Spectroscopy of Uranyl Salts in the Solid State
From Introduction: "The interpretation of the fluorescence and absorption spectrum of the uranyl ion, indicated in this introduction, is based on the spectroscopic work of Nichols, Howes and co-workers (1914-1919), Dieke and van Heel (1925), Moerman and Kraak (1939), and Freymann and co-workers (1946-1948); on infrared studies (cf., Section 3 below) and Raman spectra; but most of all, on the work of Dieke, Duncan, and co-workers, carried out in 1943-1944 under the Manhattan District program. In the present chapter we will review briefly the earlier investigations in the field of uranyl salt and spectroscopy and give a somewhat more detailed summary of the results of Nichols and Howes and, particularly, of Dieke and co-workers."

Visual-Arc Spectroscopic Analysis
From Summary and Conclusions: "The methods described in parts I and II are used largely to detect the cationic constituents of minerals and boiler-scale materials by means of atomic or line spectra. Part III gives results of an investigation of the molecular or band spectra of the visible region made to determine whether any additional anions could be detected by this means. Part IV lists equipment for visual spectroscopic analysis that is available commercially."

Mine Pumping Plants: Anthracite Region of Pennsylvania
From Summary: "To obtain a reliable picture of the anthracite-mine-water problem and to solve that problem, it is necessary to have factual data on the volume and the quality and character of mine water handled by pumping plants in the anthracite region, as well as kinds of pumps utilized and problems concerning their operation. The main conclusion that be drawn from an investigation of drainage practices in the anthracite region is that, although efficient pumping layouts, tunnels for draining active mines, and large-scale surface-drainage facilities for keeping water out of mines are in use, the anthracite industry still is threatened with curtailment, to a major degree, and premature extinction because of the encroachment of water, unless remedial action is undertaken in the vary near future by all interests concerned."
