Before Macadam and Telford appeared upon the scene, the office of road-surveyor was very generally looked down upon. No self-respecting engineer, before the time of these great men, condescended to have anything to do with roads. It is true that a forerunner of Macadam and Telford had appeared in Yorkshire in 1765, when “Blind Jack of Knaresborough” began the construction of the Boroughbridge and Harrogate road, the first of the long series for which he contracted; but he was not an official road-surveyor, nor by profession an engineer. He was, in fact, an engineer born and wholly untaught.

John Metcalf, the famous blind roadmaker, was born in 1717, and lost his eyesight at six years of age. A native of Knaresborough, he filled in his time many parts; being fiddler, huckster, soldier, carrier, proprietor of the first stage-wagon between York and Knaresborough, and road and bridge maker and contractor by turns. The marvellous instinct which served him instead of sight is scarce credible, but is well authenticated. He joined Thornton’s company of Yorkshire volunteers raised at Boroughbridge to meet the Scots rebels in the ’45, and marched with them and played them into action at Falkirk. His marvellous adventures have no place here, but his solitary walk from London to Harrogate in 1741 concerns the Great North Road. Being in London, and returning at the same time, Colonel Liddell of Harrogate offered Blind Jack a seat behind his carriage, which Metcalf declined, saying that he could easily walk as far in a day as the colonel could go in his carriage with post-horses. This incidentally shows us how utterly vile the roads were at the time. Metcalf, although blind and unused to the road, having travelled up to London by sea, walked back, and easily reached Harrogate before the colonel, who posted all the way.

Liddell, who had an escort of sixteen mounted servants, started an hour later than Metcalf. It had been arranged that they should meet that night at Welwyn, but, a little beyond Barnet, on Hadley Green, where the roads divide, Metcalf took the left hand, or Holyhead, road by mistake and went a long distance before he discovered his mistake. Still he arrived at Welwyn first. The next day he was balked at Biggleswade by the river, which was in flood, and with no bridge to cross by. Fortunately, after wandering some distance along the banks, he met a stranger who led the way across a plank bridge. When they had crossed, Metcalf offered him some pence for a glass of beer, which his guide declined, saying he was welcome. Metcalf, however, pressed it upon him.

“Pray, can you see very well?” asked the stranger.

“Not very well,” replied Blind Jack.

“God forbid I should tithe you,” said his guide. “I am the rector of this parish; so God bless you, and I wish you a good journey.”

In the end, Metcalf reached Harrogate two days before the colonel.

Metcalf made many roads around Knaresborough and in different parts of Yorkshire, but none actually on the Great North Road. He died, aged ninety-three, in 1810, five years before Macadam and Telford began their work upon the roads. Like them, he rather preferred boggy ground for road-making, and forestalled both them and Stephenson in adopting fagots as foundations over mires. At that time the ignorant surveyors of roads repaired them with dirt scraped from ditches and water-courses, in which they embedded the first cartloads of stones which came to hand; stone of all kinds and all sizes. This done, their “repairs” were completed, with the result that the roads were frequently as bad as ever and constantly in the most rugged condition. Roads—it may be news to the uninstructed—cannot be made with dirt. In fact, a good road through anything but rock is generally excavated, and the native earth being removed, its place is taken by coarse-broken granite or rock; this in its turn receiving a layer of “macadam,” or smaller broken granite or whinstone, which is finally bound together by a sprinkling of red gravel, of the kind known by builders as “hoggin,” whose binding qualities are caused by a slight natural admixture of clay. In his insistence upon broken stones, Macadam proved a power of observation not possessed by the generality of road-makers, whose method was the haphazard one of strewing any kind upon the road and trusting in the traffic to pack them. With rounded pebbles or gravel stones thus chafing against one another, they never packed into a solid mass, but remained for all time as unstable as a shingly beach. Generations of road-making had not taught wisdom, but Macadam perceived the readiness of the angularities in broken stones to unite and form a homogeneous mass, and in introducing his system proved himself unwittingly a man of science, for science has in these later days discovered that ice is compacted by the action of ice-crystals uniting in exactly this manner.

A great scheme for laying out the whole of the Great North Road between London and Edinburgh on a scientific basis was in progress when the successful trial of the competing locomotives at Rainhill, near Liverpool, cast a warning shadow over the arrangements, and finally led to the project being entirely abandoned. Had the work been done, it is quite possible that the railways to the north would have taken another direction; that, in fact, instead of land having to be surveyed and purchased for them, the new, straight, and level road would have been given up to and largely used by the railways. Telford was the engineer chosen by the Government to execute this work, of which the portion between Morpeth and Edinburgh was actually constructed. The survey of the road between London, York, and Morpeth was begun as early as 1825, and had been not only completed, but the works on the eve of being started, when the Rainhill trials in 1829 stopped them short, and caused the utter waste of the public money spent in the surveying.
