PLANS OF LINCOLN GRAMMAR SCHOOL-HOUSE, Boston.

THE following description of the Lincoln Grammar School-House is taken from the annual report of the school committee for 1859 :

"In the design of the Lincoln School-House, which is located on Broadway, near K st., South Boston, it was the intention of the accomplished architect, J. F. G. Bryant, Esq., to combine all the advantages of the interior plan of the best buildings, with an effective and tasteful exterior, without any material increase of expense.

"There seems to be no good reason for perpetuating that baldness and almost primitive simplicity of style which have characterized most of the school edifices of the city. It can scarcely be deemed too much to demand, that the building which is the daily resort of our children and youth, and in which their mental and moral faculties are to be trained and unfolded, should be designed with careful reference to the rules of proportion, and even, in no small degree, of beauty. Certainly it would be well to keep this object in view, so far as it is consistent with a wise and proper economy. Harmony of style, and propriety and elegance of detail, will never be without their refining influences upon the mind of the pupil.

"The following mechanical description, extracted from the 'specifications' of the architect, will illustrate the interior conveniences of the building and its adjuncts, as well as the manner of construction and the formation of the exterior."

The building is a" parallelogram "in outline of ground plan, measuring ninety-three and four-twelfths feet in length, and sixty-one and two-twelfths feet in width, outside of its base or underpinning course, at the ground or sidewalk level in front of the building. It is four finished stories in hight, with an "unfinished" cellar story over the whole area, which is partially above and partially beneath ground. The cellar is nine feet high. The first, second, and third stories, respectively, twelve and one-half feet high, and the fourth story fifteen feet high. The top of the gutter of the outside walls is located four and two-twelfths feet above the ceiling of the fourth story, which ceiling is formed immediately upon the undersides of the tie-beams of the roof framing, or attic flooring. The roof is "hipped " from each of the four corners of the building, and is made a "Mansard," with curved sides and a "flat" top; the hight above the top of cornice to the top of the curve of the roof is fourteen feet; its "flat" is located in the center of the length and width thereof, and it measures eighty-six and one-half feet in length, and fifty-one and one-half feet in width, and has a pitch over its surface of one and one-half inches to a foot. The four corners of the roof are formed as projections; the spaces between the projections over all four sides of the building are recessed to intersect with recesses in the faces of the four exterior walls; said projections are hipped over the inner corner of each, in imitation of the hip over the outer corner thereof-being the corner hips of the building. The recesses in the faces of the four exterior walls aforesaid are located in the center of the length of each wall, and reach the whole hight of said walls, to meet the roof recesses abovenamed. The recesses in the front and rear end walls each measure twenty-one and five-twelfths feet in width, and those in the two side walls twenty-three feet in width. Besides the four recesses aforesaid, there are recesses in the faces of the projections, or corners, which are formed to each exterior wall, beneath the roof projections; these recesses reach from the ground level up to the top of the third story, where they are formed with semicircular heads. The recesses in the corner projections of the front and rear ends of the house measure eleven feet and three and one-half inches wide, and four inches deep, and are single recesses; and the recesses in the corner projections of the two side walls of the house are eleven feet and three and one-half inches wide, and four inches deep, and are double recesses, with a dividing pilaster located in the center of the width of each of the same, and double semicircular heads to each recess,
