Dance ran Gurney's coaches on the Cheltenham and Gloucester Road until public opposition compelled his withdrawal, but after that he was a joint patentee with Joshua Field, of an improved boiler. This was applied to the road carriage above mentioned and the first trips were made in September, 1833, with a drag and omnibus attached, a speed of sixteen miles an hour being attained. On the first trip from London to Brighton, fifteen passengers were carried and the distance of fifty-two miles was covered in five and a half hours, the return journey being performed in less than five hours. About the middle of October the steam drag and omnibus were put upon the road between Wellington Street, Waterloo Bridge, and Greenwich, where it continued to run for a fortnight, with a view of showing the public in London what could be done in this direction. The proprietor had no intention of making it a permanent mode of conveyance, and therefore kept the company as select as he could by charging half a crown for tickets each way. JOSHUA FIELD Born in 1786. Died in 1863. A member of the well-known firm of Maudsley, Sons & Field, marine engineers, of London, England, Joshua Field took out a patent for an improved boiler, in conjunction with Sir Charles Dance. The firm made an improved vehicle for Dance, and in 1835 Field constructed for himself a steam carriage that made a trip in July with a party of guests. The carriage was driven up Denmark Hill, and did the distance, nine miles, in forty-four minutes. It also ran several times to Reading and back, at the rate of twelve miles an hour. One of the subscribers towards the building of this carriage, said that it was a success mechanically, but not economical. Field was one of the six founders of the Institution of Civil Engineers. DIETZ Previous to the time that the carriage of Francis Maceroni was taken to France, an engine designed by Dietz was run in the streets of Paris. In the reports of the Academy of Sciences and Academy of Industry in Paris, in 1840, this vehicle was described. The carriage had eight wheels, two of which were large and gave the impulsion. The six smaller wheels rose and fell according to the irregularity of the road, and at the same time assisted in bearing the weight of the carriages. The wheels were bound with wood tires, having cork underneath. The locomotive was a drag, drawing a carriage for passengers. The engine was of thirty horse-power, and a speed of ten miles an hour was made. YATES A steam carriage was built by Messrs. Yates & Smith, London, in 1834. It had a trial in July of that year, running from the factory in Whitechapel, along High and several other streets, at the rate of ten to twelve miles an hour. Vibrating engines, working on horizontal framing, were used. The coach resembled an ordinary stage-coach. G. MILLICHAP
