SOIL FROM MR MUNRO, FAIRNINGTON. 



The soil and subsoil in this case had a somewhat greyish tint, 

 the latter rather lighter in tint, but so similar that they could 

 be distinguished only with some difficulty. Both soil and subsoil 

 contained an unusually small proportion of iron. The gravel 

 was large in the subsoil, and consisted chiefly of fragments of 

 sandstone, with a few pieces of a felspathic mineral.
