From Preface: "The purpose of such publication is to point out the laws and regulations best adapted to increase safety and efficiency in the mineral industry of the United States and to aid legislative bodies in framing uniform mining laws. The State of California, by reason of its historic interest in mining and by reason of its great extent of mineral land and its vast mineral deposits, has been selected for the first bulletin of the of the State series. This bulletin is submitted to the miners and operators and all persons interested in the mining exterprises in California and in those of other States in the hope that it will be accorded the same generous reception as was given Bulletin 94."

The references are arranged according to the subject classification on pages 3 to 11."

From Introduction: "This report of investigations carried on by the Bureau of Mines gives the methods used in mining and milling and indicates in some detail the conditions that affect the efficiency of those methods; it does not attempt to discuss the geology of the district, except incidentally, as this has been described in numerous reports by several geologists."

From Introduction: "The data reported in this bulletin are largely the result of experiments conducted by the Salt Lake City station of the Bureau of Mines in cooperation with the department of metallurgical research of the University of Utah. The work on the lead is the only one of the phases of the investigations carried on at that station during the years 1914 to 1916."
