B. BURR PUBLISHING CO. 1877. PREFACE. The chief intent of this work is the plain, sufficient, and entertaining description of the marvelous lives not only of miners, but of all whose lot or choice it is to “delve and dare” underground. That its object is secured, the author is flatteringly assured by acknowledged critics,—travelers and book-men themselves, like the writer, most of them. The narratives of the book are not merely dry relations of scientific facts freighted with unnecessary technical terms, as might possibly be suspected from a cursory glance at the list of the topics treated, but statements of most important and curious deeds, and descriptions of hidden localities and lives, interspersed with lively anecdote and “incidents with souls in them,” it is believed, and the greater part herein for the first time given to the public. The table of contents will suffice to show how wide and varied has been the author’s scope of observation and comment, covering all the most important parts of the globe.
