The last Legislature rnade appropiiatiüns for an additioii to the chemical kiboratory of tlie Michigan Agr i cultural College, and for the erection of a building for library and museum. Last Spring the state board of agriculture advcrtized for plans, and accepted those of Charles H. Marsh, of Detroit, for the library and museum building, and let contracts to Fuller & Wheeler, of Lansing, for the congtruction of the same. The Board of Agriculture met last Tuesday to inspeet and accept the library and museum building. A reporter of the Lansing liepublican says : The library and museum is located on the level plat about 20 rods east of the main building, and about 15 rods northeast of the new boarding hall, The building is the shape of a T, the one arm running north and south being 37 by 82 feet, and the other one 42 by 62 feefc, running east and west. It consists of a basement 8 feet deep, a main story 16 feet in height, and a second story 14 feet in height, and over the main entrance a tower, the extreme point of which is 92 feet from the ground. The builáing is of red brick, with water tables, window and door caps, and sills and trimmings of eut stone. The main entrance is on tke west side, by doublé doors, over which is a stone cap bearing the inscription, in old Gothic letters "library and museum." Entering here one finds himself in a vestibule, 6J by 13 fet in size, communicating with the interior by doublé doors. On either side of these doors is a window of cathedral glass, 2 by 8 feet in size, set in small squares, and over the doors a large transom. Beyond these doors is the main hall, 13 feet wide by 22 feet in length, on the north side of which rises a wide staircase, leading to the second story. The floor of the hall is tiled with white marble, bordered and dotted with red slate. The reporter proceeds to describe two reoeption rooms, 16 by 17, connected by sliding doors, the office of the private secretary, 17 by 20, and then describes the library room: Opening from the east end of the main corridor, through large doublé doors, is the library room, 40 feet in width by 50 feet in length, occupying nearly the entire main floor of the east wing. It is lighted from north and south, by five large Windows on a side. About 12 feet from the wall, on each side, and running east and west, are two rows of iron columns, eight in all, which support the floor of the second story. From each of these, columns book shelves will be run to the wall, similar to those in the state library, and forming well-lighted alcoves between. At the extreme east end is a small room, 11 by 18 feet, connected with the library by an archway, and designed for the assistant librarian. The spaces on the second floor are designed for Prof. Cook's classes, his private room, laboratory, packing room, etc. The Republican adds: The entire work on this building challenges comparison with anything of a similar character in the northwest, and would alone establish the reputation of Messrs. F ulier & Wheeler as builders, if they could point to nothing else, which is fortunately not the case. As sub-contractor, Charles M. Chittenden of this city superintended the entire masón and bricK work from cellar to roof, and to say it is a good ]ob does not cover the grouud. It is a monument of neatness, strength and skill, and what might be expected i'rom the man who supervised the masons on the state capitol. TAE LABORATOEY ADDITION, attached to the south end of the old building is of the same pattern, constructed of Milwaukee brick, and consists of a basement 10 f eet deep and a main story 16 feet in height. It ia attached as an L, and is 41 by 7J. feet in size. It is divided into a lecture room on the east, with a bowl-shaped floor, 38 by 40 feet in size. On the west is the private study of the professor of chemistry and an instrument room. A 75-barrel, iron water tank is connected with the building, and the entrance is by an ornamental porch on the south side.
