EXTINCT SPECIES. 

 Pinus Picea. 



An old man told me that he found a fir tree, about six feet below 

 the surface of the ground, when digging peat at the east side of Unst. 

 It was about forty feet in length, and about six feet in circum- 

 ference. It was much decayed on the outside, but quite sound in the 

 heart. 



The cones of the Silver Fir (according to Dr. Neill) have been 

 found in the peat moors in Orkney, although I am not aware of their 

 being observed in Shetland ; and as this species seems, when planted, 

 to succeed the best of all its tribe, it may be supposed that the tree 

 in question was of this species. 



Corylus Avellana, 



The nuts and trunks of this tree have also at different times been 

 dug up in the peat moors.
