9. Assaying.—For students in mining engineering. The course in assaying consists of instruction by lectures and from text books upon the ores, fuels, fluxes, furnaces, reagents, and chargers used in the fire assay of gold, silver, and lead ores. The laboratory practice includes daily use of the crucible and muffle furnaces and the manipulations connected with fire assaying. The rapid wet assay of copper and zinc ores is given in close connection with the course in fire assaying. Same as assaying in Chemistry 3. Winter term, 10 hours a week. Required: Chemistry, 1, 6; Mining Engineering, 1. 10. Metallurgy.—Especial attention is given to the effect of impurities in ores upon metallurgical processes and finished products. Fuels, refractory materials, and fluxes are described and their value and application explained. The known chemical reactions are expressed in equations; ore mixtures are calculated from analyses and experiments; and the size, construction, and working of furnaces are treated in accordance with modern practice. A series of models of furnaces and specimens of furnace material and products are used in illustration. The University is sufficiently near large and well conducted works smelting and refining iron, zinc, copper, silver, and lead for excursions to be made to them during the course. Instruction is given from text books when possible, but great freedom in choosing material from later publications and from the present practice of actual plants is used in the supplementary lectures. Greenwood's Steel and Iron; Peter's Modern American Methods of Copper Smelting. Spring term, 5 hours a week. Professor PAKE. Required: Chemistry, 1, 6; Physics, 1.

MINERALOGY.

1. Mineralogy.—The first three weeks are devoted to crystallography, with recitations and laboratory practice upon models of crystal forms. In the determination of minerals students work upon sets of unlabeled hand specimens. Familiarity with species and skill in applying the best and quickest methods of determination are attained by constant practice on a large number of specimens; and the lectures and other instruction acquaint students with the chemical composition and the schemes of classification. Especial attention is given to ores and rockforming minerals. The lectures are extended to cover the whole
