Another pearl hunt developed along the Little Miami River in Ohio from the finding of several fine pearls near Waynesville in 1876. This reached its height in 1878. In 1880, pearls began to come into the New York market from the West and South. Immense beds have been fished in the White, Wabash and Ohio Rivers in Indiana. In the summer of 1889 a number of fine pearls were found in the south-western corner of Wisconsin, in Crawford, Grant, Lafayette and Green counties. Not only were they notable for extraordinary luster, but many were of beautiful color. The sale of some at prices which seemed fabulous to the people of that section, when it became generally known, caused such a scramble for them by the natives that the streams were rapidly denuded of mussels, and that section has become of much less importance than others since developed. Prairie du Chien is the center of the Wisconsin market, from which point the shells are distributed to the button factories. The following year (1890) pearl-bearing mussels were found in several of the central counties of Illinois—McLean, Tazewell and Woodford, in the Mackinaw river and tributaries, but no discovery equalling that of Wisconsin occurred until 1897 when the Arkansas beds were discovered. A peculiarity of this district is that whereas the unio is usually most abundant in swift clear water having a sandy or gravelly bottom, many are found here in the mud. They have been taken over a wide territory from the rivers and streams of the eastern half of the state, including the Black, White, Cache, St. Francis, Ouachita, Saline and Dorcheat rivers, and in the valley of the Arkansas. Following this were finds in Indian Territory, Missouri, Georgia and Tennessee, the latter being the most prolific. The finest pearls in Tennessee are found in the fluter, or lake shell, which is the same as the mussel known on the Wabash as the wash-board. A yellow shell is found in the Clinch River similar to the mucket of Arkansas, from which pearls are taken. Unlike the pearl oyster, the unio seems to be more prolific of pearls in the shallows and riffles near the edges of the rivers. Most of the fine pearls are found between the pallial line and the lip in the free portion of the mantle. Those found within the pallial line, where the mantle is attached to the shell, are seldom as lustrous or perfect. Pearls are found in many States besides those mentioned, but the fishing is done quietly and in some cases the sources of supply are known to only a few who in the marketing of their pearls carefully avoid giving any information. This is particularly true of some of the eastern states. Streams in the Northwestern section of New York State are regularly fished, but without excitement. The large fisheries of the Mississippi and West are fished principally for the mother-of-pearl in the shells. As with some of the marine fisheries, the pearl is regarded as an extra.
