Metallurgy of Gold

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. When gold was first discovered in California, the knowledge of metallurgy and mining in their several branches, among the people of the United States, was very rudimentary. But with that discovery a new era began over the vast expanse of territory extending from the Atlantic to the Pacific. The citizens of the great Republic awoke to the fact that in their mountain ranges were minerals of all kinds, representing enormous wealth, which could not be secured without extended knowledge of the requisite appliances. These were rapidly introduced in all branches of metallurgy, and in the advances thus made the treatment of gold-bearing ores has kept pace with the improvements effected in other branches of the science. Brilliant results have been achieved in the last twenty years, and I shall rejoice if the present work assists in extending knowledge of the subject and in further stimulating progress in invention and the development of gold mining.
