From Summary: "This report covers the second in a series of five projects into which the Conowingo tunnel system has been divided for geographical and practical reasons. It outlines the construction work contemplated-to sink two shafts on the line of the main tunnel that are designated the Nos. 9A and 11 shafts, to turn off from the No. 9A shaft the Landsford and Lykens laterals, and to drive portions of the main tunnel."

From Scope of Report: "This report covers the following: (a) A brief description of the work contemplated under Project No. 3 as an integral part of the Conowingo tunnel system; (b) an economic discussion of the area affected; (c) the geology and hydrology of the Northern field, including the Wyoming Basin; (d) the basic problem, plans, and costs, and the construction schedule of the project; (e) an economic analysis and a justification for the project; (f) recommendations and cooperation of local interests; and (g) final conclusions."

From Introduction and Summary: "A large number of published papers contain petrographic information relating to the specific coals investigated; a classified list of these papers is included in the report (p.144). To fill the obvious need for a compilation of all available petrgraphic information, this report gives tabulated data of 217 samples of various American coals investigated in the Bureau of Mines Coal Petrography Laboratory."

From Summary: "This report presents data on the corrosive and erosive effects of acid mine waters in the anthracite region on metals and alloys for pumping equipment and drainage facilities necessary to remove or control this water. This report is based on field tests conducted cooperatively by the Armco Steel Corp. and the Federal Bureau of Mines from January 1953 to June 1954 to determine the most suitable materials for constructing pumping equipment designed to handle these acid mine waters."
