In Scotland, especially to the northward, in all rivers running from lakes, there are found mussels that have pearls of more than ordinary merit, though seldom of large size. I have purchased many hundreds, till lately the wearing of real pearls coming into fashion, those of Scotland have increased in price greatly beyond their value, and superior often to the price of oriental ones when bought in the east. The reason of this is a demand from London, where they are actually employed in work, and sold as oriental. But the excellency of all glass or paste manufactory, it is likely, will keep the price of this article, and the demand for it within bounds, when every lady has it in her power to wear in her ears, for the price of sixpence, a pearl as beautiful in colour, more elegant in form, lighter and easier to carry, and as much bigger as she pleases, than those famous ones of Cleopatra and Servilia. I shall only further observe, that the same remark on the shell holds in Scotland as in the east. The smooth and perfect mussel shell rarely produces a pearl, the crooked and distorted shell seldom wants one. I shall here mention a very elegant sort of manufactory, with which I cannot positively say the ancients were acquainted, which is fineering, or inlaying with the inside of the shell called mother-of-pearl, known to the dealers in trinkets all over Europe, and in particular brought to great perfection at Jerusalem. That of Peninim, though the most beautiful, is too fragil and thin to be employed in large pieces. It is the nacre, or mother-of-pearl taken from the Lulu el Berberi, or what is called Abyssinian oyster, principally used in those fine works. Great quantities of this shell are brought daily from the Red Sea to Jerusalem. Of these all the fine works, the crucifixes, the wafer-boxes, and the beads, are made, which are sent to the Spanish dominions in the new world, and produce a return incomparably greater than the staple of the greatest manufactory in the old. _THE END._ [Illustration: _To_ THE KING.
