Joseph Pennell's pictures of the Panama Canal / Reproductions of a series of lithographs made by him on the Isthmus of Panama, January—March 1912, together with impressions and notes by the artist

An artist recounts travels on the Isthmus of Panama while producing lithographs of the canal, pairing detailed visual descriptions of locks, dams, machinery, and landscapes with personal impressions of workers, towns, and the engineering process. The narrative alternates observational sketches of dramatic construction scenes, swamp and harbor environs, and the interplay of French remnants with American works, with reflections on sanitary measures, labor conditions, and technological achievement. Notes describe everyday life in canal towns, the scale and mechanics of excavation and lock operation, and the aesthetic contrasts between industrial structures and tropical scenery, accompanied by reproductions of original lithographic images.
