The chemistry department of Iowa Wesleyan College first began a preliminary chemical analysis on some South-Eastern Iowa coals, along the conventional lines of proximate analyses.” Samples in the exhibit shown at the Academy meeting included coals from some of the earliest coals mined west of the Mississippi river, coming from mines in Van Buren County near Bonaparte and Farmington. Analysis of these specimens showed that they ran fairly true to the pattern set forth in the Iowa state mine inspectors\u27 reports, such as that for the two-year period ending Dec. 31, 1945
