The flats by the Thames, which extend thus far from the eastern districts 

 of London on the Essex shore, are here broken for a short space, by the 

 intervention of a low chalk ridge, which extends for some distance beyond, 

 in the direction of Grays and Tilbury ; with flats again, however, between 

 it and the river. Here are old and extensive excavations, and a low hill 

 with overlying gravel drift, well wooded. Many plants of the chalk for-
