"It is perceived by many grave and wise men, as well of the city of London as of the country, that it were very commodious and profitable both for the city and the country that the river of Lea, otherwise called the Ware river, might be brought within the land to the north part of the city ... through such a convenient and meet cut as may serve for the navigation of barges and other vessels, for the carrying and conveying as well of all merchandizes, corn and victuals, as other necessaries from the town of Ware and other places to the city ... and also for tilt-boats and wherries for conveying of the Queen's subjects to and fro, to their great ease and commodity."

The Corporation of the City of London were authorised to construct and act as conservators of the new channel, and Commissioners in Middlesex, Essex and Hertfordshire were again entrusted with the duty of freeing the river from shoals and shallows.

A number of other Acts relating to the Lea followed, but mention need only be made here of one passed in 1779 which stated that, inasmuch as the trustees appointed under earlier enactments could not, without further advance in the rates they were already empowered to enforce, liquidate the charges falling upon them in respect to the outlay for works done on the river, they were authorised to increase those rates.

In the seventeenth century, especially in the period following the accession of Charles II. to the throne (1660), much attention was paid to river improvement. A rapid expansion of commerce, of industries and of wealth had followed alike the planting of colonies in the West Indies and on the continent of North America, the development of home manufactures, the reclamation of many waste spaces through the operation of enclosure Acts, and the improvements brought about in cultivation. The need for better means of communication in order to open up districts then more or less isolated, to provide better transport for raw materials and manufactured goods, and to facilitate the carriage of domestic and other supplies needed by the increasing population, thus became more and more apparent.

In many instances the condition of the roads and the prejudicial results upon them of heavy traffic were adduced as the main reason for a resort to improvements of river navigation. An Act (21 Jas. I., c. 32), passed in 1624, for deepening the navigation of the Thames from Bercott to Oxford, stated that it was designed "for the conveyance of Oxford freestone by water to London, and for coal and other necessaries from London to Oxford, now coming at a dear rate only by land carriage, whereby the roads are becoming exceedingly bad." It was further stated, in the preamble, that "the said passage will be very behoveful for preserving the highways leading to and from the said university and city and other parts thereabouts" which, owing to "the continual carriages by carts," had become dangerous for travellers in winter, "and hardly to be amended or continued passable without exceeding charge." In 1739 there was passed an Act (14 Geo. II., c. 26), "for the betterment and more easy and speedy portage" on the Medway of timber from the woods of Sussex and Kent, which timber could not be "conveyed to a market but at a very large expense by reason of the badness of the roads in these parts."

Various far-seeing, patriotic and enterprising individuals took a leading part in pioneering the movement in favour of improved river navigation which, for a period of about 100 years—until, that is, the advent of the canal era—was to be developed with much zeal and energy, though not always with conspicuous success. Especially prominent among these pioneers were William Sandys, Francis Mathew and Andrew Yarranton; and it is only fitting that some mention should here be made of these three worthies, each of whom shared the fate of so many other pioneers, in so far as he was a man in advance of his time.

Sir William Sandys, of Ombersley Court, in the county of Worcester, obtained, in 1636, an Act of Parliament which granted powers for making navigable the Warwickshire Avon from the Severn, at Tewkesbury, to the city of Coventry, and, also, the Teme, on the west side of the Severn, towards Ludlow. Some of the works thus carried out are still rendering good service. In 1661 he secured further Acts for making navigable the rivers Wye and Lugg and the brooks running into them in the counties of Hereford, Gloucester and Monmouth. Here he anticipated much of what was to be done a century later by Brindley, in connection with canal construction, inasmuch as he obtained powers not simply to deepen the beds of the rivers and to straighten their courses, but to construct new channels, to set up locks, weirs, etc., to provide towing-paths, and to dig new channels where required. This last-mentioned proposal constituted, as will be seen later on, the idea that led up to the eventual transition from navigable rivers to artificial canals, the new "cuts" on the former being the connecting link between the two.

The Wye was found to be an exceptionally difficult stream to tame and control, and Sandys' attempt to make it navigable by locks and weirs on the pound-lock system was a failure. The scheme was, however, afterwards carried through on different lines; and in summing up the results John Lloyd, Junr., says in "Papers Relating to the History and Navigation of the Rivers Wye and Lugg" (1873):—

"Although, through the uncertainty of its stream, the Wye was never brought to answer the purpose of a regular conveyance, its navigation has proved of great service throughout the county of Hereford. Throughout the last[[21]] century most of the coal consumed in Hereford and its neighbourhood was brought up in barges after a flood. Various other heavy articles, such as grocery, wines and spirits, having been first conveyed from Bristol to Brockweir in larger vessels, were carried up thence in barges at a much easier rate than by land carriage. In return the boats were freighted with the valuable oak timber, bark, cider, wheat, flour and other produce of the county. The opening of the towing-path for horses by the Act of 1809 gave a further impetus to navigation, and especially to the trade in coal from Lidbrook, and while every river-side village could boast of its quay and its barge, the quay walls at Hereford were thronged with loading and unloading barges....

"Since the opening of the Hereford, Ross and Gloucester Railway, in 1855, and the consequent dissolution of the Towing-path Company, nearly all navigation on the Wye above Monmouth has ceased."
