Set of Twelve Diagrams illustrating the Principles of Mining

Abstract

ARRANGED in accordance with the syllabus of the Department of Science and Art, this admirable set of diagrams will prove of great value to teachers of evening classes in the principles of mining, for there can be no doubt that hitherto the want of suitable wall diagrams has proved a serious obstacle in the way of efficient instruction in this important subject. The diagrams measure 30 by 40 inches, and the subjects dealt with are: (1) the geology of the British Isles, (2) the occurrence of coal and ore deposits, (3 and 4) boring plant, (5) methods of sinking through watery strata, (6, 7, and 8) methods of supporting excavations and the construction of dams, (9, 10, and 11) methods of working, and (12) pumps and ore dressing. The illustrations have been selected with great care from standard authorities, due acknowledgment of the source being made in each case. The only fault that can be found with the diagrams is, that the authors have covered so wide a field that it has been necessary in some cases for them to crowd together into one diagram too many drawings. The best of the series are the remarkably bold and effective diagrams illustrating methods of working. The least satisfactory are the perspective views of machinery and of timbering. Plans and sections would have been better.
