Book excerpt: Excerpt from The Non-Metallic Minerals: Their Occurrence and Uses The first edition of this work was little more than a reprint of a handbook of the collections in Applied Geology in the U. S. National Museum. An attempt was there made, for the first time in America, to bring together widely scattered notes relating to many of the minor and little used minerals, it being felt that with the rapid development of the arts the time had come for a review, at least, of this branch of the mining industry, as well as a look into future possibilities, so far as the development of natural resources would permit. Since the work was written, much has been accomplished in the way of both study and exploitation, as will be evident to one who will peruse the voluminous publications of the U. S. Geological Survey and the columns of the trade and mining journals, and it is felt that the time has now arrived for putting the matter in a form more concise as well as more comprehensive. In doing this, the author has availed himself of the great mass of literature passing through his hands as Head Curator of the Department of Geology, as well as an experience of near thirty years in collecting, observing and arranging the materials under his care. He has drawn for information upon every available source, and has striven to give full credit therefor. The name Non-Metallic, as used, it may be well to state, relates to the uses to which the various substances are put rather than to their true mineral nature. Otherwise expressed, the materials here described are considered with reference to their uses other than as sources of metals.
