Having been a resident in southwestern Iowa for many years and conversant with several localities in the state of geological interest, the writer has naturally followed closely the publications of the present survey treating of them. In casting about for a subject for some different conclusions which had come to his mind, he thought first of "corrections and additions", but as that savored rather of too much self-assurance the milder form was preferred. Since the writer does not arrogate superior knowledge in the cases, he would simply state his views and leave them to whatever acceptance they may deserve.
