CONWAY QUAY. The district of Conway is mostly agricultural, and possesses no distinct manufactures by which the prosperity of the town and its population can be greatly promoted. A few small trading-vessels belong to the port; and here also ships of burden are occasionally repaired. The great improvement to the harbour is the erection of the quay; and the channel of the river having been deepened, and every impediment to the navigation removed, it may be anticipated that a speedy increase of trading intercourse will succeed its former languor and inactivity. The exports consist chiefly of timber, slate, and lead; and the imports, of coal from Flint and Liverpool, and of tea, sugar, cotton, with various other articles of domestic consumption. The chain-bridge, which constitutes so beautiful a feature in the picture of Conway, was erected by Mr. Telford, of whose genius Wales possesses several of the noblest monuments. That immediately under notice--constructed on the same principles as the bridge over the Menai, but much smaller in its proportions--is three hundred and twenty feet between the supporting towers, and eighteen feet above high-water mark. Nothing can be more elegant and beautiful, as it appears lightly spanning the river, and suffering the eye to penetrate its net-like fabric, so as scarcely to offer an obstruction to the landscape which shines through it. The scenery at this point is exceedingly interesting, and presents the works of nature, and art, and human genius, in striking combination.
