At the N.E. corner of our map of 1778 will be seen a small portion of 
the Thames river-wall. This wonderful work, now generally attributed to 
the Romans, may be well studied in the marshes hereabout ; but to have an 
adequate conception of its extent and importance, a careful examination 
should be made of the Ordnance Maps from Greenwich to Thames mouth, 
including the Medway and the various creeks and streams on both banks. 
Roman temples and Roman amphitheatres sink into utter insignificance in 
comparison with this gigantic tide-barrier.
