A walk of a mile, on the shore westward of New Passage inn, led us to SUDBROOK ENCAMPMENT, crowning the brow of an eminence which rises in an abrupt cliff from Caldecot level. This work, consisting of three ramparts and two ditches, forms a semicircle, whose chord is the sea cliff; but it is evident, that part of the eminence has mouldered away; and most probable, that the figure of the fortification was once circular. Harris conjectures it to be of Roman origin, and intended for the defence of the port of Venta Silurum (Caerwent). Eastward of the encampment is SUDBROOK CHAPEL, a small Gothic ruin, which was formerly attached to a mansion of Norman foundation. No traces appear even of the site of this structure, which has in all likelihood been swept away by the encroachment of the sea: but several piles of hewn stones near the ramparts are probably its relics. We had another pleasant walk of about a mile from the New passage across the fields to ST. PIERRE, an ancient residence of the Lewis family, descended from Cadivor the great. This mansion exhibits rather an incongruous mixture, in which the modern refinements of sash-windows, &c. are forced upon a Gothic structure upwards of four hundred years old: an embattled gateway, flanked with pentagonal towers, is still more ancient, and is recorded as having belonged to the feudal castle that occupied the site of the present building. Nearly opposite this spot, the great estuary of the Bristol channel, contracting in width, takes the name of the Severn. The appellation of this river arises from the story of a British princess. Geoffry of Monmouth relates, that she was the daughter of Locrine king of Britain, by Elstridis, one of the three virgins of matchless charms whom he took after he had defeated Humber king of the Huns, to whom they belonged. Locrine had divorced his former queen Guendolin in her favour. On his death, Guendolin assumed the government, pursued Elstridis and her daughter Sabra with unrelenting cruelty, and caused them to be drowned in the river, which with some alteration took the name of this innocent victim. Our poets have made a beautiful use of this story: Milton, in his description of rivers, speaks of “The Severn swift, guilty of maiden blood;” but in the Mask of Comus he enters fully into her sad story:
