The title of this map of the River Thames' course runs along the top, with a scale bar at bottom centre. A note below the plan gives an account of the geographical features of the river, with a table indicating distances and fares of barges between points of navigation. A second note gives instructions on docking for goods coming from overseas with key to docking reaches at top right. Geographical features and built-up areas are indicated by symbols, with the soundings of the water expressed in feet at various points along the river.
