LOCALITIES. 



1. HAMPSTEAD HEATH. 



A road from Hampstead to Highgate, which leads along the crest of the 

 northern heights, separates what is called East Heath from West Heath, 

 Height of the ridge, over 400 feet ; subsoil, sand. East Heath is a grassy 

 common, with a pond above, and some reservoirs at the lower part of it. 

 West Heath slopes to the north-west, and is divided by a road through 

 North End to Hendon, into two portions. The sand which caps the for- 

 mation is most apparent in the section nearest Highgate, and here the 

 ground is much broken into pits and hillocks. In the hollow of the 

 further slope is a bog, which drains into a pool below. Much Bracken 

 here, with a few white- and black-thorns.
