Why the fort would need to have so many at any given time remains a mystery.
The building now called the Post Playhouse at Fort Robinson was for many years the quartermaster’s warehouse. In 1991 the building underwent renovations. When the floor was removed, thousands of items from a long span of time that had been discarded in the 1920s were found in the crawl space underneath the floor. A trap door had once allowed access to the crawl space and for some reason the quartermaster employees disposed of things beneath the floor rather than discard them in a more regular fashion. This picture is just a fraction of the number of bugle mouth pieces that were found.
