prestige of “His Majesty's Service,” and it maintained all the old traditions of speed and punctuality—so much so that the villagers on the route set their clocks when the mail passed. The coming of the motor brought about another revolution. Many of my readers will remember the 14th November 1896, when a large number of motor carriages and vans assembled at Northumberland Avenue, Charing Cross, to celebrate by a run to Brighton the passing of the Act of Parliament which regulated the use of these vehicles. The Act came into operation on that day. Many of these motors never reached Brighton; they broke down at various points on the route; but the trip was an object-lesson to the British public of the possibilities of motor traffic. It impressed the Post Office authorities, who were among the first of the large business concerns in this country to adopt motor traction. As early as 1897 experimental trials were made between the General Post Office and the South-Western District Office, and between the latter office and Kingston-on-Thames. During the same year a steam motor was tried between London and Redhill, a distance of about 46 miles there and back. Experiments were also made with electric motors in different parts of the country at the same time. There was a difficulty at the outset owing to the Board of Trade regulations which prohibited vans weighing more than 1½ tons (unladen) from travelling more than 8 miles an hour. Difficulty was experienced in constructing cars of sufficient carrying capacity which should be within the limit of weight. This restriction was afterwards removed, so that it has been possible to build much larger motors, timed to travel at a faster rate of speed. In spite, however, of the numerous improvements in the mechanism of motors, the new method of traction was far from perfect for several years, and as late as 1902 the official report was, “So far no motor vehicle which has been found can be relied on to carry heavy mails with the same regularity as vans drawn by horses.” Even two years later, in 1904, the opinion held was “that motor vans were not so reliable as horse-drawn vehicles.” It is obvious that what the Post Office required was regularity and certainty rather than speed for their parcels traffic, and so long as the motor was constantly liable to breakdowns and maintained uncertain speeds it was unsuitable.
