However, transportation and travel continued to improve. On the main roads “waggons” were employed to transport goods and stage coaches for people, while pack animals and riding horses were used on less frequented trails and roads. Four and six horses were necessary to pull a carriage or a coach “because with a smaller number there was great danger of sticking fast in the mire.” A diligence ran between London and Oxford in two days, but in 1669 it was announced that the “Flying Coach would perform the whole journey between sunrise and sunset.” The heads of the university after solemn deliberation gave consent and the experiment proved successful. The rival university at Cambridge, not to be outdone, set up a diligence to run from Cambridge to London in one day. Soon flying coaches were carrying passengers to other points. Posts were established for the change of horses and longer distances essayed. This mode of traveling was extolled by contemporaneous writers “as far superior to any similar vehicles ever known in the world.” It is not to be thought that these advances in rapid transportation were without objectors. According to Macaulay, It was vehemently argued that this mode of conveyance would be fatal to the breed of horses and to the noble art of horsemanship; that the Thames, which had long been an important nursery of seamen, would cease to be the chief thoroughfare from London up to Windsor and down to Gravesend; that saddlers and spurriers would be ruined by hundreds; that numerous inns, at which mounted travelers had been in the habit of stopping, would be deserted, and would no longer pay any rent; that the new carriages were too hot in summer and too cold in winter; that the passengers were grievously annoyed by invalids and crying children; that the coach sometimes reached the inn so late that it was impossible to get supper, and sometimes started so early that it was impossible to get breakfast. Objections of this character have been made against every innovation and advancement in travel and transportation to the present day when the air-plane is beginning to attract notice as an economic vehicle. Laws were then demanded and passed, as they are now, to regulate power and speed, accommodations and rates, and multifarious other things which might affect the privileges or profits of those interested in older methods, as well as laws for the protection and safety of the general public.
