Now look at the map opposite. The shaded portions represent land over 300, 600, or 1,000 feet above sea-level. In the south, the eastern and western uplands slope gradually down towards the bit of white which touches the centre of the bottom of the map and forms what is known as the Cheshire Gap. Through this gap the Midlands lie open to the north-west and to the Cheshire Plain, and over these lower heights naturally passed the great highway from London to the Irish Sea. Chester, built on a rocky plateau at the head of the tidal waters of the Dee and protected on its western side by a natural bend of the same river, was clearly a position of great importance for guarding alike the coast road into North Wales and the roads to the north of England; and there is no doubt that it was held as a fortified post long before the Romans built the Roman city of Deva.
For many centuries this stronghold was one of the chief military outposts and frontier towns of England, not often free from war's alarms, and the sentinels on her walls and watch-towers ever on the look-out for the approach of some new enemy. Chester became the 'base' or head-quarters from which all military campaigns in the north-west, in Wales or in Ireland were carried out, united with the metropolis by the great road that passed through the heart of England, along which armies could march without any difficult hills to cross and hardly a river of any great size to bridge. In later and more peaceful times, for the same geographical reasons, the London and North-Western Railway, the lineal descendant of the ancient 'Watling Street', laid its lines on nearly the same ground as the old highway, and is thus the easiest as well as the most direct of all routes from London to the north-west.

With the exception of the Dee, which rises near Lake Bala in Wales, the rivers of Cheshire have their sources in the eastern or southern uplands. For eight months of the year moisture-laden winds blow from the sea across the Cheshire Plain and deposit their rains upon the hills. In the hilly country of the north-east, where the rainfall is greatest, the water is gathered and stored in a number of reservoirs in Longdendale; and the moist climate is the chief reason why this district is the seat of the cotton industry, for cotton threads become brittle in a dry atmosphere. In the valleys of the Tame and Goyt the abundance of fresh running water from the hills formerly caused many mills for the bleaching, dyeing and printing of calicoes to be erected on or near the streams. Nowadays, however, owing to the greater supply of water brought by pipes from a distance, mills are erected principally on the outskirts of the great towns and nearer the centres of population. Hence in the villages of the Goyt it is no uncommon sight to see the tottering walls of mills that have been abandoned and allowed to fall into ruin and decay.
The combined waters of the Etherow, Tame, and Goyt form the Mersey at Stockport. Only the left bank of this river is in Cheshire. Moreover, for a large part of its course it has been 'canalized', so that it no longer flows between its natural banks, but down the artificial channel of the Manchester Ship Canal. The estuary of the Mersey, which is three to four miles across at its widest point, narrows at Birkenhead to a width of barely three-quarters of a mile. At this point the river is kept open to the largest vessels afloat by constant dredging. Here in the docks you may see ships of all nations, and generally one or more of our huge ocean greyhounds riding at anchor in mid-river or awaiting but the turn of the tide to take out their cargoes of human lives to distant lands.
