Book excerpt: Excerpt from The Upper Ordovician Rocks of Kentucky and Their Bryozoa Sir: - I have the honor to herewith submit for publication a report on the Upper Ordovician Rocks of Kentucky and their Bryozoa, by Professor John M. Sickles. This is a contribution toward the proper classification of our geological formations, which, as has been stated in another report, is necessary for an intelligent and adequate understanding of their economic values. In order, for example, that we may be able to estimate the depth below the surface at which a known oil or gas-bearing stratum may be found, we must be able to identify the beds seen at the surface and know their relations to other beds in the series of which the oil-beariug stratum forms a member. The identification of particular beds or a groupof bedsiuaseries of stratified rocks largely depends upon a knowledge of their characteristic fossils. There is less general knowledge of bryozoa than of other fossil forms, and yet they are often the only trustworthy means for discriminating some of the minor divisions of a formation series. The Surrey has been fortunate in having the services of Professor Nickles in dealing with that difficult feature of our classification studies, as they relate to the Upper Ordovician or Cincinnatian rocks. The general study of the Cincinnatian series is in the hands of Professor Aug. F. Foerste. His report, which will include many plates, is in course of preparation. It seems well to here notice two suggestions made by Professor Nickles. Calling attention to the fact that the Eden beds are the ones that constitute the least fertile of the Ordovician lands, he suggests that a systematic replanting of timber in the Eden areas would be of exceeding value to the State.
