PREFACE TO THE SECOND EDITION.



The favour with which the first edition of the present treatise
on Roasting of Ores was received by the mining public, and the
increased inquiries after a new edition, induced the author to write
the present book. During the long interval of ten years which
elapsed since the first edition, many improvements in the construction
of furnaces, as well as in the way of roasting, have been
introduced; this edition, therefore, has undergone many alterations,
and new cuts of furnaces, etc., have been, added.

San Francisco, Feb., 1880, t G. K,
