CALCIUM SILICATE for building purposes is found three miles east of Pontotoc on State Highway 6, on the Rosalba Lake place. Ten years ago Clarence Bolton, by permission of the highway commissioners, Robbins and Boone, sent fifty pounds of this rock to the highway department at Washington for analysis, and the test showed it to be a high grade calcium silicate rock, suitable for house and road building. Major Ellis, Federal highway engineer, at Muscle Shoals, Alabama, stated that this was the only rock of this grade found in the south, and three or four of the eastern states. He further stated that he had used this rock in France during the World War in building highways for the army, and that it was the most satisfactory highway building rock he had ever used. It not only made a permanent road surface, but would set up in twenty four hours so that traffic could pass over it. In this rock formation a great variety of curiously-formed sea shells and unclassified fossils are found (1)
