In 1694, the prodigious phenomenon of fire, or kindled exhalation, which disturbed the inhabitants of this neighbourhood, is both singular and extraordinary; sixteen ricks of hay, and two barns, were burnt by a kindled exhalation, or blue weak flame, proceeding from the sea: this lasted about a fortnight or three weeks, poisoning the grass, and firing it for the space of a mile. It is extraordinary, that it had no effect on the men, who interposed their endeavours to save the ricks from destruction, even by running into it. For a more accurate account of this singular phenomenon, I refer my readers to the _Philosophical Transactions_, No. 208, and likewise to the Addenda, in Cambden: suffice it to say, that the air and grass was so infected, that it occasioned a great mortality of cattle, horses, sheep, and goats. The various conjectures that have been formed, to account for this kindled exhalation, seem to be very unsatisfactory; something similar to this, both in the appearance and in the effect, happened in France in the year 1734. As, from the unfavourableness of the weather, we had not contemplated the rich scenery between Barmouth and Dolgelly, with that nice investigation which it deserved, we determined, by again returning to our obliging landlady at the Cors-y-gedol Arms, to seize the opportunity of again admiring its beauties; and, by taking a more circuitous route to the Vale of Festiniog, pay that attention to the Falls of Doll-y-mullin, Moddach, and Caen, which they so deservedly require. This second saunter we found by no means tedious: the scene seemed perpetually changing at every unexpected curvature of the road; and the rude features of the mountains appeared to assume new forms, as the winding presented them to the eye in different attitudes, whilst the shifting vapours, which partially concealed their minuter grandeur, assisted the illusions of the sight. Amidst new woods, rising in the majesty of foliage, the scattered cottage, with its bluish smoke curling high in the air, was frequently rendered interesting by its neat simplicity: and served to constitute the romantic beauties of this picturesque saunter.
