A bstract The literature pertaining to microorganisms in clay and the aging of clay is reviewed. Preliminary to attempting to determine the effect of microörganisms upon the aging of clay, six clay bodies have been examined and the numbers and kinds of microorganisms have been determined. The numbers of bacteria found, the variety of species, and then‐growth upon a medium prepared from an extract of ball clay are indicative of their activity. The bacteria identified are typical soil and water organisms. A method has been devised for the examination of the interior of lumps of native clay. One such clay gave no evidence of harboring living organisms beneath its surface, whereas the surface was highly contaminated, probably from external sources.
