an observer with an installation of wireless. But types are changing constantly, and the tendency is to build larger craft. A machine weighing a couple of tons is shown, and a novelty in regard to it is that it has wheels upon either side of its boat-shaped car, upon which it can move on land, and which fold upward when it rests upon the water.

Already, anticipating war in the air, a fighting aeroplane has been evolved; and a machine of this type is shown in Figure. The body, in which pilot and gunner sit, is armoured lightly with plates which will resist the penetration of a bullet. Such armouring was found necessary after the use of aeroplanes in Tripoli and the Balkans. When flying unavoidably low in these campaigns, and when fired at from the ground, the wooden bodies of machines were pierced by shot, and in several instances their occupants wounded.

Bullet Mold - Saxon Bow and Arrow.—X. Century
This engraving is made from a manuscript of the tenth century in the Cotton Library. The bow is curiously ornamented having the head and tail of a serpent carved at the ends; and was, probably, such a one as was used by the nobility. In all these bows we may observe one thing remarkable, that is, the string not being made fast to the extremities, but permitted to play at some distance from them. How far this might be more or less advantageous than the present method, I shall not presume to determine. - Slings of Warfare
Sometimes the sling is attached to a staff or truncheon, about three or four feet in length, wielded with both hands, and charged with a stone of no small magnitude. Those slings appear to have been chiefly used in besieging of cities, and on board of ships in engagements by sea. The following engraving represents a sling of this kind, from a drawing supposed to have been made by Matthew Paris, in a MS. at Bennet College, Cambridge. - Swords

From the Museum of Mitau in Courland - Aeroplanes attacking an airship from above
Airships, like aeroplanes, are being armed with guns and bombs; and their power of raising weights enables them to carry heavy weapons. Large and highly destructive bombs have been tested in the German airships, being released over the sea and aimed at targets in the form of rafts. Latest-type airships also carry guns in their cars; and the Zeppelins have a platform upon the tops of their hulls, reached by a ladder through the middle of the ship, from which a machine-gun can be fired upward. This is a very necessary precaution, and is intended to frustrate the attack of an aeroplane. It would be the aim of the latter, whenever possible, to manœuvre above its big enemy—as suggested in figure —and drop a bomb upon its hull. Hence the construction of the top platform of the airship, from which her gunners can direct a vigorous fire aloft. - Swords
