That was a time when, as the same authority says, "Liverpool stood nearly at the extremity of the known world." But when the known world was enlarged by the addition thereto of the New World of America, and when commerce with the lands across the Atlantic began to develop, and the industries of Lancashire and Yorkshire to grow apace, the need for improved communications with the port of Liverpool became more and more acute. Such need was the greater, too, because of the fate that was overtaking the much earlier and hitherto far more prosperous port of Chester. Established as a fortress of the first order by the Romans, at the western end of one of their famous roads, and favoured alike by Saxons and Normans, Chester had developed into a flourishing commercial port from which, more especially, intercourse with Ireland was conducted, and it was still the port through which travellers passed to or from Ireland for a long time after Liverpool began to compete actively for the Irish goods traffic. Richard Blome, who visited Chester in 1673, describes it in his "Britannia" as "the usual place for taking shipping for Ireland, with which it has a very great intercourse, and a place of very considerable trade." But, as against the advantage it offered as an inland port, situate twenty-two miles from its estuary, and dealing with the products of an especially productive county, Chester had the disadvantage due to the enormous masses of sand which were driven into the Dee by Atlantic storms, to the full fury and effects of which the open estuary was exposed. This evil began to grow serious soon after the Conquest, and the port of Chester steadily declined as the port of Liverpool steadily rose, the trade lost by the one helping to build up the prosperity of the other.
