Excerpt from Aids in Practical Geology While the size of the book has not been increased in this edition, alterations have been made in more than one hundred places, whereby, it is hoped, the fairly wide subject-matter has been brought up to date or more adequately set before the reader. The book has always aimed at aiding those who enquire into the materials and history of the earth's crust, for purposes of research or for any special enterprise. At the same time, the student is not likely to forget that practical geology is fundamentally to be followed in the open country and the open air, and that these "Aids" are intended to help towards the determination of what has been personally gathered from the mountain-side or in the plain. For those who take pleasure in learning from the earth around them, a smaller volume has been written, "Open-Air Studios in Geology," in which special appeal is made to the rock-masses as we meet them in the field. But all the wide developments of geology must rest on patient determinative work; and the invention of a new piece of apparatus for the laboratory, or the correct appreciation of a fossil, may open up the clue to some long-sought secret of the earth. While certain modern restrictions in nomenclature have been introduced, which undoubtedly tend towards exactitude, the limits of the names of rocks and fossil genera have been kept as wide as possible.

Excerpt from Aids to Identification of Geological Formations By long experience many drillers learn to distinguish, generally quite correctly, the three principal classes of sediments in which most of their work is done, such as shale or clay, sandstone and limestone. The most experienced drillers in any locality have, also, expert knowledge of what we may call the "key rocks" of the field in which they work. They know the rocks that determine the depth at which casing is to be set, or the depth at which the tests for oil or gas must be made. This knowledge of rocks is mostly taught from mouth to mouth, by the head driller to his helpers, entirely without any other guidance than the limited experience of each driller. No aid, so far as I know, has ever been prepared by geologists to help drillers in procuring the information both are eagerly seeking. With the extension of drilling operations to regions of widely different geological formations and conditions, it has become a matter of some urgency that drillers' logs be made with greater accuracy and uniformity than before. The only way to encourage improvement in this direction is to place in the hands of the men who make the "logs," what aid they need. By the use of a few very simple devices, available to all, great improvements in results can be attained without the least loss of time. The present paper is an attempt to present some information, in compact form, that will aid practical and intelligent men to correctly identify materials explored in drilling for oil, gas, or water. It will be found that much of the information here set forth consists of elementary methods and facts drawn from mineralogy and geology. Most drillers are eager to acquire all knowledge they can in these sciences. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
