LETTER OF TRANSMITTAL Office of the State Geological Survey University, Mississippi December 10, 1940 To His Excellency, Governor Paul Burney Johnson, Chairman, and Members of the Geological Commission Gentlemen: Herewith is Bulletin 42, Tippah County Mineral Resources—Geology by Louis Cowles Conant, Ph.D.; Tests by Thomas Edwin McCutcheon, B.S. Cer. Engr.—the fourth in a series of bulletins that the Mississippi Geological Survey as sponsor to WPA project 4847 pledged itself to publish. The report is the fruit of the splendid cooperation on the part of the civic organizations of Ripley, the citizens of that city and of Tippah County with their State Geological Survey. Many citizens have contributed time and substance, for which the State Geologist is profoundly grateful—especially has Mr. Lee Cox, to mention only one of a number, labored for the success of the survey. The survey, of course, would not have been possible without the WPA grant. The report reveals a number of valuable mineral deposits which await only commercial development to yield a substantial income. The tests show that the Porters Creek clay (middle phase) produces a porous material which, on crushing, forms one of the strongest light-weight aggregates for concrete known to the industry—a material not only light in weight but one which has excellent insulating qualities and one which should supply a great need.
