From Introduction: "The purpose of this report is to furnish factual data on barrier pillars that enter into the water problem of the Wyoming Basin; these data will, in turn, be helpful in solving the anthracite-mine-water problem of the Northern field."

From Scope of Report: "The report covers the following: (a) A brief description of the proposed Conowingo tunnel system, which will drain the anthracite mines of Pennsylvania into the Susquehanna River at Conowingo. Md.; (b) economic development of the Northern field and the improvements desired; (c) geology and hydrology of the Northern field; (d) the basic problem, plans, and costs of Project No.1 (Lackawanna) ; (e) economic analysis and justification of the project; and (f) final recommendations, including financing and cooperation of local interests."

Scope of Report: "This report summarizes the engineering study conducted during 1953 by engineers of the Federal Bureau of Mines on seepage of surface water into mine workings underlying the Southern field drainage area."

From Introduction and Summary: "Reports from operating companies showed that 25,715 men worked at coke ovens in 1951, about 6 percent more than were employed in 1950 and, except in 1943, the largest work force since 1930, when 28,139 men were employed. The work time for all employees was 70,190,493 man-hours. The returns indicated an average of 344 work days per man as compared with 341 days in the previous year. Accidents at the ovens resulted in the death of 10 and injury to 768 workers, both of these figures representing fewer injuries than in 1950."
