The Expositor is a rare Chapter Operations Manual / Fraternity History for Lambda Chi Alpha. Edited by Bruce McIntosh back in the 20's. I lucked out and was able to get my hands on a copy on Ebay some time ago.
It is a pretty interesting read. My copy is currently on loan to my active chapter's High Beta for reference material. So Trey, if you are in Greensboro, you have my permission to borrow it, but I warn you that the binding is in poor shape so please be careful with it.
Here is a link to a Cross And Crescent article on the manual
