Excerpt from A Text-Book of Ore and Stone MiningThe object of my text-book is to assist students in acquiring a knowledge of the art of mining. Books and lectures are not intended to take the place of practical teaching at mines, but they render the training more thorough and complete in many ways: they serve to explain the principles of the art, to solve difficulties which perplex the beginner, to suggest matters which he should observe, to tell him of things beyond his ken, and to supply him with a system for arranging his ideas methodically.It will be seen by my numerous references that I have not hesitated to avail myself of very varied sources of informa tion, and that I have taken care to avoid dwelling too much upon English examples.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
