In the account which we have given of that county in the Encyclopaedia, an obliging correspondent has pointed out to us some mistakes. He assures us, that the sea coast, where we undertook the atmosphere to be loaded with such exhalations as produce malignant and intermittent fevers, is remarkably healthy; and he speaks from experience, having lived on that coast for forty years. He assures us likewise, that the Duke of Bridgewater's inland navigation was begun soon after, if not before, the year 1736, and that he (the writer), so early as 1764, was one of a party who sailed up the fonth or estuary a considerable way to see how the coals were worked. The same correspondent has pointed out a few mistakes in our account of

the capital of the county. "That town (he says) carries on no trade whatever with North America, but a very considerable one with Jamaica and the other West India islands, in vessels of from 100 to 500 tons burthen. It exports to these islands all such British manufactures as they have occasion for, Irish linens, and failing provisions of all kinds, such as Irish beef, pork, butter, &c. It trades also to the Baltic, Portugal, Hamburg, &c. to a large amount; and some of its ships with their cargoes have of late been worth from L.60 to L.80,000 sterling. It has, however, no communication by water with the rivers Mersey, Dee, &c. as we have said; the canal reaching as yet no farther than to near Preston in Lancashire." The communication with these rivers is indeed intended to be completed; but whether the scheme be practicable is, according to our correspondent, very uncertain.
