Even in the rich coal regions of Pennsylvania pearls are found. Possibly the most productive section in that State has been the headwaters of the Schuylkill River in the vicinity of Tamaqua, Quakake, and Mahony City. Of the tributaries of the Schuylkill, those contributing largely to the yield have been Lewiston, Nipert, Still, Locust, and Hecla. These rise in the mountains and are rivulets of fair size by the time they reach their common outlet. [Illustration: PEARL-BEARING UNIOS From the Mississippi Valley The upper pictures show the two valves of the same shell, and the pearl is detachable ] The original pearl finds in the Schuylkill date from half a century ago, when they were secured by farmers who used the mussel shells in removing hair from the hides of slaughtered pigs. During the Mississippi pearling excitement in 1897, several persons from New York, who were summering in Schuylkill County, searched the small streams for pearl-bearing mussels with such success that within a short while many farmers became enthusiastic hunters during their spare time. Half a dozen or more men did very well, their catch amounting to thousands of dollars’ worth. Mr. Frank M. Ebert, of Quakake, has put most of his spare time in the business in the last ten years, and has secured many good pearls. It is estimated that the total catch in Schuylkill County alone approximates $20,000 at local values. So actively has the search been conducted that at present few adult mussels of the pearl-bearing species remain, and a day’s work may result in finding less than a dozen. The best price reported as received by a local fisherman was $200 for a twenty-grain pearl in the year 1904. Many individual specimens have been sold at prices ranging from $100 to $175. It is claimed that a pearl sold by a fisherman in Schuylkill for fifty cents was later marketed in Philadelphia for $125, and with slight mounting was ultimately sold for $1600. The most attractive weigh from ten to twenty grains each; larger ones have been found, weighing up to thirty-eight grains, but as a rule the luster is not so good as that possessed by pearls of medium size. The common colors are dark blue, pink, lavender, and white. A few are black and some are brown. The brown pearls are seldom of value, owing to deficiency in luster. In Maryland pearls have been collected from the brooks near the head of Chesapeake Bay, and especially in Kent and Cecil counties. These are of almost every conceivable color, ranging from a clear white to a dainty pink, and to very dark colors, especially bronze and copper. Most of them are too small for commercial value, and only a few reach sufficient size to command more than $5 or $10 each, but single specimens have sold as high as $50.
