The growing popularity of the cabs soon thoroughly alarmed the hackney-coachmen, who at first had jeered at the new vehicle and prophesied a short career for it. They endeavoured to get their licence-plates transferred to cabs, but were unsuccessful, for the cab proprietors of that period were men of good social position--some of them occupying Government appointments--and all the influence which they could command was exerted to keep the trade in their own hands. In spite of the protests of the hackney-coach proprietors this monopoly existed for nearly ten years, and many of the aristocratic cab owners amassed money rapidly. They did not believe in having a large number of cabs, even of their own, on the streets, and for some months there were only fifty. Afterwards the number was raised to one hundred, and in 1831, to one hundred and fifty. In Paris in the same year, there were nearly two thousand five hundred of them! In 1832, when the number of London cabs reached one hundred and sixty-five, the disgraceful monopoly was put an end to, and, all restrictions being removed, hackney-coach proprietors were at last enabled to transfer their licences from their coaches to cabs. In a few weeks there were several hundred cabs, and other two-wheel vehicles, plying for hire in the streets. A paper called _The Cab_ was started immediately, but the title was chosen simply to attract attention, as, although the publication bore on the front page a small and blurred illustration of a cab, its contents were literary odds and ends. In the “Answers to Correspondents” column, a cabman’s MS. was declined with thanks. Its non-publication is to be regretted. Some months later a new cab, invented and patented by Mr. William Boulnois, father of Mr. Edmund Boulnois, M.P., was placed on the streets. It was a two-wheeled closed vehicle, constructed to carry two passengers sitting face to face. The driver sat on a small and particularly unsafe seat on the top of it, and the door was at the back. It was, in fact, so much like the front of an omnibus that it was well known as “the omnibus slice.” Its popular name was “the back-door cab.” Superior people called it a “minibus.” This cab was quickly followed by a very similar, although larger, vehicle invented by Mr. Harvey. It was called a “duobus,” a name frequently applied to Mr. Boulnois’s cab. A young man of good family, who had squandered a fortune, conceived the idea of earning his living by driving a back-door cab of his own. His friends having supplied him with the necessary capital, he created a sensation by appearing one morning in the Haymarket driving a superbly fitted and splendidly horsed cab. The result of his first morning’s work was very satisfactory, and the young cabman was in high spirits. But driving to the stables, his horse stumbled and fell, and, taken by surprise, the unfortunate young cabman was pitched head-first into the road, and killed on the spot.
