FEKCmG. 33 



cattle of different sizes, or birds, are required to be 

 enclosed or kept out, five wires are best ; or for a 

 boundary line between two neighbours even six wires 

 may be used ; or w^here it is required to fence sheep 

 as well, seven wires are required. It is always 

 preferable to use galvanised wire, not only for its greater 

 durability, but because it shows out to the stock so 

 much better. A w^ire fence for Ostriches should never 

 be less than 4 feet 9 inches in height, as it then 

 catches above the bend of the Ostrich's neck, and stops 

 the bird trying to get over, as it otherwise will do. A 

 four- wire fence should be made of all No. 3 B.W.G. 

 wire. A five-wire fence should have the three top 

 wires No. 3, the others No. 4. In a six or seven wire 

 fence the lower wires may be No. 5. The number of 

 yards of wire to the ton, the sizes measured by Bir- 

 mingham wire-gauge, are : — 



No. 3 ... ... 4,570 yards. 



No. 4 5,455 „ 



No. 5 6,580 „ 



But it must be borne in mind that the colonial ton 

 is only 2,000 lbs. ; so that No. 3 wire runs two yards 

 to the pound ; or, in other words, a colonial ton will 

 do 800 yards of five wires of No. 3 wire. To con- 

 struct a thoroughly good fence, the farmer should 

 always purchase the best poles he can get, not Ies8
