THE Leyland exhibit is most attractive, both in appearance and in the products displayed, of which, in our opinion, the most striking is the new six-cylinder Titan double-deck bus with enclosed top. The chassis of this vehicle is of an entirely new design, and the same applies to the body, which is of a patent type giving ample headroom in both saloons and yet permitting an overall height, when loaded, of under 13 ft., and it is owing chiefly to this feature that the vehicle on view is one purchased by the city of Lincoln, as no other covered-top bus could pass under the famous Stonebow. It is most attractively finished in the city's colours of grey and pale yellow. The secret of this la* construction, apart , from the, design of the chassis, is the stepped floor of the upper deck which gives a gangway projeCting into the lower Part of the vehicle, but as this comes immediately above the seat at the off side it does not interfere with the comfort of the passengers.

Nextin interest is a remarkably well-finished and equipped single-deck bus built for H. 3./. S. Catherwood, the wellknown Irish user. It is a 32-seater with a rear entrance, and at the right of this entrance, occuping approximately half thewidth of the vehicle at the back, is a luggage rack with several tiers, whilst further accommodation for luggage is provided on the railed roof at the back.

The chassis employed closely resembles that used for the Titan. It has an overhead-valve six-eylindered engine of 4-in, bore and 5i-in. stroke, giving a maximum b.h.p. of 100. The cylinders are cast en bloc, and it has a detachable head in one piece, whilst an aluminium cover is mounted over the valve rockers which are operated by an overhead camshaft driven through the medium of a duplex roller chain and a pair of wide skew gears. To take up any slack in the timing chain there is a spring-tensioned • sprocket. Another interesting situated at the off side, a small port from each communicating with the combustion chamber at a point close to the centre. The engine is offset and is set at an angle to the centre line of the chassis so as to give a straight-line drive to the underneath worm of the rear axle, the pot of which is well over to the near side. A centre bearing la, of course, employed for the two-piece propeller shaft. A single-plate, .fabricto-metal clutch takes the drive to a four. speed gearbox which is spigoted into a special, cross-member constituting the rear suspension of the engine-gearbox

unit thus formed.

The braking is excellent, there being

four pairs of shoes in the rear-wh drums and two pairs in the frc wheels. A pedal operates the brakes all four wheels through a Dewan( servo; a hand lever controls the oti set of shoes in the rear wheels. Drui 17 ins, in diameter are employed a the vehicle runs on 38-in. by 8/low-pressure tyres With' twins at, t rear. ,

The third passenger vehicle is a lo Lion 32-seater single-deck bus with f( 'ward control, a folding front entran door, emergency exit and semi-buck seats.

As regards goods vehicles, there is 4-ton Gla2 chassis equipped with special box-van body for the Bank England. This is a type suitable fo high-speed work and runs on 38-in. b 7-in, pneumatic tyres.

FinallY, there is a neat 7-cwt. Trojai van, the examples shown being the lon model with cantilever front springs, bu semi-elliptic springs at the rear. Th well-known Trojan two-stroke four cylinder engines are, of course, em ployed in these useful light carriers.
