The Loud Speaker &
Intercom System
 
This was the American Flag for the academy students.
This was the Booth in the middle of the camp. It was used to communicate with the office at B-8 or admin. building a fourth of a mile away.  A loud speaker was used to call the person to the booth where he then spoke by phone to the person needing him.
 
Notice the beautiful masonry done around the Booth.  There was a tough here where gold fish were kept. It was formed like a scroll up to the front of the booth.
