that a special appropriation of eight thousand three hundred dollars was made last June for this purpose, which will enable us to add some new apparatus to the laboratory, though much more is urgently needed.

More room is also needed for new apparatus, to relieve present crowding, to furnish room for students to carry on thesis work on apparatus brought in from outside, to provide storage room for large and miscellaneous apparatus to be used on thesis work conducted outside, and to provide room for stripping machines for the purposes of Machine Drawing.

DEPARTMENT OF MINING ENGINEERING and
METALLURGY.

The John Cummings Laboratories of Mining Engineering and Metallurgy are constantly being developed to bring the student into intimate contact with the latest ideas in ore-dressing and metallurgy. In the Ore-dressing Laboratory a new jig, of the pattern approved in the Michigan copper concentrating works, is being constructed. In addition the Harz jig has received new automatic discharges, a new canvas table has just been supplied, and the Wetherill magnet is being improved.

In the furnace room a hydraulic elevator has been installed to raise materials from the bins to the main floor of the laboratory. An iron structure to handle the Devereux slag-pots has replaced the wooden one formerly used. Part of the floor has been cemented to facilitate the handling of pots filled with melted slag. In order to save time in the repair of the test used for refining copper, special forms of brick are now used, a plan which does away with the cutting of tiles to suitable sizes.

In the Metallographical Laboratory the addition of a gas furnace, an automatic recording pyrometer, and a dark room are contemplated for work on metals and alloys.

The office and library had become so crowded that relief was imperative. Space was obtained by utilizing room reserved

for the museum, and distributing the specimens. In the former museum the floor, which was five feet eleven inches from the basement, was raised two feet four inches, dividing the available space into a lower room six feet eleven inches high and an upper room nine feet six inches high. In the lower room, lighted and ventilated electrically, all the apparatus of the Metallographical Laboratory and eight show-cases of specimens are placed. In the upper room is the library of the Department. Here are the office of Professor Hofman and the desks of his three assistants. The small cases in the old library are filled with collections representing mining districts. This room serves now as office for three assistants. The original office is occupied by Professors Richards and Locke.

Professor Richards has recently presented to the library of the Department from his own library one hundred and thirtytwo books and pamphlets which the former did not contain.

In the Assaying Laboratory all the balances have been overhauled and put in thorough repair. The assistants' office, formerly overcrowded, has been relieved by the library changes.

Among changes in the work of instruction may be mentioned the fact that the exercise in Laboratory Reports has been enlarged by requiring the students to make written reports on all the work that they have done in the three sections into which they are divided.

Memoirs, which used to be given once a week during both terms of the fourth year, are now given, through force of circumstances, twice a week during the second term only. The result will be watched with interest.

The number of students is not quite so large as last year, owing to the departure of the phenomenal class of 1906. The numbers in the fourth year, the third year, and the second year are respectively twenty-eight, thirty, and thirty-six.

Charles E. Locke has been promoted from Instructor to Assistant Professor of Mining Engineering and Metallurgy. Carle R. Hayward, teacher at Bellows Academy, Fairfax, Vt., has been appointed Instructor in Metallurgy, in place of

Robert Faulkner, who has gone to the National Tube Works, McKeesport, Pa. Arthur P. Watt has been appointed Assistant in place of George A. Barnaby, who is surveying in Peabody, Mass. John A. Root has been appointed Assistant in place of Moses Brown, Jr., who is surveying in the copper country at Lake Superior.

Last year Professor Sauveur resigned his position as lecturer and demonstrator in Metallography. The subject is now in charge of Professor Hofman, who gives the lectures and con- . ducts the laboratory exercises.

Professor Richards is engaged in writing an appendix to his work on Ore-dressing, and Professor Hofman is at work on a treatise on Metallurgy. Professor Richards has also been acting in the capacity of consulting engineer for works in Pennsylvania, Virginia, Missouri, Colorado, and Oregon. He is at present investigating the rate of settling of mineral grains in water, and also the laws governing the design of hydraulic classifiers, and of the Wilfley concentrating table.

During the summer Professor Lodge attended the meeting of the American Institute of Mining Engineers, which was held jointly with the British Iron and Steel Institute in England. Professor Locke made an extensive trip among the mines of New England and Eastern Canada.

The Summer School, in charge of Professors Richards and Locke, and joined later by Professor Hofman, was held in New York, Ohio, Minnesota, Michigan, and Ontario. It included, besides the instructing staff, one graduate, three fourth-year men, two third-year, and two secondyear men. Among the industries visited at Niagara were the Acheson Graphite Company, the Carborundum Company, the Niagara Falls Power Company, and the Hydraulic Power Manufacturing Company. A most enjoyable journey from Ashtabula to Duluth was made in the ore steamer "John J. Allbright." In the Mesabi region of Minnesota, at Hibbing, the Burt Poole mine and the Mahoning mine were visited. These are monster open pit mines of iron ore. At

Duluth the party inspected the great ore docks. At Ironwood, Michigan, the Newport deep mine of iron ore was studied inside and out, and the surface plant of the Norrie mine. At Iron Mountain the Chapin deep mine of iron ore was studied and also the power plant and compressed air pipe line. In the copper country the Champion and Trimountain mills were studied. The party went into the Baltic mine and made a study of it. They visited the Osceola and Quincy mills, and the surface plants of the Calumet and Hecla and the Tamarack mines, the Michigan smelter, and the Calumet and Hecla smelter. Professor Locke also made a visit to the Victoria hydraulic power plant. The party next took the passenger steamer to Sault Ste. Marie, where they studied the blast furnaces, the steel plant, the electric iron furnace, and the charcoal plant of the Algoma Steel Company. The next move was to Sudbury, Ontario, where were visited the Crean Hill mine and the Creighton mines of the Canadian Copper Company and the Victoria mine of the Mond Nickel Company, together with the smelting works of both these companies.

The Department desires to record here its thanks for the generous and cordial welcome given to the students of the Summer School by the managers of the above-mentioned companies and firms, and for the many courtesies extended by former graduates and others.

Several undergraduates were employed in mines and at furnaces during the summer vacation. One went to Colorado, seven to Cape Breton, three to Montana, two to Missouri, two to New York, three to Utah, and one to Alaska.

The demand for graduates is still active. The Department could have placed more than the large number graduating in 1906. This is especially true of places in iron and steel metallurgy.

DEPARTMENT OF ARCHITECTURE.

This year the new Course Scheme made possible by the increased entrance requirements in Modern Languages is for the first time in complete operation. The two hundred and seventy hours which became available for additional general and professional work have opened the way for many modifications and improvements in the courses given by the Department, that promise well in the direction of greater efficiency in methods of teaching, and a general broadening of the Course. A generous proportion of the added time has been devoted to an increase in the structural subjects taught in Options I. and II. These changes have, on the other hand, very largely extended the labors of Professor Lawrence, who had all that he ought to carry before. As these hours represent class work, and as the instruction is practically all with individual students, each of whom may be working on a different problem in the same class, it is evident that the demand upon his time has been so materially increased that he should have aid to help him in routine work, and so give him the opportunity to do full justice in the way of extension or improvement to the courses of instruction under his charge. Undoubtedly, an assistant could be secured from the graduating class to serve next year, and I hope this will be allowed.

More applications come for graduates from Option II. than it is possible to meet, and the reputations of those offering these positions are sufficient proofs of the high consideration in which these graduates are held. This standard we are bound to maintain.

The good results that have attended the union of third and fourth-year students in a common drawing-room have made it highly desirable that the second-year students should have part in the same arrangement. Unfortunately, our limited floor area on a single story makes this impossible of accomplish
