Figure 192. ,(1) Plumb-Bob and Plumb-Line. The line is paid 

 out about 6 feet from the spool and given a half hitch. It may then 

 be hung over the wire and the spool will balance the bob. (2) Bipod. 

 The legs of a fence bipod are cut 6 feet long. The bolt is put 

 through 6 inches from the top ends. By the aid of the plummet the 

 upper wire is strung plumb over the barb-wire in the furrow and 

 4' 6" above grade. The lower parts of the posts are set against the ' 

 barb-wire and the upper faces of the posts at the top are set even 

 with the upper wire. This plan not only places the posts in line, 

 both at the top and bottom, but it regulates the height.
