Cement and Concrete Fence Posts. 25 
In making the posts, enough of the mixture was provided for 
the construction of three posts at once. The three were cured 
alike, for 60 days and were tested at the same time. The tables 
show the average results of the test on the three posts as one. 
In the reinforcement the short wires mentioned are two feet 
long and are placed in the post so the top extends about 12 inches 
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.
