![Under the windows the wainscot should be the whole height from floor to window sill—four feet. For very cheap work, the panels may be § inch boards nailed to the wall, and the framing, or “stiles” also of § inch pieces neatly fitted and nailed at top. Fig. 31.—Panelled Wainscoting and Section. (b) Wainscoting should be finished with a bevel or quarter round, which on the side walls may form a continuation of the stoolcap moulding of the windows. Under the blackboards it is common to finish with a moulding either shaped out of the solid into a trough on the top, or supporting a separate one, which may be simply a strip of half-inch board, inclined towards the blackboard (as in fig. 33). This is to catch chalk dust and hold crayons and rubbers. (c) Hallways and vestibules may with advantage also be wainscoted in the same simple manner, three or four feet high. Door and window architraves [should be] very simple. 102. Blackboards. The Regulations (No. 22) direct that— Fig. 33.-Chalk Tray Mould¬ ing, No. 2. “ There should be one blackboard at least four feet wide, extending across the whole room in rear of the teacher’s desk, with its lower edge not more than two and a half feet Chalk above the floor or platform, and, when possible, there should be an additional blackboard on each side of the room. At the lower edge of O each blackboard there should be a shelf or trough five inches wide for o holding crayons and brushes.” * Fig. 32. Tray Mould¬ ing, No. 1. * The following directions for making a blackboard [appended to the regulation] may be found useful:— (а) If the walls are brick the plaster should be laid upon the brick and not upon the laths as elsewhere ; if frame, the part to be used for a blackboard should be lined with boards, and the laths for holding the plaster nailed firmly on the boards. (б) The plaster for the blackboard should be composed largely of plaster of Paris. (c) Before and after having received the first coat of color it should be thoroughly polished with fine sand paper. (d) The coloring matter should be laid on with a wide, flat varnish brush. (e) The liquid coloring should be made as follows:—Dissolve gum shellac in alcohol, four ounces to the quart; the alcohol should be 95 per cent. strong ; the dissolving process will require at least twelve hours.
