etc., may be of any straight grain material free from loose 

 knots and knots which materially weaken the stick. Lay 

 floor joists directly upon the sills. Where two joists 

 form the span, use the lap joint. In all cases, place one 

 bow of the joist up. Place solid 2" x 6" bridging at the 

 ends of each joist, and if span exceeds 12', place 1" x 4" 

 cross bridging in the center. 



Corner studs should be 4" x 4". . The plan indicates 

 methods of placing studs. 



Headers over window openings and door openings 

 should be double. 



Girts of 2" x 4" scantling should be placed 

 horizontally in all outside walls midway between the top 

 and bottom plates. 



Place ceiling joists directly over the plate and 

 nail securely to the rafters and toe nail into plate. 



iVhere two sticks form the span of a ceiling 

 joist, lap them over the center partition or over a 

 studding. 



ROOF. 



Rafters and other members of the roof frame 

 should be of selected straight grain lumber; 1st choice 

 Douglas fir, 2nd choice Yellow pine, 3rd choice White fir, 

 free from knots and other imperfections. 



Care should be taken to cut the rafters true in 

 order that they will rest firmly on the plate, meet square- 

 ly at the apex of the roof, and that the jacks have a good 

 bearing on the hips. 



Roof projections should be sheeted solid with 

 1" x 12" rough or dressed lumber, depending upon circum- 

 stances. 



Rafter ends should be finished in the manner 

 illustrated by the diagram "Section" 



Either Star A Star .Red cedar or redwood shingles, 

 or Bugar pine or White fir shakes may be used. Shingles 

 should be laid 4-J-" to weather on sheeting 8" on center; 

 24 inch shakes 6 inches to weather; 30 inch shakes 9 inches ; 

 and 36 inch shakes 15 inch to weather. See Table No.
