AUGUST 12, 19/0 screened extra air ports, simultaneously with its opening to the said induction bar, both throttles, of course, being interconnected to the spindle of a quadrant which is mounted upon the bronze T-union of the two water circulation inlet branches that run along the inside of the V and the main lead from the pump below. As to the- timing and distribution gear, the cam-shaft spur-wheel has a rearward bevel-face, engaging a horizontal bevel gear driving a vertical spindle. This spindle in the first place carries a helical gear-drive for the transverse spindle drive of the two platformed magnetos, then a bevel drive below that to the spur-type water-pump; and below again—where it emerges from the gear casing and is contained in a tube, bracket-attached to the crank-chamber—it drives a small spur-type oil-pump, which draws by outside piping from a deep air-cooled base-chamber, and returns the oil by distribution piping to the bearings, thence force- feeding throughout by leads in the crank-shaft and connecting rods to all interior surfaces. The 250 h.p. six-cylinder S.P.A. appears to bear out all the reputation of its makers as a thoroughly sound job. But its " design, so far from representing any such advance as is seen inrsome of the latest Italian models, appears to belong to the style of 1917-18 rather than anything later, and thus to take after the German practice of that time. Thus one sees the cylinders cast in pairs, with tripartite induction from two Zenith carburettors, and welded steel water-jackets, a detail which is only one of many in which this motor has been so cleverly lightened without reducing its strength, so that it only weighs 1 kilo per h.p. The valves are set diagonally in the head at about 10 degrees and actuated by rockers of bell- crank angle, neatly half-concealed within the tubular casing of the overhead cam-shaft, to which the oil is fed and returned by way of the copper-pipes at the front end, rising out of the crank-chamber from the distribution system within. The vertical drive-shaft, through two bevels of a train of four, drives transverse magneto spindles, behind which the fourth bevel drives a centrifugal water pump, while the oil-pump —which is also of_the centrifugal type—is driven direct from the crank-shaft end at engine speed, and through outside connections, draws from leads inside the base chamber direct from- the central sump, and delivers the oil to all bearings. . - (To be Continued) • • ' Deaths 7.

Their Majesties Inspect Seaplane Works ON Sunday afternoon, the King and Queen, Princess11 Mary and the Duke of York, attended by the Marquise D'Hautpoul, Sir Charles Cust and Admiral the Hon. Sir Hubert Brand, visited the seaplane, motor-boat and motor- car works of Messrs. Saunders and Co. They were received by Mr. S. Saunders, the head of the firm, and his son Mr. Herbert S. Saunders, and first visited the aircraft sheds, where they inspected the " Kittiwake," the Saunders amphibian, built for the Air Ministry Trials, and entirely constructed on the " Consuta" system of plywood sewn together. Motor-car bodies made in the same way were also seen, and then, motoring to the Cornubia yard, the two racing motor-boats, " Maple Leaf V " and " Maple Leaf VI," built for Sir Mackay Edgar to defend the British International Trophy in this week's race, were inspected. Their Majesties were shown several motor-boats, which are being built in large numbers for British and foreign customers, and also inspected two large Valencia armed flying boats, building for the Air Ministry. Each has a capacity of about 9 tons, and carries a shell-throwing gun. The King and Queen expressed their sincere thanks to Mr. Saunders, saying how deeply interested they had been iu all they saw. Cancelling Flax Control THE Minister of Munitions has issued an order, to be uted the Flax Control (Cancellation) Order, 1920, by which tlie following are cancelled :— Flax (Irish Crop) Order, 1917 ; Spun (Flax) Yarn Order,x 0i7 ; Flax (Irish Crop) Order, 1918 ; Rescutched Tow (•rder, 1918 ; Rescutched Tow No. 2 Order, 1918 ; Flax (Irish Crop) Order, 1919 ; and Flax (Irish Crop) Amendment -Vo. 2 Order, 1919.

A Scottish Aerial Derby A PROPOSAL is on foot to organise a race on Aerial Derby lines over a 100 miles' course, taking in Edinburgh, Glasgow and Stirling. The route proposed is a triangular one, from Turnhouse aerodrome, circling the flying ground at Renfrew, then round Stirling and back to Turnhouse. It is anticipated that there will be a good entry and further details will be awaited with interest. By Aeroplane to see the Prince -•-.-- HOPING to catch a fleeting glance of the Prince of Wales . before his departure southwards, Mr. Fihelly, ex-Premier of Queensland, arranged to travel by aeroplane to the border. He left Brisbane at 9 o'clock in the morning, but a forced descent at Warwick, two-thirds of the way, caused him to miss the train. He flew into New South Wales with the hope of picking up the Prince at the first stopping-station, but was too late. R.A.F. Memorial at Walmer - A MEMORIAL erected at Walmer Aerodrome by Lady Beauchamp to fifteen officers of the Royal Air Force who served at the aerodrome and lost their lives in the War was unveiled on August 7 by Air Commodore C. L. Lambe, C.M.G., D.S.O., and dedicated by the Chaplain-in-Chief of the Royal Air Force. A letter was read from the Duke of York expressing sympathy with the relatives " of the gallant men who gave their lives for their country and Empire' in the service to which I have the honour to belong."
