Conductors are made plain round or square, and corrugated round 

 or square. Corrugated conductors are to be preferred to plain conduc- 

 tors for the reason that they will give when the ice freezes inside of 

 them, and will not burst as the others often do. Common sizes of round 

 pipe are 2", 3", 4", 5", and 6" diameter. Common sizes of square 

 pipe are i%" x 2%", 2^" x 3 M", *A" x 4 M" and 3^" x 5", 

 equal to 2", 3" and 4" round pipe, respectively. Conductor pipes are 

 fastened with hooks or by means of wire.
