The lower figure is a sort of Clay, which generally has 
more or less red or reddish brown sand im it, and is used in 
great quantities for making coarser pans, garden pots, &c. 
It is little else than a stiff loamy Earth of the farmers, 
when it is too coarsely mixed with gravel for the potters, 
which at the same time is convenient for the purpose of the 
former, and helps to separate it for the growth of plants. 
A little addition of common gravel might sometimes greatly 
help such a soil, and be a little saving as to the quantity of 
Lime. Good oak lands are nearly of this nature.
