September, is W. to S.W., less often S. or N.W. Easterly winds are

SOIL. 
As mentioned previously, the soil consists of Boulder Clay, which in this 
wood ean be divided into two sharply marked areas. The first, which is 
much the larger of the two, consists of a heavy stiff calcareous clay or marl, 
which is bluish or grey in colour. This soil is very fine-grained, with few 
stones at the surface but irregular bands of flints below. The surface 
soil here extending to about 1 inch in depth is dark-coloured owing to the 
presence of humus ; below this for a depth of 18-20 ins. the soil is а very 
homogeneous clay, brown to yellowish in colour, with occasional flints. 
From about 22 inches onwards chalk becomes freely mixed with the clay in 
small or larger nodules. The whole soil here іх of a much lighter grey 
colour. Even at depths of about 4 ft. the soil remains similar in character ; 
bevond this depth * probably no roots even of trees would extend in a soil 
so well supplied with water, and, indeed, in this soil, except for the trees, few 
if any roots penetrate more than about 7 inches. 
The other tvpe of soil oceupies a smaller area in the wood mainly on its 
western side. The soil here is a loam, much lighter:and more friable than 
the former type. It consists of a mixture of coarse sand and clay. There 
is an inch on е surface with a large amount of humus; below this the 
soil is darkish in colour to a depth of about 6 inches. Beyond this depth the
