68. ESSEX CORNFIELDS. 



A rolling expanse of undulating country, mostly cornfields, extends 

 from beyond Fyfield in every direction. The section north-westward 

 between that place and Bishop's Stortford will afford opportunities of 

 observing what may be considered the characteristic flora. The subsoil is 

 a gravelly loam, more or less mixed with calcareous grit ; paths through 

 the cornfields and lanes everywhere, from hamlet to hamlet, render access 

 easy. Near the village of Hatfield Broad Oak is an extensive forest, 

 private property, and not open to the public without permission.

69. HERTFORD HEATH AND SURROUNDING WOODS. 



Hertford Heath is situated on high ground, between Hoddesdon and 

 Hertford. It is surrounded by woods, and has nothing in its aspect in 

 common with the sandy heaths south of the Thames, but, from being much 

 overgrown with bushes, has a great resemblance to Epping Forest. It is, 

 however, of a more open character to the left of the Hertford road,
