LANCASTER, 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 salted 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.
