Specimens of Block coal collected during the past 5 years for miospore analysis have aroused the curiosity of both geologists and the author. Many reddish-brown specks have been observed on bedding planes with the naked eye. Because of their abundance in the Block coals, megaspores were believed to provide an additional statistical aid in correlating coals. Finally, during the summer of 1954, a study of these large spores was undertaken. Unfortunately, the preliminary work, especially preparing coal samples for study and assembling widely scattered literature on megaspore analysis, proved more time-consuming than was anticipated. The author, however, expects to continue these studies and hopes that the later report will provide an additional means of correlating coals.
