The records of pearl fisheries in the province of Hanover were traced by Von Hessling as far back as the sixteenth century, when they were prosecuted in the Aller, Ovia or Om, Lua or Low, and in the Seva in the district of Lüneburg. During the reign of Christian Ludwig (1641–65) and in that of George William (1666–1705), pearl fishing was carried on by the state, and old records of the former district of Bodenteich note the customs and practices of that period and of earlier times, and the implements employed. In 1706, for instance, 265 clear and 292 imperfect pearls were taken by three official fishermen from the Gerdauerbach. Gradually, however, owing to indifferent management, the brooks yielded less and less; the government seems to have entirely abandoned supervision of them, so that, according to Taube’s “Communication,”[215] slight results were obtained in 1766; indeed, only a few pearls could be shown as curiosities.[216] Regarding the condition of the Hanoverian pearl-brooks, especially of those in the vicinity of Uelzen, Möbius wrote: “Uelzen lies at the confluence of eleven small rivulets, three of which, the Wipperau, the Gerdau and the Barnbeck, contain pearl-mussels. Fishing has been pursued here for centuries, and there exists an old regulation of the sixteenth century in regard to the pearl fisheries in the Ilmenau. Even at the present day, hundreds of pearls are found here which command a good price when they are bright and of good form. These either have a silvery sheen or they are of a reddish color. The season for fishing is during the months of July and August. The pearls are usually found in deformed shells. Their shape varies greatly; most of them are flat on one side. Naturally those which are spherical are the best, but the pear shapes are highly prized.” Möbius frequently failed to find one pearl in a hundred shells, but at other times he came across six or eight in this quantity. Most of the mussels are found in the deepest places, especially near the banks of the streams. One end of the shell usually projects out of the sand. The fisherman is represented as feeling about the bottom with his feet, and when he finds a shell, he seizes it between his toes, picks it out, and then places it in the basket suspended from his neck.[217] [Illustration: MITER OF PATRIARCH NIKON Presented by the Czar Alexis Mikhailovitch and the Czarina Marie Illiinichna.
