Wall girts of E" 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 5 - EOd. wire nails for nailing the ceiling joist to the 

 rafters and 2 - 20d. wire nails to toe nail them to the plate. 



ROOF. 



Materials for roofs of different pitches are pro-r 

 vided. At elevations within the respectiye ranges use the 

 roofs of stated pitches. Exception to the above should 

 occur only where snowfall is not a sourpe of hazard as pn 

 some of the southern Forests and orj the J\Jodo,Cj 



Where roof trusses are need fasten the members 

 securely with 10d. nails in members 1 inch thj.ck and with 

 20d. nails in members 2 inches thick. 



Rafters and other members of the roof frams 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 

 cannot be given to the selection of the best sticks of the 

 lumber order for rafters. 



Care should be taken to cut the rafters true in 

 order that they rest firmly on the plate, meet squarely at 

 the apex of the roof. 



Eave projections should be sheeted solid with 

 1" x 12"" rough lumber. 



Rafter ends should be finished in the manner illus- 

 trated by the diagram "Section".
