As requested in your memorandum of September 12, we have conducted an extensive series of tests on the natural sand produced by Kapco Construction Company in Logan County. There was some question regarding the classification of the sand -- whether it would be termed a manufactured, a crushed conglomerate, or a natural sand. I had Mr. George R. Laughlin, Geologist of the Research Division, visit and inspect the pit. A copy of Mr. Laughlin's report to me is attached for your file. He reports that the material being produced is a washed, natural sand and similar in production procedure to pits operating in Carroll, Gallatin and Boone Counties.
