Henny, and Bullmer, the pure chalk is loft, and a heavy, 

 cold, foil prevails upon a chalky clay. 



The valuable meadows along the river Stour, are much 

 injured by the pending up of the water by the mill dams. 



Proceeding fouthward from Middleton, the country is 

 broken into hills ; but through the parifhes of GREAT 

 HENNY, TWINSTEAD and LAMMARSH, it is en- 

 riched with fome fertile vales, and a large portion of excel- 

 lent turnip land ; the underftrata of which, are a red and 

 white fand, and gravel, interfperfcd with feveral fmall veins 

 of brown clay. CrolTing the valley, and afcending from 

 Lammarfh, to ALPHANSTONE, the land changes to a 

 heavy cold thin foil, upon a red clay, or tile earth ; a 

 brown clay, or brick earth ; a blue and white chalky clay ; 

 and in fome places, a gravel. The ftiff heavy cling foil, 

 generally prevails through this parilh, and often requires 

 feven' or eight ploughings, before it is brought into a pro- 

 per {late to receive the feed of wheat, barley, or even of 

 black oats. 



This variety of underftrata, in a great meafure forbids a 

 regular and even courfe of hollow draining, and has occa- 

 fioned the ufe of the land fail plough, which operates in 

 bringing the field to a more uniform level, by filling up the 

 fmall hollows with the earth removed from the higher 

 ground : by this means the open drains are cut upon a more 

 evenly inclined plane, and the furface water is carried away 

 with a greater, and more regular certainty : the earth 

 however, from the want of hollow drains, ftill retains 

 a confiderable quantity of water, which frequently periflies 

 the feed j and by the chill it produces (even in the moft 

 favourable feafons) greatly retards the powers of vegetation.
