Pen-and-ink and watercolor. Structures drawn in elevations, numbered, and identified by a legend. "The artist who drew this diagram, not being acquainted with any rules of drawing, hopes it will be sufficient apology for the imperfections which may be found." "It is not drawed from any measurement or scale, but the buildings are placed nearly in their natural situation." Available also through the Library of Congress web site as a raster image.
