LOCALITIES. 



169 



flats about Grays are cornfields ; about Tilbury Fort these flats have 

 somewhat of a fenny character, but less marshy now perhaps than was 

 formerly the case, owing to drainage and the embankment here as else- 

 where by the Thames.

66. SOUTHEND AND CANVEY ISLAND. 



Southend is beyond the limits of a thirty or thirty-five miles radius from 

 the metropolis, but the facility of access to the place is so great, and 

 the opportunity of obtaining many plants found only on the sea-shore 

 so favourable, that the intrusion of the locality may be freely excused. 

 High clay banks between Leigh and Southend, with muddy shore and a 

 stone embankment by the railway ; near Leigh a miniature sandy bay. 

 At Canvey Island an alluvial flat, with muddy shores and for the most 

 part cultivated ; beyond Southend, towards Shoeburyness sandbanks, a 

 muddy shore on one side and an alluvial flat on the other : such are the 

 topographical characters of the localities. The flora is varied ; and the 

 occurrence of chalk plants indicates the presence of that substance in the 

 subsoil.
