5 14 Improved Grain-Drying Sheds. [dec, 



each, about 12 in. from the foot, and an iron rod 1 ft. 9 in. by 

 i\ in. is put through the hole (Fig. 5, BB). 



The four stays or ranees are " H " joists, 6 in. by 3 in., and 

 are bolted to the strainers and to the first intermediate post 

 (Fig. 5, CC). It is absolutely necessary that the foundations 

 of the four strainers should be thoroughly secure, as the whole 

 structure when filled with grain presents so great a surface 

 to the wind. Intermediate standards of " H " iron, 6 in. by 

 3 in., with wood 3 in. by 3 in. bolted on each side (Fig. 4, DD 

 and Fig. 7) are erected 4 yards apart from end to end. These 

 are 20 ft. long, and 4 ft. of each is embedded in concrete, in the' 

 same way as the strainers but without the through iron rod. 



fig. I. — North Side of Shed. 



On these intermediate standards solid galvanised wires (No. 6) 

 are supported, after being attached to the strainers by the 

 eye-bolts. 



Staples are used to support the wires, and should be driven 

 in the wood bolted to the intermediates, at an acute angle and 

 so driven that the wire will rest on both legs of the staple and 

 only sufficient left undriven as will support the wires, besides 

 leaving room for a wire to pass down perpendicularly through 

 the staples to keep the horizontal wires which rest on the 

 staples confined between the wood of the intermediate standards 

 and the perpendicular wire. Staples 2 \ in. long, made of 

 No. 4 wire (galvanised) will suit and they should be driven in 

 about 1\ in.
