Uncle Sam protecting his property against the encroachments of his cousin John

Northern fears of European intervention in the Civil War on behalf of the South are manifest here.Uncle Sam, in the form of a bearded Union soldier (closely resembling Abraham Lincoln), unceremoniously routs John Bull from a fenced garden where the latter has been poaching. Grabbing him by the scruff of the neck, Sam warns, "John, You lost your Non-interfering Principle. I'll lay it on your back again." The American wields a large stick "Principle of Non Enterference." John Bull has a handful of cotton plants, more of which appear at right, and wears "Armstrong's Patent" cannon on his legs. (The term refers to a type of English-made gun used by the Confederates.) The artist has hidden several Negro faces in his drawings of cotton plants here. A cock with the head of French leader Napoleon III watches from his perch on the fence at left. At right stands a large scarecrow from whose arms hang the lifeless bodies of Confederate general P. G. T. Beauregard and Confederate president Jefferson Davis. A plaque on the scarecrow reads, "All Persons Tresspassing These Premisses, will be punished according to Law."
