Still other methods of stacking are the pole-and-boom and the poles- 

 and-cable methods. With the pole-and-boom method, a pole, held in posi- 

 tion by guy wires, ropes, braces or other supports, has a swinging boom, 

 to which are attached pulleys, cables and large horse hay forks or slings. 

 With the poles-and-cable method a cable, on which hay carriers work, is 

 stretched between two poles. With both these latter methods the hay 

 is usually taken from wagons. They are little used. (See page 314.)

From those who use the stack as a means of storage an effort was 

 made to learn the kind of stack that is preferred and the method of its 

 construction. There are two different types of stacks, the rectangular 

 and the round.
