THE PINE.

the seed of the best variety of the Pine, the example 

 having first been set by the Messrs. Grigor, nurserymen 

 at Elgin, and the good effect, we may remark, is already 

 visible in the appearance of the Scotch Pine plants, in 

 plantations made within the last fifteen years. Mr. Don's 

 third variety is easily distinguished from the other two, 

 for although it has the pyramidal growth of the first, 

 its leaves are still more glaucous, or of a more silvery 

 green than those of the second ; its cones also are remark- 

 able, in having the bosses of the scales elongated and bent 

 backwards, in the form of blunt prickles, from which cir- 

 cumstance it received the name of Pinus sylvestris uncinata. 

 It is not, however, to be confounded with the Pinus un- 

 cinata of Captain Widdrington, a species certainly nearly 

 allied to Pinus sglvestris, but which inhabits a still higher 

 zone, and whose distribution seems confined to the moun- 

 tain ranges of the peninsula. This variety in the Scottish 

 forests is of more frequent occurrence than the Pinus sylves- 

 tris horizontalis, and produces an excellent timber. Amongst 

 the continental varieties the Pinus sylvestris Hac/umensis, 

 (Pin. de ffaguenen,) seems one of the most valuable, pro- 

 ducing tall, straight, clean timber. The bark is of a reddish 

 colour and remarkable for its smoothness, and its leaves, 

 which are of a light and slightly glaucous green, are serru- 

 lated and much waved or twisted. Seeds of this kind 

 were brought over by Mr. Loudon, and young trees reared 

 from them are now growing and thriving in Perthshire. 

 Young plants are also to be obtained of Mr. Lawson, 

 nurseryman at Edinburgh. 



We shall now proceed to make a few observations upon 

 certain species of the genus Pinus, which, from their habit 

 and hardy constitution, promise to thrive and attain their
