FENCING 237 



pushing against the fence. In woven wire the spacing 

 varies slightly with the different manufacturing firms. A 

 fence in which the spacing is considered approximately 

 correct is as follows : woven wire beginning with the ground, 

 3 inches, 3^ inches, 4 inches, 4^ inches, 5 inches, 6 inches, 

 7 inches, and then 7 inches to a barbed wire and 8 inches to 

 another barbed wire. 



Commercial lengths and weights. The wire used should 

 be thoroughly galvanized, resilient, and of a sufficient 

 degree of toughness to splice without breaking. A hard- 

 drawn Bessemer steel wire is the quality ordinarily used. 

 Galvanized wire should 

 be clean and bright when 

 purchased and should be 

 stored in a dry clean place 

 until used. Barbed wire 

 is purchased in rolls or 

 spools of from 80 to 90 FlG ' 200 ' Tw °-P° int barbed «** 



rods per roll. The weight is approximately a pound per rod. 

 Since the same diameter of wire is not always used, the 

 weight may be as much as iX pounds per rod. Woven 

 wire comes in rolls of 20 rods each. The weight will vary 

 somewhat with the gauge, but the following is the approxi- 

 mate weight for the various widths of wire: 



55-inch icyo" pounds 



47-inch 9X0" pounds 



39-inch 8yV pounds 



32-inch jyo pounds 



26-inch 6y% pounds 



20-inch 5x% pounds 



It has been learned by experience that the durability of 

 a fence depends upon the size of the wire used, the use of 

 a heavy wire being the more economical. No. 9 is con- 

 sidered the most satisfactory from the point of service and 

 of economy in durability. Data collected and published
