JULY 27, 1916. bracing wires. The fitting is quickly and cheaply made, being, as already mentioned, of very light gauge, and by making it in two standard sizes it can be em ployed irrespective of the taper of the body rails. In front a number of the metal fittings take the form of large Duralumin plates serving a variety of purposes. * Flight " Copyright. One of the strut sockets of the L. and P. biplane. " Several of these plates can be seen in the illustrations. A turtle back, consisting in front of three-ply wood, and at the rear of formers and stringers, tops the body and helps to give the necessary depth for effec tively enclosing the occupants, of whom nothing but the heads are seen when the machine is flying. The pilot occupies the back seat, and lias in front of him a neatly fitted dashboard with all the usual instru ments, including engine revolution counter, altimeter, "Flight" Copyright.

In front of the pilot, and in a separate cockpit, is installed the passenger, whose seat is placed on top of the main petrol tank, which in turn rests on the bottom of the body. From this tank^the fuel is forced by means of a pressure pump to a smaller service tank in the nose of the body. The controls consist of a central lever of wood 62 (/)JGHT) mounted on a longitudinal rocking shaft, and of a foot bar for the rudder. The engine—an 80 h.p. Anzani—is mounted in the usual manner on a capping plate bolted to the rails of the body. In order to further stiffen the mounting, two tubes are taken from the bolts of the crank-case " Flight" Copyright.

The main planes, which are of a section somewhat similar to the R.A.F. 6, with the exception that the lower surface is slightly more cambered, 1 \ in. to be exact, are characterised by heavily raked tips which tend to give the machine a " racy " appearance, and which perform the more useful function of decreasing end losses and increasing the effectiveness of the ailerons.
