In the section by Cleave Burn there is no sign of birch at the base of the peat, and 
the peat dominated by Eriophorum rests directly upon the clay. There is a sharp 
division between the two, the upper surface being smooth and indented by the weight 
of the overlying peat, and the dry compressed remains of Eriophorum and Molinia peel 
away from this surface, leaving it quite clean. The appearance suggests that some 
considerable time elapsed between the deposition of the clay and the growth of the 
vegetation which now rests upon it, during which time the clay was consolidated and 
denuded to some extent by water, after which it became covered with a growth of 
Molinia cxrulea, Moench., Polytrichum, and Eriophorum. At the same time, or possibly 
sooner, the lower slopes of these hills became covered with a shrubby growth of birch
