above the ground line and the bottom about 12 inches below. One 
of these extra wires is placed in the face side of the post and the 
other in the back, so that they help to bear the strains on the post. 
In case of four extra wires, one is placed in each corner of the 
post with the other reinforcement wires.

Amount of Labor Required for Making Posts .—No definite 
statements can be made as to the amount of time required 
to make a cement or concrete fence post. The amount of 
time will vary with conditions, handiness of materials, methods 
of mixing, etc. According to data obtained in the experiment, two 
men mixing by hand, with everything reasonably handy, can make 
from three to five 5-inch poured line posts per hour. Figuring labor 
at $2.00 per day, ten hours for each man, the cost for making a post 
would amount to about 10 cents each. Three men with a small home 
made mixer and a two horse-power gasoline engine for driving it,
