The Old Mill No.4: Office of the Chief Engineer

PHOTOGRAPHER'S JOURNAL:  "A Day at the Mill, Pt.4":  As it turns out, the passage was a storage closet lined with shelves of  gears, wheels, cams; parts to a puzzle that no longer needed solving.  

I never reached the end of the passage. I turned back and followed other tracks, but later, having passed through a devious set of stairs and hallways, I entered a room that looked as if it had been the site of a brawl. It was clearly the engineers' office.  A large table on the back wall was laden with faded engineering plans and diagrams. A window by a desk was open and overlooked the arena, a place to watch the millworks working.
