A brief description and cut of a hog house in this booklet may advance some ideas profitable to the farmer as well as the mechanic. The plan in the illustration is 24x40' and should be set east and west, The depth of stalls is 10' and the feed way 4'. (Fig. 58.) The height of outside walls is 6' to rafters. The north roof laps over the south roof far enough to admit a row of windows that will let the sunlight on the north floor. The troughs may be made of concrete. Arrange the partitions so they may be removed and hung on pins on the side. (Fig. 59.)

Excavate for the wall 18" below the surface and make the wall high enough above the surrounding grounds to keep a dry floor. Fill the walk with moist earth and tamp thoroughly. Concrete floor to be 4" thick and extend 1" over the wall. The center along feedway to be 2" higher than the outside for drain. Place bolts in concrete on both sides of all openings not more than 6' apart to bolt sills in place. The wall between the bin and stall to be 2" to 4" higher than the floor, to keep bin dry.
Place the sills and space for the studding. Cut a top plate the entire length and space the same as the sill. Cut the studs the proper lengths and nail to the plate. Raise and nail the bottoms on the sill. Set the inside posts 4"x4", every 6' on center, and 4' apart in the clear for the feed way. The plates for the 4"x4" posts to be 2"x6". One nailed on the outside of the 4x4 and the top plate to lap over the side plate. There are 9 1/2 base feet from the outside plate to the inside plate; 6" rise to one base foot would make the inside plate 4' 9" higher than the outside plate. See common rafters for length and cut, or the base 12" and rise 6"; laid 9 1/2 successive times for the length.
