species must all be noted as introduced, not native, I did not 

 obser%-e any oaks higher up than about 700 or 800 feet. 



Through the kindness of Miss J. G. Watt, I had some observa- 

 tions made at Tomintoul (alt. 1160 feet) this summer on forest 

 trees. These, along with my Braemar notes, may be concisely 

 given in the form of a list of species observed at an altitude of 

 1100 feet and over. This limit is fixed because it covers both 

 Braemar and Tomintoul, and not because any scientific value 

 attaches to an elevation of 1100 feet. Nor can any deduction or 

 infei'ence be safely made from the list as to the limits up to which 

 the species named can grow on our mountains. It is, in short, an 

 " observational," not a theoretical list. 



Near Tomintoul, at a height of about 1200 feet, is an interest- 

 ing peat-moss. It is being cut for fuel, and shows a depth of 

 some ten feet in places. In it are found trunks of large trees : 

 the species I have not ascertained, but the probability is that it is 

 the Scots pine. The local story is that this wood was burned by 

 our "auld enemy " the English in "Queen Anne's time." It is 

 much more likely that this and the remains of other burnt woods 

 frequently found in the Highlands are evidences of the primitive 

 methods by which the eai'lier inhabitants cleared the land for 

 their own purposes.
