Soil, 



Note. — The soil was powdered by mistake, therefore gravel could not be 

 determined. 



SOIL FROM MR SWANWICK, WILTSHIRE. 



This soil differs remarkably from all the others. It dries up 

 into clods as hard as bricks, having an exceedingly pale colour. 

 Moistened with water, it becomes extremely plastic, and might 

 almost be used for making bricks. Notwithstanding its pale 

 colour, it contains much organic matter, and when heated, 

 exhales the smell of burning peaty matter. It is very free 

 from stones. The subsoil is similar in all respects, and still 

 lighter in colour.
