Without adopting Mr Bourn's 16-inch cast-iron garden rollers, the carriers of the period did, apparently, adopt the 9-inch wheels favoured by Parliament; but as they found that, with 9-inch wheels, they could carry much heavier weights, there had to be a further resort to legislation directed to a limitation of loads. This was done by 5 Geo. III., c. 38,[[7]] while under 6 Geo. III., c. 43, turnpike trustees were directed to issue orders to their collectors not to allow any waggon or other four-wheeled carriage having wheels of less than 9 inches in breadth to pass through a toll-gate when drawn by more than four horses without seizing one of the horses. By 13 Geo. III., c. 84, the reduced tolls already conceded to 9-inch wheels were extended to 6-inch wheels, and it was further provided that waggons with 16-inch wheels should pass toll free for a year, and then pay only one-half of the tolls to be paid by 6-inch wheeled waggons.
In order to give still further encouragement to the use of 16-inch wheels, an Act passed in the following year provided that any waggon having wheels of those dimensions should pass toll-free for five years instead of one, and pay only half toll afterwards.
Among the many other Acts that followed, mention may be made of 55 Geo. III., c. 119, which gives an especially good idea of the infinite pains taken by the Legislature to adapt the construction of vehicles to the apparently hopeless deficiencies of the roads. The Act authorised road trustees to exempt certain vehicles from tolls for overweight "provided such Waggon, Cart or other such Carriage shall have the Soles or Bottoms of the Fellies of all the Wheels thereof of the Breadth of Six inches, or of Nine Inches, or of Sixteen Inches or upwards, and be cylindrical, that is to say, of the same Diameter on the Inside next the Carriage as on the outside, so that when such Wheels shall be rolling on a flat or level Surface, the whole Breadth thereof shall bear equally on such flat or level Surface; and provided that the opposite Ends of the Axletrees of such Waggon, Cart or other Carriage, so far as the same shall be inserted in the respective Naves of the Wheels thereof, shall be horizontal and in the continuance of one straight Line, without forming any Angle with each other; and so that in each pair of Wheels belonging to such Carriage, the lower Parts, when resting on the Ground, shall be at the same distance from each other as the upper Parts of such Pair of Wheels: Provided always," etc.
Under 3 Geo. IV., c. 126 (1822) no waggon or cart with wheels of less breadth than 3 in. was to be used on any turnpike road from the 1st of January, 1826, under a penalty of not exceeding £5 for the owner and not exceeding forty shillings for the driver; but this provision was repealed by 4 Geo. IV., c. 95 (1823), "in compliance," says Dehany, "with a cry raised on the part of the farmers and agriculturists, who, in petitions and complaints against the Act, put forward this clause as a principal grievance."
The broad-wheel policy of successive Governments evoked a good deal of criticism from others besides farmers and agriculturists, who themselves seem to have been reduced from time to time by the ever-changing regulations and restrictions to a condition almost of despair. In speaking of the roads in the parish of Eccles, Dr Aikin, writing in 1795, says in his "Description of the Country from Thirty to Forty Miles round Manchester" that although "much labour and a very great expense of money" had been expended on them, they still remained in a very indifferent state owing to the immoderate weights drawn in waggons and carts, and he adds: "To prevent this, vain and useless are all the regulations of weighing machines; and the encouragement of broad and rolling wheels still increases the evil, which must soon destroy all the best roads of Great Britain."
The general effect of the legislation in question was, also, thus commented on by William Jessop in an article on "Inland Navigation and Public Roads," published in vol. vi. of the "Georgical Essays" (1804):—
"I do not know anything in this country ... that has been more neglected than the proper construction of wheel carriages and the formation of roads. It has been generally acknowledged that for carriages of burden broad wheels, which will roll the roads, are the most eligible; and by the exemptions which have been granted to those who use broad wheels, the legislature has certainly looked forward to the benefits to be expected from the use of them; but never was a proposition more misunderstood, or an indulgence more abused. Of all the barbarous and abominable machines that have been contrived by ignorance, and maintained by vulgar prejudice, none have equalled the broad-wheeled carriages that are now in use; instead of rolling the roads, they grind them into mud and dust."
Not alone cart-wheels, but even cart-wheel nails, engaged the serious attention of Parliament, and formed the subject of special legislation. The Act 18 Geo. II., c. 33, provided, among other things, that the streaks or tires of wheels were to be fastened with flat, and not rose-headed, nails; and an Act passed in 1822, in the reign of George IV., directed that when the nails of the tire projected more than a quarter of an inch from the surface of the tire the owner of the waggon should pay a penalty of £5 and the driver one of forty shillings for every time such vehicle was drawn on a turnpike road; though an amending Act, passed the following year, reduced the penalties to "any sum not exceeding" forty shillings for the owner and twenty shillings for the driver.
Towards the end of the long period here in question it began to be realised that what was wanted, after all, was an adaptation of the roads to the traffic rather than an adaptation of the traffic to the roads; but the change in policy was not definitely effected until two practical-minded men, John Loudon McAdam and Thomas Telford, had introduced, at the beginning of the nineteenth century, the first attempt at really scientific road-making which had been made in this country since the departure of the Roman legions in the early part of the fifth century.
