Plates bright and crisp. Scarce. From the original review in Nature magazine: "Mr. Riemer is one of the leading German authorities on sinking, and a translation of his valuable treatise forms an addition to English technical literature that is specially welcome in view of the fact that shaft sinking, the most complicated of all mining problems, is necessarily dealt with in a brief manner in the standard works on coal-mining. The volume is confined to a description of means that have to be resorted to when ordinary methods of sinking cannot be applied on account of excessive influx of water, the means described being shaft sinking by hand, boring shafts, the freezing method of sinking, and the sinking-drum method."
