Excerpt from A Preliminary Report on the Goal Deposits of Missouri: From Field Work Prosecuted During the Years 1890 and 1891, With 131 Illustrations Of especial value in this report are the records of the various deep shafts and drill holes Which are included. These were furnished by many different individuals, and, in each case where the results are quoted, recognition of this assistance is expressed. With a few excep tions, the individuals and corporations of the State have generously contributed such results in a free. Pnblic-spirited manner. The im portance of furnishing such records to the Survey, where they may be kept on file for ready reference, cannot be too strongly emphasized. Hundreds of such holes have been put down in the State for various purposes. And from comparatively few of such are reliable results now available. Such holes are generally sunk for a definite purpose and when that end is reached it occurs to few that the results may still be valuable for other purposes. But this is almost always the case. Whether a thick coal bed be encountered or not a good record estab lishes aseries of facts concerning the geology of the locality and is, hence, valuable. For instance, the record though apparently barren of results of economic value, may show that the drilling stopped in a certain lime stone, which, by comparison with a record obtained elsewhere, we know is 20 or 50 feet, as the case may be, above a certain valuable coal bed. Hence, from the study and comparison of these two records we are able to predict the probable existence of workable coal within a short distance of the bottom of the hole. Again, the hole may have penetrated rocks which we recognize as below any coal in the State; in this case the result is of general value in preventing further exploration below this depth. Only from the results of such deep drilling can the area of available coal in the State be exactly determined and the limits of the individual beds be defined, especially in those parts of the State where the coal beds are deep beneath the surface.
