ELEMENTARY AGRICULTURE 
B is placed over the ends of the rods at the back of the 
frame. By turning this board all the rods turn at the 
same time. Another board D contains three holes one 
inch in diameter, arranged in triangular manner. These 
holes are three and one-half inches apart. A piece of 
rope is fastened to each end of board D and passes 
around the person’s body that holds the twine. 
Setting Up the Machine for Use.—Set two posts 
with smooth sides into the ground so they will not give. 
Fig. 25.—Barnyards well arranged. 
These posts should be close enough together so the ends 
of the frame may be nailed to the post. The best dis¬ 
tance from the ground will be determined by the height 
of the boys or girls. Usually the frame should be about 
waist high to the workers. The cranks and the board for 
turning the cranks is next put into place. The rope, 
fastened to the board containing the three holes for hold¬ 
ing the cord, is then placed around the waist of one boy, 
and he is stationed 25 or 30 feet in front of the machine 
for turning the cords.
