The next expedition we shall recommend is a visit to the Llanllyfni Slate Quarries, and the Nantlle (or as they were formerly called the Bala Deulyn) Lakes, then proceed by Drws y Coed, to the Bethgelert road, and return by Quellyn Lake and Bettws Village to Carnarvon. Part of this rout, particularly from the Quarries to the main road, leading from Carnarvon to Bethgelert, will not admit of a four-wheeled Carriage, and it would be difficult to take even a Gig along that portion of it. The whole of this circuit, as before described, round the huge Mynydd-mawr, (a mountain which forms so remarkable a feature in the landscape from Carnarvon) will make a distance probably of about one and twenty miles. Persons who may be induced to examine this interesting part of the County, would do well to hire ponies at Carnarvon, and set off after an early breakfast; they would then be able to return by three or four o’clock. The first part of the journey, for two miles and a half, is along the Pwllheli road; about that distance, (a few yards beyond a small bridge) the turn on the left must be taken, afterwards the Slate Carts (of which the stranger will meet with a great number) will be a sufficient direction. It is thought necessary to mention these particulars, as there are neither mile stones nor finger posts to point the way, and but few of the country people understand the English language; the stranger would therefore act wisely to engage a good intelligent guide, well recommended by some gentleman resident at Carnarvon. Pont Seiont (above and below which the Scenery is very beautiful) is a bridge within a short mile of the town, and between which and Pont Newydd, (another bridge over the River Gwyrfai, a mile further,) there is a Manor belonging to the Bishop of Bangor, called _Castellmai_, the principal Freeholders in which, 1647, were the following, as appears by the Extent Book: Dr. Williams, late Archbishop of York, W. Glynn, Esq. John Bodvell, Esq. Hugh Gwynn, Esq. John Robins, Esq. William Spicer, Esq. Sir W. Williams, Bart. Richard Prytherch, Esq.; Parish of Llanfaglan, ditto, John Bodvell, Esq. Wm. Foxwist, Esq. Thomas Glynn, Esq. Hugh Griffith, Esq. Richard Prytherch, Esq. John Robins, Esq.: Llanwnda Parish,—William Foxwist, Esq. Hugh Gwynn, Esq. Thomas Williams, Esq. and Thomas Glynn, Esq.
