ROSS'S IMPROVED ADJUSTABLE STAND,

Which will be found very convenient for the exhibition of Philbrick's Boston Primary School Tablets, or small Black-boards, in the School-room. This movable stand enables the Teacher to place the Tablet where it can be seen to the best advantage by the class. The ledges on which the Tablet rests may be raised or lowered at pleasure. The above stand is introduced and in extensive use in the Boston Primary Schools.

PLANS OF PRESCOTT GRAMMAR SCHOOL-HOUSE, BOSTON.

The following description of the Prescott Grammar School-house, prepared by Hon. John D. Philbrick, Superintendent of Public Schools, is taken from the Annual Report of the School Committee for 1865:This noble edifice, which is well represented in the accompanying perspective view, is located in the easterly part of East Boston, about two miles from the City Hall. It stands near the centre of a lot which is just two hundred feet square, and is bounded on three sides by wide streets. It has a frontage of one hundred and thirty-eight feet on Prescott Street, and sixty-eight feet on Bennington and Saratoga Streets, respectively. It is three stories high, exclusive of the basement and attic. From an inspection of the accompanying cuts it will be seen that the ground plan of the building consists of five parts, namely, a central portion thirty-five feet by sixty, two wings, each thirty-one feet by sixty-eight; and two entrance halls, connecting the wings with the central portion, cach twenty-one feet by fifty-six. There are four entrances, one in the front and one in the rear of each entrance hall, the two principal or front entrances being on Prescott Street. In each of the entrance halls there are two well-lighted staircases, leading from the first to the second story, and one leading from the second to the third story. The building contains sixteen school-rooms, of the same size, namely, twenty-eight feet by thirty-two. Six of these rooms are on the first floor, six on the second, and four on the third. It will be seen, on examining the plans, that each of the twelve rooms which are in the wings has a spacious and well-lighted clothes-closet attached, and that each of the four rooms in the central portion has two such closets. Each of these closets communicates both with its adjacent schoolroom and entrance hall, and serves as a passage-way for the pupils in going in and out of their rooms These closets are only half a story in height, there being above each an apartment of the same size and height, which is entered from a middle landing of a staircase. The latter are designed for dressing-rooms and water-closets for teachers, receptacles for books, school apparatus, etc. The schoolrooms of the first and second stories are twelve and a half feet high in the clear; and those of the third story fourteen feet. The whole of the third story of the central portion, with a part of the space over each entrance hall, is devoted to an assembly and exhibition hall, which is sixty-five feet long, fifty-seven feet wide, and eighteen feet high. This is the largest and best hall for school purposes in the city. Its symmetrical and convenient arrangement is shown in plan No. 3. The basement, which is well paved with bricks, is ten feet high, and its extensive area, with the exception of the space occupied by the heating apparatus, is available as play-rooms for the pupils in stormy weather. The floors of the entrance halls are rendered fire-proof by means of iron beams supporting brick arches, on which are laid North River flagging stones. The other floors are laid with scantlings 14 by 14 inches, blind-nailed, forming a solid and smooth surface, — such as is needed for receiving the screws which secure the seats and desks, -without any wide cracks at the joints. All the windows are fitted with inside folding blinds, and those on the northerly and westerly sides have double sashes. The halls in each story are furnished with sinks, which are supplied with water from the Cochituate pipes. All the rooms are brought into communication with the master's room by means of speaking tubes and bells. Each of the school-rooms is furnished with fifty-six single desks and chairs of the most approved
