HOLLOW POSTS. 



It has been suggested that the cement and concrete posts should 

 be made hollow. The hollow post would require less mixture and 

 it would also be lighter. As the material in the center of the post 

 does not have a good opportunity to act to the best advantage in 

 <:t. mpression, it is argued that the strength of the hollow post would 

 be nearly as great as that of the solid post.
