St. Maws and Pendennis are two fortifications placed at the points or entrance of this haven, opposite to one another, though not with a communication or view; they are very strong--the first principally by sea, having a good platform of guns pointing athwart the Channel, and planted on a level with the water. But Pendennis Castle is strong by land as well as by water, is regularly fortified, has good out-works, and generally a strong garrison. St. Maws, otherwise called St. Mary's, has a town annexed to the castle, and is a borough sending members to the Parliament. Pendennis is a mere fortress, though there are some habitations in it, too, and some at a small distance near the seaside, but not of any great consideration. The town of Falmouth is by much the richest and best trading town in this county, though not so ancient as its neighbour town of Truro; and indeed is in some things obliged to acknowledge the seigniority--namely, that in the corporation of Truro the person whom they choose to be their Mayor of Truro is also Mayor of Falmouth of course. How the jurisdiction is managed is an account too long for this place. The Truro-men also receive several duties collected in Falmouth, particularly wharfage for the merchandises landed or shipped off; but let these advantages be what they will, the town of Falmouth has gotten the trade--at least, the best part of it--from the other, which is chiefly owing to the situation. For that Falmouth lying upon the sea, but within the entrance, ships of the greatest burthen come up to the very quays, and the whole Royal Navy might ride safely in the road; whereas the town of Truro lying far within, and at the mouth of two fresh rivers, is not navigable for vessels of above 150 tons or thereabouts. Some have suggested that the original of Falmouth was the having so large a quay, and so good a depth of water at it. The merchants of Truro formerly used it for the place of lading and unlading their ships, as the merchants of Exeter did at Topsham; and this is the more probable in that, as above, the wharfage of those landing-places is still the property of the corporation of Truro. But let this be as it will, the trade is now in a manner wholly gone to Falmouth, the trade at Truro being now chiefly (if not only) for the shipping off of block tin and copper ore, the latter being lately found in large quantities in some of the mountains between Truro and St. Michael's, and which is much improved since the several mills are erected at Bristol and other parts for the manufactures of battery ware, as it is called (brass), or which is made out of English copper, most of it dug in these parts--the ore itself ago being found very rich and good.
