In the same year (1755) in which the Bill for the construction of the Sankey Canal was obtained, the Corporation of Liverpool already had under consideration a scheme for a canal from the Mersey to the Trent; but no definite action was then taken, and it was left for private enterprise to carry out the idea. The chief promoters were Earl Gower (ancestor of the Duke of Sutherland), the Duke of Bridgewater, the Earl of Stamford, Josiah Wedgwood, and various other landowners and manufacturers. Parliamentary powers were obtained in 1766, and the work of construction, as planned by Brindley, was begun at once. The name of "Grand Trunk" was given to the undertaking, the idea being that the waterway would form the main line of a system of canals radiating from it in various directions, and linking up the greater part of the country south of the Trent with the three ports mentioned.

We have here the first suggestion of any approach to a real system of inland communication, as applying to the country in general, which had been attempted since the Romans made the last of their great roads in Britain. Apart from the natural limitations of navigable rivers, the turnpike roads so far constructed had been chiefly designed to serve local interests, and successive rulers or Governments had either failed to realise the importance of carrying out a well-planned scheme of inland communication, embracing a great part even if not the whole of the country, or had been lacking in the energy, or the means, to supply what had become one of the greatest of national wants.

There was thus all the more credit due to the little group of far-sighted, enterprising and patriotic individuals whose names I have mentioned that they should themselves have undertaken work which was to have an important influence on the industrial and social conditions of the country. Yet the nature of the conditions under which the Trent and the Mersey section of the Grand Trunk system was made afforded an early example of the physical difficulties attendant on canal construction in England which were to be a leading cause of the decline of canals as soon as the greater advantages of the railway and the locomotive had been established.

Canals were superior to rivers in so far as they could be taken where rivers did not go, and could be kept under control in regard to water supply without the drawbacks of floods or droughts, of high tides, or of being silted up by sand or mud. It is, indeed, reported that when, after he had made a strong pronouncement in favour of canals, James Brindley was asked by a Parliamentary Committee, "Then what do you think rivers are for?" he replied, "To supply canals with water."

On the other hand, water would not flow up-hill in canals any more than in rivers, and in the making and operation of canals there was, literally as well as figuratively, a great deal of up-hill work to do.

Between the Mersey and the Trent there were considerable elevations which formed very difficult country for water transport. These elevations had to be overcome by the gradual rising of the canal, by means of locks, to a certain height, by the construction, at that point, of a tunnel through the hills, and by a fresh series of locks on the other side, to allow of a lower level being reached again. The rise of the Trent and Mersey Canal from the Mersey to the summit at Harecastle, near the Staffordshire Potteries, was 395 ft., a final climb of 316 ft. being made by means of a flight of thirty-five locks. Through Harecastle Hill there was driven a tunnel a mile and two-thirds in length, with a height of 12 ft. and a breadth of 9 ft. 4 in.[[25]] South of this tunnel the canal descended to the level of the Trent, a fall of 288 ft., by means of forty locks. In addition to this the canal, in its course of 90 miles, had to pass through four other tunnels and be carried across the river Dove by an aqueduct of twenty-three arches and at four points over windings of the Trent, which it followed to its junction therewith at Wilden Ferry.

These engineering difficulties were successfully overcome by Brindley, and the canal was opened for traffic in 1777. The benefits it conferred on industry and commerce, having in view the unsatisfactory alternative means of transport, were beyond all question. English traders saw established across the island, from the Mersey to the Humber, a line of inland navigation which, apart from the long and tedious voyage round the coast, and, also, from the scarcely passable roads, was the first connecting link in our national history between the ports of Liverpool and Hull. But of even greater importance were the facilities for making use of either or both of these ports—the one on the west coast, and the other on the east coast—which were opened up to manufacturers and traders in the midland districts, and especially when the Trent and Mersey Canal was supplemented by the Wolverhampton (now the Staffordshire and Worcestershire) Canal, connecting the Trent with the Severn; the Birmingham Canal; the Coventry Canal (which gave through navigation from the Trent via Lichfield and Oxford, to the Thames); and others.

Of the many districts benefitted it was, perhaps, the Potteries that received the maximum of advantage. Fourteen years before the Trent and Mersey Canal was opened for traffic—that is to say, in 1763—Josiah Wedgwood perfected a series of improvements in the pottery industry which foreshadowed the probability of the manufacture of coarse pottery—already carried on in North Staffordshire for many years—developing into the production of wares of the highest excellence, for which a great market would assuredly be found not only throughout England but throughout the world. The one drawback to an otherwise very promising outlook lay in the defective communications. The roads were hopelessly bad and the navigable rivers were far distant. It was almost impossible to get sufficient clay for the purposes of raw material, and the cost and the risk of damage involved in long land journeys before the goods could be put on the water, for carriage to London or the Continent, almost closed those markets for the Staffordshire manufacturer.

In 1760—three years before Josiah Wedgwood started his new era in pottery manufacture—the number of workers engaged in the industry did not exceed 7000 persons; and not only were they badly paid and irregularly employed but in their position of almost complete isolation from the rest of humanity they were, as Smiles puts it in his "Life of James Brindley," "almost as rough as their roads." They were ill-clad, ill-fed and wholly uneducated; they lived in dwellings that were little better than mud huts; they had to dispense with coal for fuel, since the state of the roads made its transport too costly for their scanty means; they had no shops, and for such drapery and household wares as they could afford to buy they were dependent on the packmen or the hucksters from Newcastle-under-Lyme. Their favourite amusements were bull-baiting and cock-fighting. Any stranger who ventured to appear among such a people, devoid as they were of most of the attributes of civilisation, might consider himself fortunate if he escaped rough usage simply because he was a stranger.

Of conditions such as those to be found in the Potteries at the period in question one gets some glimpses in William Hutton's "History of Birmingham" (1781). He tells of a place called Lie Waste, otherwise Mud City, situate between Halesowen and Stourbridge. The houses consisted of mud, dried in the sun, though often destroyed by frost. Their occupants, judging from the account he gives of them, could have been little better than scarcely-clad barbarians. Of a visit he paid to Bosworth Field in 1770 the same writer says:—
