A NEW LONDON FLORA. 



trodden by thousands of persons, and enclosed on all sides, but the park, 

 by suburban villas of recent construction. The subsoil is gravel, and the 

 surface in many places is pitted with depressions, whence this material 

 has been dug out. These hollows may be examined, especially a large pit 

 at the north-east corner of the plain, whence the road leads down to the 

 flats by the Thames ; elevation, 140 feet. 



The marshes have Ions; since been drained, enclosed, and converted into 

 market gardens. The intersecting ditches by the roadside, and riverside, 

 however, still afford a few plants characteristic of the locality ; subsoil, 

 alluvial.
