The River Conway in North Wales was of considerable importance, even before the Roman invasion, for the Pearl muscle, (the _Mya Margaritifera_ of Linnæus) and Suetonius acknowledged, that one of his inducements for undertaking the subjugation of Wales, was the Pearl Fishery carried forwards in that river. According to Pliny, the muscles, called by the natives _Kregindilin_, were sought for with avidity by the Romans, and the pearls found within them were highly valued; in proof of which it is asserted, that Julius Cæsar, dedicated a breastplate set with British Pearls to Venus Genetrix, and placed it in her temple at Rome. A fine specimen from the Conway is said to have been presented to Catherine, consort of Charles II. by Sir Richard Wynne of Gwydir; and it is further said that it has since contributed to adorn the regal crown of England. Lady Newborough possessed a good collection of the Conway pearls, which she purchased of those who were fortunate enough to find them, as there is no regular fishery at present. The late Sir Robert Vaughan had obtained a sufficient number to appear at Court, with a button and loop to his hat, formed of these beautiful productions, about the year 1780. PILLARS OF COMMEMORATION. The erection of a column or pillar, on the highest point of that ridge of hills, called Blackdown, which separates the county of Somerset from that of Devon, in commemoration of the great victories obtained by the Duke of Wellington, is an inducement to look into history, to see how the nations of antiquity, particularly those of Greece and Rome, rewarded their heroes who signalized themselves by the performance of feats of military courage, valour, and skill.
