We rode all the way upon the Roman road from Manchester to this place: it is the common road throughout, except a little near Altringham: that market-town has caused it to be left, by a common; but we recover it again at Bowden hill, whence we had the prospect of it a long way before us, in a strait line: it leaves Altringham a little to the east, passes west of Rotherston mere, close on the west of North Tabley house, and so directly to Northwich, which therefore must be of necessity the _Condate_ of Antoninus. The Britons called these wiches, or places of salt-works, _Hellath_, from _heli_, salsugo: the last syllable seems to be in _Condate_: then it will signify the principal salt-work, _cond_, caput. Part of the road hither, by the Bollin river, they call Wash-way, from its wateriness; which shows the derivation of our country washes. This town stands in an angle made by the Weaver river and the Dane, both which are passed by bridges, sometimes overflow with great fury. South of the bridge, upon the high ground by the Chester road, is a great _tumulus_, or keep, of Saxon work, called the Castle. This is a pretty large town, but meanly built, depending intirely upon the salt trade: here are the strongest springs of brine, and the wonderful mines or rocks of salt, 60 yards under ground, which they work like coal-mines: how far they extend, is not known. I doubt not but there are many more all over this country: these are found out by chance, not many years since: they carry it into Ireland, Wales, and other places; and boil it up afresh with seawater. It is a most liberal gift of Nature, a compendious way of making salt; these springs being stronger than the ocean: the rock salt stronger than they; for it is perfect salt, transparent like crystal: it lies not in veins, or _strata_, as other minerals, or metals; but a solid rock, of unknown dimensions, which they hew away with steeled pick-axes, leaving pillars and spaces, as big as a cathedral. Poplar-trees are plentiful in this country: they all lean eastward, as continually pressed by the west winds from the sea.
