Summary of students.-First class, 16; second class, 3; third class, 2; total, 21. Foundation.-This institution was founded in accordance with the will of Mr. Edwin A. Stevens, of Hoboken, who bequeathed for the purpose a large block of land in that city, and a sum amounting, at the discretion of the trustees, to $650,000.

Plan and buildings.-The Stevens Institute is especially a school of mechanical engineering; but the fact that chemistry, metallurgy, and mineralogy, as well as the whole science of machinery, so important to mining engineers of the present day, are taught here, and the magnificent completeness of the buildings and apparatus of instruction, justify me in including it in the present chapter. My principal object is to present a description of the building, which will be highly interesting and useful to those who have to deal with the arrangement of such institutions. The following description and plates are extracted from the New York Enginering and Mining Journal of April 16, 1872, and have been inserted at this place since this report was transmitted to Congress.

The building is situated in the pleasantest portion of the city, its windows commanding a beautiful view of the surrounding country, as well as of our harbor and bay, and the edifice itself presenting a fine appearance when viewed from the deck of the ferryboat as we cross the river to visit it. (Plate I.)

The building is very substantially built of blue trap-rock, with brown-stone trimmings, from designs by Upjohn. It extends from street to street, and has two wings in the rear. It is three stories in height, and has a dry and roomy basement. (Plate II.)

In the basement is a work-shop, occupying the whole of the right-hand wing, and containing tools for working in both wood and metal, together with the steam engine which is to drive them.

Here, also, are gas-holders for oxygen and hydrogen, and from them pipes are led to the several lecture-rooms, where the lecturers may have occasion to use the lime-light or the oxyhydrogen blow-pipe.

At the opposite end of the basement are the boilers for heating the building, and for supplying steam to the engines, and at this end are the furnaces for metallurgical work, and under the wing are the assay-room and the rooms of the janitor.

On the first floor, (Plate IV,) we find at the right a splendidly lighted, high and airy hall, fitted up as a physical laboratory, and stocked with numerous ingenious and delicate forms of apparatus, such as were made use of by Faraday in his splendid researches in electricity, by Regnault, and by Tyndal, and by Melloni in their investigations of the nature and laws of heat, and by other physicists in other almost equally classical labors.

In the large room at the rear of the main building, which is the public lecture-hall of the Institute, we find seats for six hundred persons. The stage is fitted with all needed appurtenances. A trap-door being raised, pipes are discovered bringing water and gas from the street-mains, oxygen and hydrogen from the tanks in the basement, and steam from the mair boilers. Heavy copper wires connect with the large electric battery, and these, as well as the oxygen and hydrogen pipes, are also led under the floor to the different points in the room, (marked O H in the plate,) where they may be required for the magic lantern, or for other purposes.

The large room at the extreme left, No. 3, in the main building, is the library and model-room. It is of the same size as the physical laboratory, and is also a beautifullyproportioned and well-lighted room. Here are kept the books which form the germ of what is intended to be a fine technical library, and the models and apparatus which are not needed in the lecture-rooms in illustration of the regular courses of instruction. This is also the reading-room, and the tables are furnished with a well-selected list of periodicals, some of which are contributed by the publishers. The room in the wing at the left is the chemical laboratory, which, although not lofty, is well ventilated, and well fitted up with the best of modern apparatus. The balance-room is immediately adjacent, and contains some fine apparatus.

The second floor (Plate V) is occupied by the several lecture-rooms. At the right is the lecture-room used by the president when it becomes necessary for him to take part in instructing advanced classes, and at other times in special researches.

The little room off the stair-landing is also used by the president, as a work-room. The lecture-room of the professor of physics is next to the preceding a pleasant, well-arranged room, fitted up with every imaginable convenience, including all that were noticed in the larger lecture-hall, and also a pneumatic trough, and a set of Bunsen air-pumps.

Immediately over the main entrance is a room containing the principal part of the optical collection of the Institute, which is said to be the finest in the world, and con
