The washed product (kaolin) is quite mealy to the feel, asthough it contained considerable sericite. Surrounding the kaolin is a ferruginous plastic clay, evidently derivedfrom the gabbro, and containing lumps of weathered nelsonite. Thekaolin washing plant is completely dismantled, hut the product is said tohave been sold for paper manufacture. A test was run first on the crude kaolin (Lab. ]STo. 2169) to determineits properties. The crude kaolin is white, fine-grained, and passes a 100-. ?
