A microscopic examination was made on those clays and shales of North Carolina which gave most promise of future development in the structural clay products industry. The more common minerals were determined rather than the rare ones which did not occur in sufficient quantity to affect the quality of the clay. The work showed clay substance to be the most abundant material present, followed by quartz, red and yellow iron oxides, muscovite through sericite to hydromica, and epidote, with smaller amounts of rutile, biotite, titanite, tourmaline, and zircon. Diatoms were found in two cases and kaolinite in one.
