Political cartoon depicting Brother Jonathan (the national personification of New England during the Civil War) perched atop a "stone fleet". He prepares to plug in rat-holes labeled as "Southern Coast", "Ocaraco Rat-Hole", and "Charleston Rat-Hole". The cartoon refers to scores of old ships deliberately sunk with cargoes of stone by the Union Navy at the entrance of Charleston Harbor in an attempt to obstruct blockade runners.
