In the book of Anderson Co., Historical Sketches by Katherine Baker Hoskins.there are about 4 pages on the Clinch River, floods & pearls. When I was there in the 1990's I wanted to buy one as my great grandfather & his brother ran a ferry across the river. None were to be found & I don't think they are in the river any more but not sure about that. Can you get the book ??? Phyllis
