Lap top plates at corners and in splicing top 

 plates lap them 4 feet and arrange to have the end of the 

 lap rest upon the studding. Hail plate to studs with 20d. 

 nails. 



Headers over window openings and door openings 

 should be double 



\Vall girts of 2" x 4" scantling should be placed 

 horizontally in all outside walls midway between the top and 

 bottom plates. If water table is used a girt should be 

 placed just below table to give nailing foundation for siding 

 under water table. In such cases the wall girt should be 

 placed midway between the water table and top plate. 



Place ceiling joists directly over plates. Nail 

 them securely to the rafters and toe nail them to the plate. 

 If the building will be subject to snow load for ceiling 

 joists, give particular care to the selection of good 

 straight grain sticks free from knots larger than 1 inch in 

 diameter and other imperfections that would weaken the stick. 

 Use five 20d. wire nails for nailing the ceiling joist to 

 the rafters and two 20d. wire nails to toe nail them to the 

 plate. 



ROOF. 



Materials for roofs of different pitches are pro- 

 vided. At elevations within the respactive ranges use the 

 roofs of stated pitches. Exception to the above should oc- 

 cur only where snowfall is not e source of hazard as on some 

 of the southern Forests and on the Modoc. 



Where roof trusses are used fasten the members 

 securely with lOd. nails in members 1 inch thick and with 

 20d. nails in members 2 inches thick. 



Raftfcrs and other members of the roof frame should 

 be of selected straight grain lumber; first choice Douglas 

 fir, second choice white fir, third choice yellow pine, free 

 from knots and other imperfections. Too much attention can 

 not be given to the selection of the best sticks of the lumber 

 order for rafters.
