It made several sharp turnings round corners, the radius of the path of travel being not more than 15 ft. With one ordinary iron skid on the rear wheel of the hindmost lorrie, it desended Rome-lane--a steep falling grade--under complete control. The rough and irregular stone causeway, the timber bridleway of the Chatham Dockyard, and the rough and broken ground near the landing quay on the Medway were all smoothly and successfully traversed. The girders were landed on the quay, and the engine then returned to Rochester. The ground near the landing quay is full of hillocks of cinder, clinker, stone, bricks, scrap iron, &c, but, although the engine ran over all these substances, not a cut nor permanent indent was to be found afterwards in the india-rubber segments. The great advantage of Messrs. Sterne's method of attaching the india-rubber in segments over the solid ring is, that if a segment gets damaged it is easily and quickly removed and replaced by a spare segment at a moderate cost. The motion of the engine during the run was easy, and the india-rubber readily impressed itself into the inequalities of the roadways. To avoid all possibility of slip in wet streets and on clay soils, Mr. Aveling proposes to introduce steel staples or crossbars, so arranged as to take the traction without neutralising the benelit derived from the elastic action of the rubber.
