PZirus Linn. Pine. 



[P. SYLVESTRis Linn. Scotch Fir. 



Abundant in prehistoric times, as shown by the profusion in which it 

 is found, below the peat, in our bogs. There is, however, very little 

 evidence to prove that any trees of the Scotch fir, now growing in Ire- 

 land, have descended from the indigenous stock. As we learn from Joyce, 

 the Irish term for this tree — Giiimhas {guse) has seldom been used in 

 naming localities ; and he further points out, that, in the few cases where 

 the name does occur, the reference may have been to the abundance of 

 fir-wood in the bogs. The philological argument, which, when applied 

 to the yew, proves its former abundance, would, as respects the Scotch 

 fir, indicate its comparative rarity, during the times when this country 

 was occupied by the races who imposed our local Celtic names.]
