SOIL FROM MR MUSTARD, LEUCHLAND, BRECHIN. 



Both soil and subsoil in this case are dark coloured, even 

 when dry, and are so similar that it is difficult to distinguish 

 them from one another. The subsoil, however, is redder in tint. 

 There is a close resemblance also in the gravel, which consists 

 chiefly of much decomposed matter, which looks like altered 

 greenstone, and there are a few fragments of mica slate.
