Nothing worthy of commemoration took place during the two following days, save that myself and family took an evening walk on the Wednesday up the side of the Berwyn, for the purpose of botanizing, in which we were attended by John Jones. There, amongst other plants, we found a curious moss which our good friend said was called in Welsh Corn Carw, or deer’s horn, and which he said the deer were very fond of. On the Thursday he and I started on an expedition on foot to Ruthyn, distant about fourteen miles, proposing to return in the evening. The town and castle of Ruthyn possessed great interest for me from being connected with the affairs of Owen Glendower. It was at Ruthyn that the first and not the least remarkable scene of the Welsh insurrection took place by Owen making his appearance at the fair held there in fourteen hundred, plundering the English who had come with their goods, slaying many of them, sacking the town and concluding his day’s work by firing it; and it was at the castle of Ruthyn that Lord Grey dwelt, a minion of Henry the Fourth and Glendower’s deadliest enemy, and who was the principal cause of the chieftain’s entering into rebellion, having in the hope of obtaining his estates in the vale of Clwyd poisoned the mind of Henry against him, who proclaimed him a traitor, before he had committed any act of treason, and confiscated his estates, bestowing that part of them upon his favourite, which the latter was desirous of obtaining. We started on our expedition at about seven o’clock of a brilliant morning. We passed by the abbey and presently came to a small fountain with a little stone edifice, with a sharp top above it. “That is the holy well,” said my guide: “Llawer iawn o barch yn yr amser yr Pabyddion yr oedd i’r fynnon hwn—much respect in the times of the Papists there was to this fountain.”
