School Assembled [version 2], c.1900

View looking north of what is presumably the entire student body assembled in neat rows on the central campus. Groups of spectators, probably teachers and staff, are standing or sitting around the nearby buildings. 

This glass negative appears with a collection of other negatives attributed to photographer M. J. Hoover, but he most likely either made a fresh copy from the original negative, or else he simply acquired the original negative and incorporated into his own collection since the image definitely dates from a time before he was operating as a photographer in the town of Carlisle.
