loss of stock by lightning. The system is called the “Double Sta- 
pie.” (See Fig. 5.) 
A “single staple” may also be used, but the wire is fastened to 
the staple by a small “cold shut link,” or wire ring. The latter sys¬ 
tem is not a very strong method of fastening, owing to the ease with 
which the cold shut links open. (See Fig. 5.) 
Perhaps the most common method of fastening wires to cement 
or concrete posts consists of tieing in the line wire to the post by 
means of a piece of smaller wire called a “tie wire” (usually No. 14 
or No. 15 wire). The single tie consists of wrapping one end of

the long end through a hole in the post and bringing it around to 
the face of the post where it is also wrapped around the line wire.
