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 
compression, it is argued that the strength of the hollow post would 
be nearly as great as that of the solid post.
