7. Exploration.—To determine general character and extent of deposits in advance of development; methods and aims. 8. Development.—Blocking out of deposits to prove values of partly explored ground, and to prepare for further explorations. Exploitation.—Laying out work; winning of coal, ore, etc.; stoping, overhand and underhand; winzes and intermediate levels; economical handling of product. Methods to be employed under various conditions. Dislocations.—Faults, upthrows, downthrows, feeders, leaders, rolls, swells, etc. Means of overcoming difficulties. Dressing of Products.—Coal screening and washing; sampling and grading ore; assorting, crushing, spalling, cobbing, concentrating. Mining Machinery.—Elements of construction, designing of plant, combination of parts; setting, arranging, adjusting. Preservation and operation, general economy. Organization.—Economy of management. Secondary superintendence; division of labor and adjustment of responsibility. Prevention of accidents. Administration.—Review of principles. System of reports from subofficers, and tabulation of records. Accounts, forms, analyses, pay-rolls, cost sheets, etc. Letting and measuring contracts. Miscellaneous details. Engineering Geology.—Applications of geology to engineering and mining. Nature and distribution of deposits of economic value, as coal, water, metallic ores, etc.; advanced structural geology and lithology; discussion of principles underlying successful working of mines, placing of foundations, setting of machinery, and erection of structures in various situations. Relation of geological structure to drainage, economy of working, selection of points of attack, methods of exploration, etc.

APPARATUS.

The department has a valuable collection of models of mining and metallurgical machinery. The newly equipped laboratory now contains a very complete line of illustrative machinery, designed for practical use, and covering a wide range of metallurgical processes. The machines are operated by steam power, and include apparatus for crushing, screening, washing, concentrating, leaching, precipitating, and many other methods of ore treatment of the latest modern types. In the manipulation of these machines, and the tests made on a working scale, the student is afforded opportunity for practice illustrative of the class-room work. The plant consists of a Dodge ore-crusher, a pair of Cornish rolls, elevator with deflecting spouts, automatic sampler, re-
