    Mineral Industry of Alaska in 1928

    MINERAL RESOURCES OF ALASKA, 1928 MINERAL INDUSTRY OF ALASKA IN 1928 By PHILIP S. SMITH 1 INTRODUCTION For many years the mineral industry has been one of the main contributors to. the development of Alaska, if not the main industry. To assist in fostering this industry the Federal Government through the Geological Survey has for 30 years paid considerable attention to the problems relating to the industry and, by means of its studies of the distribution, character, origin, and extent of ore deposits, has kept those interested in mining developments informed of the facts of significance to the prospector, the miner, or the business man. One of the phases of these investigations that has obvious value is an annual record of the kinds and quantity of mineral produced, as such a record furnishes measures of the size and trend of the industry. It is to supply this information that the Geological Sur- vey collects annually records of the production of all mineral com- modities and makes these records available through annual reports, of which this one is the twenty-fifth. 2 The collection of the data necessary for these annual statements is by no means a simple matter, because the great size of the Terri­ tory, the diversity of its mineral products, and the large numbers but small size of many of the enterprises make it impracticable to gather all the desired information at first hand. The information must therefore be obtained from many sources, which necessarily vary in reliability and completeness. Among the most reliable sources are the field engineers, geologists, and topographers of the Geological Survey engaged in Alaskan surveys, who acquire much accurate information regarding the mineral production of the regions 1 The statistics in this chapter have been compiled largely by Miss L.
