The voyage up the Bristol Channel is singularly romantic and beautiful; but the coast is exposed to all the fury of the Atlantic, and the surf against the cliffs is distinctly visible at Swansea. The steamers now keep close along shore, in a channel inside the Nass Sands, which form an extensive and dangerous bank to seaward. The contrast between the tumultuous masses of breakers over these sands, when the wind is fresh, and the calmness of the narrow channel we are traversing in security, is very striking. These sands, and another large shoal, called the Skerweathers, have been fatal to many vessels. A large West Indiaman, with a cargo of rum and other valuable produce, was lost a few years ago on a rock called the Tusca, which disappears at high-water; and in 1831, this coast was fatal to the steamer _Frolic_, in which all the crew and passengers, amounting to nearly eighty persons, perished. The coast near Porthcaul appears at Swansea to be the eastern extremity of the bay; but the bluff point called the Nass, about eight miles further, is literally so. The coast onwards, past the Nass-point, as observed in the admirable Engraving annexed, is almost perpendicular, so as closely to resemble a lofty wall, in which the limestone rock is disposed in horizontal strata. When the sea runs high in this quarter, the scene, as may be readily conceived, is truly terrific-- "And not one vessel 'scapes the dreadful touch Of merchant-marring rocks." MERCHANT OF VENICE. [Illustration: CARDIFF.] CARDIFF, GLAMORGANSHIRE. "Here British hearts the arms of Rome withstood, Repulsed her cohorts with their native blood; Till Caradoc and independence fell, And freedom shrieked in CARDIFF'S citadel-- And Cambria's heroes, rushing on the glave, Died gloriously for her they could not save!" The county of Glamorgan, of which the principal town is represented in the accompanying plate, abounds in historical sites well adapted for the pencil, and furnishing the reader with many interesting facts and traditions. The southern portion of the country is remarkably fertile, highly cultivated, and presents to the stranger a long succession of luxuriant corn-fields, verdant pastures, and animated pictures of rural happiness and independence. It would be difficult to find any tract of land in Great Britain that can surpass the Vale of Glamorgan in richness of soil, or in soft and graceful scenery. This favoured region extends the whole length of the county--from the base of the mountains on the north to the shore of the Bristol Channel on the south-west. It presents throughout a most gratifying proof of what may be accomplished by judicious management, when soil and climate are both in favour of agricultural operations.
