During the summer of 1888 a deep well was drilled at Sigourney, in Keokuk County. Captain Parker, who was at that time mayor, carefully preserved samples of the different strata passed through. These samples have recently been re-examined, and form the basis of the following notes. While the unreliability of records derived from the ordinary or churn drill is fully recognized, it is believed that the care with which these samples were selected and preserved, at least considerably reduces that element of doubt. Previous accounts of this record have been published in the local newspapers, and re-published by C. H. Gordon in the American Geologist. Recent studies in the region, as well as a revision of the material, give, however, considerable information not available at that time.
