810 T. M. READE ON A SECTION THROUGH GLAZEBROOK MOSS. 



A comparison of this inland moss with the peat- and forest-bed at 

 the Alt mouth is very instructive*. In the latter there is a much 

 greater variety and profusion of trees, though none so large as the 

 oak I have just described. The peat is also much harder and more 

 compressed, and the bottom contains more bark and branches. 



It is not improbable that the sandhills, which must have been 

 formerly at the top of the Alt-mouth peat, but are now washed away, 

 have assisted to compress it, the sound branches even being com- 

 pressed into an oval section. It is much older and of longer growth 

 than the inland moss just described. There has been a succession of 

 trees, and the timber itself bears marks of greater antiquity.
