r mud sills for underpinning should 

 never be placed directly on the earth. Place them on foot- 

 ings of either - 



(a) Substantial flat stone, maximum dimensions ap- 

 proximately as follows: 



8 M thick, 10" wide, 10" long 



(b) Hasonry footing 



12" high, 14" square at base and 8" square et top 



If high underpinning is used it should be braced 

 as shown on Sheet 6. 



MATERIALS. 



All structural material should conform as closely 

 as possible to the specifications given in the builder's 

 list. 



SILLS. 



Sills should preferably be of ceder or redwood. 

 Douglas fir may be used as a second choice. Pine should 

 never be used unless the sill is to be 2 feet or more above 

 the ground. 



Sills p.t corners should be halved together. The 

 plan calls for one sill in the center of the building. 

 Angle braces on 45 angles should extend from each founda- 

 tion post to the floor joist just above and from each corner 

 to the sills. (See flan of foundations). 



FLOOR JOISTS. STUDDING. BRIDGING. STC. 



All joists, girts and studs should be sized, 

 IThat is, dressed down so that all sticks of respective 

 dimensions are made of uniform size.
