33. COLNEY HEATH. 



North of the ridge referred to in preceding sections as extending east- 

 wards and westwards of Stanmore Heath, there are no indications of 

 more than a very gradual inclination towards Hatfield and St. Albans. 

 About midway between these towns, and a mile or so from the Spring 

 Field station on the branch line of railway which connects them, is an 

 unenclosed patch of common, partly furze-grown, known as Colney Heath ; 

 the sluggish rivulet which drains it is a feeder of the Colne. The higher 

 furze-grown portion is on the western border ; the banks of the rivulet 

 are swampy ; subsoil, gravel. Shady lanes lead to it from different direc- 

 tions, and in the immediate neighbourhood areN. Mimms and Tittenhanger 

 Parks; adjoining the common, and opposite a windmill, is a detached 

 heathy portion, upon which are some pools.
