OCIOBKR 29, 1915. set of instruments, including engine revolution counter air speed indicator (Pitot tube), altimeter, inclinometer' hand-operated pressure pump, pressure gauge for the petrol, and a clock. For purposes of transport the main planes are made up in six sections as follows :—Two upper plane exten sions, two top planes, and two lower planes. They are built up of ribs over I-section spruce spars, the whole 1/jjGHU stabiliser is hinged a divided elevator, operated in the usual manner through cables running from the control lever to short crank levers on the elevator. At present the engine fitted is a 90 h.p. Austro-Daimler, which is supported on two engine bearers of ash, resting on four streamline ash struts that are secured at their lower extremities to the gunwales of the hull. In order to provide the necessary rigidity, and to take the stresses Three-quarter rear view of the new Thonus flying boat. being covered with high-grade Irish linen, and " doped " with seven coats of Emaillite. In order to preserve the dope and to make the fabric absolutely water and moisture proof, a coat of varnish is finally applied, giving a highly glossy finish to the wing covering. Two pairs of streamline spruce struts on each side connect the main planes, cross bracing being effected by means of stranded cables manufactured by Roebling. set up by the momentum of the engine when alighting two spruce struts are placed diagonally, running from the rear of the engine beaters to a point on the gunwales slightly ahead of the place where are attached the main front engine struts. Great attention has, as we have already pointed out, been paid to the general finish of this machine. All internal wooden parts are treated with a waterproofing Front portion of the hull and engine mounting on the new Thomas flying boat. The tail planes are of the usual form. A vertical rudder is pivoted round an extension of the stern post of the boat, and to balance the side area in front, presented by the flat sides of the hull, a large vertical fin is fitted, running forward from the rudder post to a point slightly more than half way between the stern and the rear cockpit. The horizontal stabilising plane is of semi circular plan form, and is carried on stanchions running up from the deck of the rear part of the hull. To t solution, while external parts of wood, such as struts and hull, are finished in natural wood. All metal parts are made rust proof by painting them with an anti-corrosive composition. The chief characteristics of the new Thomas flying boat are : Span of top plane, 39 ft.; span of lower plane, 28 ft. ; chord, 5 ft.; gap, 6 ft.; over all length, 28 ft. 6 ins. ; area, 360 sq. ft.; loading, 4*3 lbs. per sq. ft.; weight empty, 1,250 lbs.; speed, 65 to 70 m.p.h. 825
