1917. "Mrs. Van H. Manning. U.S. Bureau of Mines. Mine rescue methods. There were 750,000 men employed in coal mining in 1915, and of this number 2,264 were killed -- 190 less than in 1914 and 521 less than in 1913. 'This is the most gratifying report the Bureau of Mines has been able to make since it was established,' says Van H. Manning, director of the bureau. 'It indicates very forcibly to me that "safety first" has come to stay in the coal-mining industry.' " Harris & Ewing Collection glass negative. View full size.
