From Introduction: "This bibliography, which is intended to be the first of a yearly series, has been compiled by the petroleum division of the Bureau of Mines with a view to satisfying this need. The references include only the more noteworthy writings that appeared during the year 1915 in both the United States and foreign countries. The references are arranged according to the subject classification on pages 3 to 11."

Report discussing the development of gold dredging in the United States, the essential features of present-day dredges, the facts that determine whether a placer deposit can be profitably dredged, and the approved methods of prospecting placer ground and of operating dredges. Intended for designers and builders of dredges, mining engineers, and persons who may contemplate investing capital in placer-mining ventures.

From Introduction: "The Bureau of Mines has been conducting investigations with the view of determining the types of containers best adapted to the storage of oil. These investigations have shown that tanks composed wholly of steel give the best results. Practically all such containers in use at present have wooden roofs and this type of construction is here described, although it is the belief of the writer that concrete roofs would be far more satisfactory in every way, and that the difference in cost between a concrete and a wooden roof would, as a rule, in a few year's time, be offset by a saving oil and in cost of repairs and renewals."
