The floor joist G is supported on a ledgerboard H, or it may rest directly on the plate A. The piece of stud-ding I is merely a furring studto form the wall of the atticroom. It may be omitted en-tirely if desired, or if the atticsare to be unfinished. The ceil-ing joist K may be supportedon a ledger board as shown, ormay be simply spiked to thestudding I or to the upright studding I may rest directlyon the floor joist G with a solepiece L at the bottom as plate C should be of a goodsize, at least 4X6 inches, and should not be placed more than 2 or 3feet above the ceiling joists K. The ceiling joists act as ties acrossthe building and prevent the plates C from spreading apart, as they receive the thrust from therafters D. For this reasonit is better to have the ceil-ing joist K fastened to theupright B rather than to thefurring stud /. Dormer
