becomes strained. The wires are fastened to the intermediate 

 posts by staples (Fig. 12). These are driven half-way into 

 the posts and the wires passed through, before the straining 

 commences. They are driven home when the straining has 

 been completed. 



Fig. 13 shows a cast-iron straining bracket fastened to a 

 wooden pillar ; this is worked with a key. It is used instead 

 of the eye-bolt. 



Where rabbits or hares are to be kept out, wire netting may 

 be added to the lower part of the fence.

The cost of the materials in England may be estimated as 

 follows : — 



Wire, imperial standard wire gauge, No. 8, about one 

 shilling per 100 feet ; galvanised, ^ more. Straining bolts, 

 12 inches long, |- inch diameter, with nut and washer, 

 tenpence each. Straining brackets (Fig. 13), tenpence each. 

 Steel staples, per 1,000, 9s. ; galvanised, ^ more. Thus the 

 iron materials come to about Sd. a yard, or 4d. if galvanised 

 wire and staples are used. The cost of the posts and of 

 labour depends on local circumstances. 



For nurseries iron fences may be used, to which wire 

 netting may be added, if necessary. Fig. 14 represents such 

 a fence. It is 4 feet high, the pillars are 2^ feet in the 

 ground, and the fence is strong enough to keep out horned 

 cattle, sheep, goats, hares and rabbits. The straining pillars.
