Excerpt from The Mount Lyell Mining Field, Tasmania: With Some Account of the Geology of Other Pyritic Ore Bodies Among the necessary consequences of successful mining is the destruction of the evidence as to the origin and relations of the ore deposits. Unless the mines are described, while they are being worked, all chance of accurate knowledge of their geology is lost; and clues, by which a later generation of miners might follow the lode tracks to greater depths, are destroyed for ever. I accordingly trust that the Geological School of the Melbourne University will take some share in the descri ption of those Australian mining fields which have not yet been monographed by the State Surveys; and I hope that the following account of the Mount Lyell Field will be only the first of a series from the Geological School of the University. Recognition of the importance of geology, as a guide to mining, seems to me to be rapidly growing in Australia. It is becoming more widely understood that mining geology is not a batch of Speculative hypotheses, but a collection of verified and systematically arranged facts, as to the relations of ore deposits. This branch of geology accordingly enables miners to distinguish true from false analogies between different mining fields, and thus to save deplorable waste of money in development of the mines. In addition to the men, to whom I have expressed my indebtedness on page 3, I have to thank Mr. A. S. Kenyon for his careful help in passing this book through the press.
