The experiment took place “abreast between the new road just by Pancras to within a small distance of Bog-house Bar.” Apparently the only advantage which the new waggon possessed was its ability to turn in a narrow road, but although Mr. Bourn not only continued to build such waggons, but also answered his opponents in two tracts, we hear little more of him. Such “rolling-carts,” however, were also made by one James Sharpe, of Leadenhall Street. Sharpe was a pushful man. He believed in his system, and apparently made those in authority see its advantages. His rollers, you learn, were cylinders of cast iron, two feet in diameter and sixteen inches broad. An iron spindle was inserted through the centre of each. Several of Sharpe’s waggons were on the roads, but although every facility was given them, they never really took the popular fancy. And indeed, they must have been uncouth monsters rattling along the roads something after the fashion of the steam-roller of ten years ago. Just about this time, too, the light-cart faction showed that it was not in the least moribund. It indited learned and highly technical articles which the newspapers found space to print with some regularity. A typical reply to such articles was inserted in the _Public Advertiser_ early in 1767:— “There are people, I may say,” runs this most impolite retort, “a depraved Number, who write long letters upon this Subject in an ignorant Manner. Their Errors confirm Mankind of a sensible Turn what Measures ought to be taken for the Benefit of the trading Part of this Nation. The illiterate Scribblers he [the last correspondent] means to lash are those that insist upon the Necessity of Horses going at length instead of being placed abreast. The Power that draft Horses have in being placed abreast is so well known, that ’tis amazing any body is absurd enough to advance a Doctrine to the contrary. Then again, these deluded Idiots propagate, that the Loads drawn by eight Horses, having the Wheels placed nine Inches within nine, are destructive to the Roads, and that the Weight had better be divided into several narrow wheeled Carriages. Being thus destitute of Judgment upon the Subject, they do not reflect that the more Horses and Carriages the more the Expence increases, consequently that the internal Trade of this Kingdom would advance in this Article 100 per Cent. One Waggon with eight Horses in Pairs, drawing eight Ton upon the new Plan, don’t do near the Mischief that the same Weight would in two Waggons with narrow Wheels. Besides, four Horses at length cannot draw four Ton Weight. A late trifling Writer upon the Subject says, the Appearance of a broad Wheel Waggon was terrific. I think he may be pronounced a Cockney without Ceremony—a Cit that carries his Wife and Children four Miles out of Town in a Tim-Whisky, and, being most likely an aukward
