Summary
| Description |
English: A section of the River Thames, Richmond to Gravesend (vertical scale exaggerated), showing successive layers of clay deposition and peat growth. One layer was datable by Roman pottery. From these observations Spurrell inferred that the land has been sinking relative to the sea, with occasional remissions. The tops of the river walls, by being topped up to prevent tidal overflow, have been keeping pace.
