Excerpt from Field Book of Practical Mineralogy: How to Examine, and Report on Mines, Designed for the Use of Prospectors, Mining Men, Engineers, and Others The publication of this little volume is the result of a long cherished plan, although not as complete in its discussion of the subject of ore deposits, the examination of mines, assaying, etc., as were the author's original intention, these omissions are thought to have been compensated for in part by giving more space to the subjects of determinative mineralogy and blow-pipe analysis. In the composition and compilation of the subject matter herein contained, all due precautions have been observed in order to render the information perfectly reliable and trustworthy, and to this end all descriptions of minerals appearing in the tables were carefully compared with those given in the following named standard works on the subject of mineralogy: System of Mineralogy, by E. S. Dana, Determinative Mineralogy and Blowpipe Analysis, by Brush & Penfield. Other valuable authorities consulted are: Ore Deposits, by J. A. Phillips, Ore Deposits of the United States and Canada, by J. F. Kemp, and A Manual of Practical Assaying, by H. V. F. Furman. The names of all authorities consulted are mentioned in the foot notes. Where inadvertently omissions have occurred and due credit has not been given, the author would esteem it a favor to have his attention called to the neglect. He would also be pleased to receive criticisms on the work so that he may be able to take advantage of them should a future edition be called for.
