The 4£" by 3" foundation-plate is fixed to the masonry foundation 

 by £-inch bolts, in the same way as has already been described. This 

 plate is tarred. 



The posts of the framework are about 7' 6" apart. They are 

 4£" by 3" scantlings, but posts other than corner posts are usually 

 4£" by iy in cross-section. The two intermediate posts in front of 

 the shed are carried on hardwood feet consisting of 6" by 6" scantlings. 

 As shown in the drawing, each of these hard-wood feet has a cross-piece 

 (also of hardwood) attached by two |-inch bolts to its underground 

 portion. These cross-pieces serve as anchors to prevent the roof from 

 being lifted by strong winds. Both feet and cross-pieces are tarred. 



The rails or intermediate horizontals are 4£" by 1£" scantlings. 



The 4£" by 3" roof-plates are set on edge and are checked into the 

 upper ends of the posts as shown. Since the four posts along the open 

 front of the shed are spaced more than 8 feet apart, the front roof-plate 

 must have extra support. This is furnished by the diagonal struts 

 shown, which have their ends checked into posts and roof-plate 

 respectively. 



The rafters are 6" by 1£" spaced 5 feet apart. 



The purlins are 3" by 2" set on edge. 



Only the wooden framework and the foundation of the shed are 

 shown in the drawing. The back and ends are designed to be clad 

 with galvanised corrugated iron. The roof-covering, of course, is also 

 of this material. 



Lean-to Shed for Stock. — Very often, cheap shelter for live-stock 

 can be provided in the form of a shed arranged as a lean-to against 

 the wall of another building. The frame-work for such a shed is illus- 

 trated by Fig. 87. It is very similar in construction to that of the 

 implement shed which has just been described. 



The extreme width of the shed is 11' 6" from the brick wall to 

 the edge of the roofing iron at the eaves. The clear height from the 

 ground to the lower edge of the front roof-plate is 6 feet. This is too 

 low for full-grown cattle, and the shed under discussion is intended 

 for use only for young stock. If full-grown cattle are to be accommodated 

 it is desirable to have this height at least 7 feet in the clear. 



The rear 3" by 3" roof-plate (or wall-plate) is bolted to the brick 

 wall by f-inch bolts which are provided with large washers, consisting 

 of flat bars of iron about 6" by 2" by §", next their heads, i.e. on the
