It was an eight-wheeled engine, and the driving-wheels were eight feet in diameter. The cylinder was eighteen inches, with a piston of two feet stroke, and the total weight of engine and tender was fifty-three tons. The cost of this iron horse with its tender was about 3000 pounds.

As the dust began to settle it was possible to observe that attached to the locomotive was a square, solid, wooden van, the movable residence of the stoker, the engineer, and an apprentice; that a Powler cultivator, a fearsome piece of mechanism, apparently composed of second-hand anchors, chain-cables, and motor driving-wheels, was coupled to the back of the van, and that a bright green water-cart brought up the rear.

On the crank, F, is secured an eccentric, that works within the slot of the slotted lever, o squared, during the revolution of the crank, F, and in this manner imparts the requisite motion to the slide valve, o, to admit the steam into the cylinder, g, alternately between the pistons, k and k', and at the ends of said cylinder, g, so as to alternately force the pistons, k and k', from and toward each other, and thus, in combination with the vibratory motion of the truss, i, impart a rotary motion to the driving-wheels, e and f.

Ford's works at Trafford Park, Manchester, where one of the motors had been sent to be dismantled and inspected in detail. We find the design of ample strength, and the work of first-rate quality. We consider the driving-wheels rather light, and we understand that a new and stronger pattern is to be supplied in future.

The big ten-wheeler coughed hoarsely and spat fire; the driving-wheels made a quick half-turn backward; and a cheer from the onlookers marked the little triumph of mind over matter. Winton found Miss Carteret holding his overcoat when he swung down from the cab, and he fancied her enthusiasm was tempered with something remotely like embarrassment.

The automobile builders have a problem that troubles locomotive builders very little that is, compensating the difference between the speeds of the two driving-wheels when turning corners.

This hand-wheel was located in the cab, where it was easily accessible.... "The rough outline sketched below shows the location of motor in relation to counter-shaft, belting, driving-wheels, idler, etc.: "On account of both rails being used for circuits, . . . the driving-wheels had to be split circumferentially and completely insulated from the axles.

It has great strength and resistance, owing to the fact that no pressure is exerted on the journals on which the steam cylinders oscillate, and all the pressure from the steam pistons is directly transferred to the crank-pins on the driving-wheels.
