Excerpt from The Technology of Marble Quarrying The Bureau of Mines was fortunate in procuring for its share of the work the services of Mr. Oliver Bowles who had had experience in examining and describing quarries in Minnesota. During 1914 Mr. Bowles personally visited 64 active marble quarries. Through the cooperation of quarry owners numerous representative samples of the marbles of the United States were obtained and shipped to the Bureau of Standards for testing. The results of these tests will appear in due time. The description of the investigations of quarry methods and the general technology of marble are published herewith.
