[Illustration: ROCH CASTLE.] About half-way out rises the lofty isolated tower of Roch Castle, a border stronghold dominating the march-lands that for centuries formed the frontier of this 'Little England beyond Wales.' Built by Adam de Rupe in the thirteenth century, the tall, picturesque old tower forms a conspicuous object for miles around, while at its feet a group of whitewashed cottages cluster around the lowly parish church of St. Mary de Rupe. Crossing the bridge that spans the Newgale Brook, we enter the ancient Welsh province of Dewisland. Presently our venerable quadrupeds are crawling at a snail's pace down a slanting hillside not quite so steep as a house-roof, with the village of Lower Solva squeezed into a crevice beneath our very feet. The situation of this pretty hamlet recalls the Devonshire combe that enfolds with such inimitable grace the village of Clovelly. Groups of bowery cottages cluster around the head of a land-locked haven, which, small as it is, bears no inconsiderable traffic in coal, lime and general produce from the Bristol Channel ports, for distribution throughout the western parts of Pembrokeshire. The rocky, weed-strewn shores shelving up to low, grassy hills overarched by the soft blue sky; a stranded coasting vessel, with weather-stained canvas and rust-eaten anchor, beside a handful of rough fishermen's cottages, present all that an artist could desire to compose a charming picture. [Illustration: SOLVA HARBOUR. FROM AN OLD PRINT.] From the crest of the hill near Upper Solva a wide view of the sea opens out, with a brace of rocky islets off the coast; while far ahead the high lands of Ramsey Isle, Carn Llidi and Pen Beri, raise their graceful undulations above remote Octopitarum, and the wind-swept sandhills that mark the site of legendary Menapia. Coasting along through a rolling treeless country parallel with the course of the Via Julia (the Roman road from Carmarthen), which accompanies us henceforth to the end of our journey, we mount the gentle ascent that leads to the time-honoured 'city,' of which, however, little is seen until we are 'right there,' as our Transatlantic cousins say. Dismounting at the Grove Hotel, we fare forth for our first view of time-honoured Ty Dewi, the city of St. Davids. Strolling leisurely along the quiet grass-grown 'street' of the village-city, we pause now and again to make way for a herd of cattle, or to watch a flock of geese, stubbing, with sinewy necks outstretched, in a damp and weed-grown corner. Presently the roadway widens out, and here stands an ancient stone cross, which, rising from a flight of time-worn steps, marks the central point of this most diminutive of cities.
