In this carriage, the Earl of Caithness traveled from Inverness to his seat, Borrogill Castle, within a few miles of John o' Groat's House. He describes his trip as follows: "I may state that such a feat as going over the Ord of Caithness has never before been accomplished by steam, as I believe we rose one thousand feet in about five miles. The Ord is one of the largest and steepest hills in Scotland. The turns in the road are very sharp. All this I got over without trouble. There is, I am confident, no difficulty in driving a steam carriage on a common road. It is cheap, and on a level I got as much as nineteen miles an hour." The Earl of Caithness brought the trial to a successful result, and some expert authorities jumped to the conclusion that at once steam traveling upon the high roads of England would be availed of to a large extent; but that did not happen. In 1864, Mr. Rickett furnished an engine for working a passenger and light goods service in Spain, intended to carry thirty passengers up an incline of one in twelve, at ten miles an hour. The steam cylinders were eight inches in diameter, and the driving wheels four feet in diameter. The boiler would sustain a pressure of two hundred pounds. Rickett's later engines had spur wheels; but his last engines were direct-acting. In November, 1864, he says: "The direct-acting engines mount inclines of one in ten easily; whether at eight, four, two, or one mile an hour, on inclines with five tons behind them, they stick to their work better than geared engines." DANIEL ADAMSON In 1858 the firm of Daniel Adamson & Co., of Dukinfield, near Manchester, England, built a common-road locomotive for a Mr. Schmidt. A multi-tubular boiler was used, two and one-half feet in diameter and five and one-half feet long, with a working pressure of one hundred and fifty pounds per square inch. The engine, which weighed five thousand six hundred pounds and was borne on three wheels, was calculated to run at eight miles an hour. A steam cylinder of six-inch diameter was attached to each side of the locomotive, and these cylinders actuated a pair of driving wheels three feet six inches in diameter. Mr. Schmidt gave this vehicle a thorough trying out and especially raced it with several competitors. On one of these races, in 1867, with a Boulton steam carriage, the start was made from Ashton-under-Lyne, for the show ground at Old Trafford, a distance of over eight miles. Although the Adamson engine was the larger, the smaller one easily passed it during the first mile, and kept a good lead all the way, arriving at Old Trafford under the hour.
