In the “Chemistry Dept. 1832-1968″ vertical file, you’ll find this document. The caption reads:
The chemistry lecture room in old Judd Hall.
Prof. M.L. “Mose” Crosley was lecturing on the
last day of classes prior to the final exam.
The device at the right moved a huge roll of
wrapping paper by means of the chain. A wax
crayon could be used. Lots less work than the sliding
dusty blackboards up front! (Last page in my note book)
