Let us fancy ourselves therefore, on a bright April morning, riding along with a friend--a stranger like ourselves--on the high road from Swansea into the interior of the peninsula. After cantering over about seven miles of hill and valley and common, we entered a woody defile, and at last opened, to use a nautical phrase, the "Gower inn," (eight miles) which was built, we were told, expressly for the convenience of tourists. After ascending a tremendous rocky hill, for road it cannot be called, about a mile onwards, Oxwich Bay bursts at last in all its beauty upon our sight. In our inquiries during the day, of the few passengers we met, as to the distance of the village of Penrice, the intended limit of our day's excursion, we were forcibly reminded of the "mile and a bittock" of the north. The country is very thinly populated here: at last we came in sight of the grounds of Penrice Castle, the beautiful mansion of Mr. Talbot, the member for the county; the entrance to the park is between two of the towers belonging to the extensive and picturesque remains of the ancient Castle of Penrice, which stands close to the road. Sixteen miles from Swansea, after "curses not loud but deep" upon Welsh roads, we reached the sequestered village of Penrice, which stands on a wooded eminence of no easy access, overlooking the eastern shore of Oxwich Bay.
