A NEW LONDON FLOEA. 



34. BROXBOURNE AND WORMLEY WOODS. 



Northaw Common, near the Potter's Bar station on the Great Northern 

 line, is now enclosed ; these woods are therefore better and more directly 

 approached from Broxbourne, on the Great Eastern Railway. They cover 

 the low hills which border the Lea Valley on the west, and are only par- 

 tially enclosed. They are of a cold damp character, with a gravelly 

 subsoil, but with much alluvial deposit in the hollows, and along the lines 

 of drainage to the river Lea. Roads, leading from Broxbourne to Bayford 

 and Brickendon Green, intersect them from east to west ; the more direct 

 approach is through the grounds of Broxbourne Park ; the longer route 

 is via Wormley, west end. Or that from Cheshunt, via Applebury and 

 Beaumont Green, may be selected. Oak is the prevailing timber, but there 

 is no lack of scrub and of other kinds of trees, Hornbeam, Beech, Ash, &c. 

 There are indications of underlying chalk.
