Glen's Falls (from Sketchbook)

Black and white sketch of a building and bridge. The building is in the center, made of stone or brick, with a flat roof and several levels. A bridge spans the top of the image, behind the building. The bridge has a railing and appears to be made of stone or brick, matching the building. Trees are on the right side and in the background. The foreground has grass and possibly a body of water. The image is drawn in a simple, sketchy style with minimal details. The title of the image is "Glen's Falls" and the artist is John William Casilear.
