Letter from Thomas Gold to Dr Gene Simmons, M.I.T. Buiding 54-314, Cambridge, Massachusetts Encloses some material that may contain points to be incorporated in his next booklet, Gold knows his views are not in the mainstream of opinion, but thinks th4 book would gain in interest if the difficulties of interpretation and the divergent opinions are mentioned. Hence, for example, the layering in core samples adn the embedding of rocks may deserve comment. 14 October 1971
