Each 2 by 4 stud, when braced by the siding, will be capa- ble of practically sustaining 12 tons. The strip on which the joists rest will sustain nearly three tons by each stud, so that supposing the floor joists to bo equal in strength with the bearings, the floor of a balloon frame building 16 by 24, with 2 by 4 studs, will practically sustain an equally distributed weight of 100 tons, weight of floor included. The floor joists in a balloon frame may be as heavy as desirable, equal witfi those used in the old fashioned frame, but they are not injured in strength by cutting tenons. Some builders of balloon frames notch the under side of the joists, and lock them over the strips. There is no advantage in this, as an extra spike will answer the same purpose, save the work, and preserve the full -strength of the timber—4 by 4 studs will be found best adapted to the corners. The manner of splicing studding is shown in fig. 4. A building designed for storage should be lined diagonally, to prevent a possibility of being thrown out of a perpendicular. ' Barns require no lining, except as rendering more comfortable the portiona used fur horses and cattle—a single strip 4 or 0 inches wide might be nailed to the studding diagonally. Dwelling houses do not require any such strength- ening, though diagonal strips add very much to the stifl'ness of the frame. The balloon frame is simple in its construction, and from practical experi- ence I give the preference to that form of it which is entirely free from mortices and tenons—that which costs the least labor is the strongest.
