These furringstrips are either notched over the beams or dropped belowthem by the insertion of shps to bring them in hne. On these furring strips the laths are then nailed, and if,on any side of the room, there is no beam in the anglebetween the side wall and the ceiling to which a furringstrip can be nailed to secure a firm corner, pieces must benailed on the plate of the partition to receive the ends of thestrips, in the same manner as nailing places were establishedat ec and cd, in Figs. 37 and 38, to receive the ends of thelath. When a ceiling is cross-furred, it is more rigid; theplaster is less liable to crack by the vibration of the floor-beams, and, being generally of less width than the thicknessof the joists, a better rivet is secured for the Fig. 39. 127. Tru8so<l partitions are sometimes necessary wherethere is no supporting partition in the story below, or wherea partition has a number of doors or other openings through CARPENTRY. 63 it so weakening it that it cannot safely carry the requiredweight to be imposed upon it. Fig. 39 shows a trussed par-tition with a door 4 ft, 6 in. X 7 ft. 6 in. in the center of sill a and the plate b are made 5 in. x 7 in. The studs cat each side of the door are 3 in, X 5 in., and the upright wallmembers g are 6 in. X 5 in. The height of the door is limitedby the 3x5 timber e, from the ends of which the 4x5braces d extend to the ends of the sill a, where they are let inat/ to secure them from slipping. A truss cqpr is therebyframed, around the members of which the 2x5 studs/arecut. The entire weight of this partition, together with anysuperimposed load, will come upon the points c and r, whereample support must be provided t
