Illustrations that accompany a report issued by the U.S. Bureau of Mines regarding a buried valley area (a deposit of clay, sand, and gravel) around the Susquehanna River in the anthracite region of Pennsylvania, near the city of Wilkes-Barre. Most of the images are cross sections of the area.

From Introduction and Summary: "However, with the completion and satisfactory performance of an experimental vertical slot oven of 500-pound capacity at the University of Illinois Geological Survey Laboratory, the opportunity to directly compare BM-AGA coke with coke made by two-sided heating became available and the necessary test apparatus was installed. This report compares the results obtained by the two methods."

Report discussing experiments done on expandable waxes of lignites to determine yields and properties from certain place in the United States.

From Summary and Conclusions: "This report deals with upgrading to metal-lurgical standards of large reserves of high-sulfur Pittsburgh coal remaining in southwestern Pennsylvania and northern West Virginia."

From Scope of Report: "In this report one major unwatering project was developed. Three pools that inundate considerable tonnages of anthracite reserves are close enough together to be unwatered by some centralized system. Three alternative plans were studied to estimate the cost of each."

From Introduction: "The purpose of this investigation was to separate and identify as many of the principal phenolic compounds produced by the mild hydrogenation of Pittsburgh-bed (Bruceton) coal as possible and to determine with the greatest possible accuracy the proportions in which they are present."

From Introduction and Summary: "This paper gives results of an investigation of the composition and carbonizing properties of coals from Pocahontas No.3 bed, Lake superior No.4 mine, McDowell County, W.Va.; Eagle bed, Cannelton No.3 mine, Fayette County, W.Va; and No.2 Gas bed, Cannelton No.100 mine, Kanawha County, W. Va."

Report issued by the U.S. Bureau of Mines regarding a buried valley area (a deposit of clay, sand, and gravel) around the Susquehanna River in the anthracite region of Pennsylvania, near the city of Wilkes-Barre. According the the introduction, "The purpose of this report is to furnish data on the buried valley of the Susquehanna River that will be useful in solving the anthracite mine-water problem" and "This report (a) discusses the physical characteristics and the influence of the buried valley of the Susquehanna River on anthracite mining in the Wyoming Valley area of the Northern field, (b) correlates pertinent data relating to the buried valley, (c) presents accurate contour maps showing the position of the top of solid rock underlying the water-soaked valley-fill deposits in the buried valley, and (d) presents cross sections at regular intervals across the buried valley showing the irregularities in trend and bottom as well as the thickness, configuration, and nature of the materials composing the water-bearing valley-fill deposits" (p. 3).

From Forward: "The value of this survey of the carbonizing properties of American coals by a standard method lies in the comparability of the results on different coals. It must recognized that no standard laboratory method of carbonization, even on a large unit, can yield results that exactly duplicate those obtained in ovens and retorts. The commercial results vary with the type of oven or retort. Allowance must be made for such differences in interpreting the BM-AGA test results in terms of commercial plants."
