NA RYON, NORTH WALES, 20 miles (S. by El from Carnarvon containiniF 523 inhabitants, an with Port Madoc, 1358. This place,
which is of very, recent -origin, and a signal instance of the triumph of public-spirited perseverance over accumulated
and apparently insurmountable local difficulties, derives its name from its patriotic and enterprising founder, the late
William Alexander Mattocks, Esq. This gentleman, having projected a plan for regaining from 'the sea a portion of land on
the western side of the wide sandy estuary called the ,6 Tmeth Mawr," purchasedithe estate of Tam-yr-Alit, in the
immediate vicinity, in 1798, and. in 1800 succeeded in recovering a:tract of nearly two thousand acres of rich land, then
forming Penmorva marsh, -which Bow produces excellent crops of -wheat, barley, and clover. Encouraged by the success of
his first attempt, Mr. Madocks was induced to undertake the more arduous enterprise of reclaiming the whole of the Traeth
Mawr, and for this purpose he obtained, in 1808, an act of parliament vesting in him and in his heirs the whole extent of
these sands, from Pont Aber Glislyn, at their head, to the point at Gest, at their lower extremity. According to the
provisions of this act, Mr. Madocks received a grant of two thousand acres in fee, and was to possess one-fifth part of
the land recovered from the sea, or secured from injury by the floods, the remainder to go to the freeholders who claimed
right of common on the adjoining marshes. Notwithstanding the numerous unforeseen obstacles which threatened to frustrate
the undertaking, Mr. Madocks succeeded in constructing across the mouth of the Traeth Mawr, at the eastern extremity of
Cardigan bay, an embankment of earth and stones, nearly a mile in length, from north to south, varying from one to four
hundred feet in breadth at the base, and diminishing gradually to a breadth of thirty feet at the summit, which is a
hundred feet high from the foundation. By means of this embankment, which, having an excellent road along its summit,
forms a line of communication between the counties of Carnarvon and Merioneth, a tract of more than two thousand seven
hundred acres of land was gained from the sea, besides a vast extent of adjoining land, which was before overflowed by the
tides, but is now, by draining, rendered susceptible of cultivation. This arduous enterprise was completed in 1811, at an
expense of more than £100,000; and, including the lands previously recovered, not less than seven thousand acres have
been obtained, of which six thousand are now cultivated. The TOWN is situated on a portion of the tract first recovered
from the sea, and is built on the sides of a spacious quadrangular area, having in the centre a lofty stone column, round
the pedestal of which is a flight of four steps. The houses are of handsome appearance; a commodious hotel has been
established; and the town promises, when the plan is fully completed, to be a great ornament to this part of the coast.
It is sheltered on the north by a chain of formidable rocks, that line the side of the road leading from Bethgelart, which
approaches it from the east, after winding its way through the grand mountain pass of Pont Aber Gladyn, at the foot of
which is seen a picturesque bridge, springing from rock to rock, and forming a means of communication between the counties
of Merioneth and Carnarvon, with the river Glislyn meandering beneath: on the west the town is approached by the road
from Pwllheli, which passes through the neat little village of Llanystyndwy and the ancient town of Criccieth. Tan-yr-Alk,
the seat of the late W. A. Madocks, Esq., is a spacious modern mansion of elegant design, situated on an elevated rock
over. looking  the town; it is surrounded with thriving plantations, and presents, with its entrance lodge of neat and
appropriate design,easing and picturesque appearance. Morva Lodge, and TwatPr-bwIch, erected also by that gentleman, are
handsome villas in the immediate vicinity- Moel-y-Giu, which is partly in Ynyscynhaiarn parish, and partly in that of
Trevlys, is an isolated rocky eminence, about a mile from the town, and contiguous to the sea, above which it attains an
elevation of nearly 100 feet. The ascent to the top is easy, and the prospect from it is exceedingly grand and extensive,
embracing the whole of Cardigan bay; on either side of the entrance to Port Madoc are seen the interesting ruins of the
castles of Harlech and Criccieth; and the interior view presents Snowdon and its group of elevations, known by the name of
the Snowdonian mountains, with those of Merioneth. With a view to promote the commercial interests of the town he had
founded, Mr. Madocks, in 1821, obtained an act of parliament for improving the navigation of this part of the bay whereon
it is situated, under the provisions of which he rendered it accessible to vessels of three hundred tons' burthen, which
can now lie here in safety, and constructed commodious quays and wharfs for the landing and shipping of goods. The last
improvement carried into effect was the erection of Port Madoc, containing 830 inhabitants, about one mile from the town,
where many good houses have been built, and a considerable trade is now carried on: the principal exports are slates and
copper-ore, the former brought from the Festiniog quarries, and amounting to about thirty thousand tons annually shipped;
the chief imports are timber, coal, and lime. A railroad from the Festiniog quarries, and the mines in the neighbourhood,
to this place, has been lately constructed by a company formed under an act passed for that purpose; it is carried along
the embankment, with a good road for travelling on its north side, well sheltered from the sea, being 8 feet lower than
the summit. Lead-ore has been discovered at Gest, near the town; and an excellent road has been constructed by Mr.
Madocks from Aber Glislyni through Tremadoc, to Porthdinllaen on the western coast of Carnarvonshire. Fairs are held
annually on the 2nd Friday in February, April 13th,oisse 30th, December 6th, and November 12th, the hiring day for
servants. On the east side of the area a commodious market-house has been erected, above which is a handsome assembly-
room. Mr. Madocks also built, at his own expense, a handsome small church, in the later style of English architecture,
with a lofty spire, which forms an interesting object as seen from the coast; and divine service is regularly performed
in the English language, every Sunday, which is a great accommodation to families residing in the neighbourhood, as there
is no other church within twenty miles, where the service ie conducted in English. The road from Tremadoc to Bethgelart,
along the northern side of the Traeth Mawr, passes, as already mentioned, for some distance under perpendicular cliffs of
great height, in which are numerous chasms and fissures; and after heavy rains, or long-continued frosts, immense masses
are sometimes detached from the impending precipices, and fall with a tremendous crash, bestrewing the way with fragments,
sometimes of sufficient magnitude to obstruct the passage. The road commands to great advantage the scenery of the
Merionethshire side of the Traeth, and affords a delightful ride to Pont Aber Glfislyn and its vicinity.
