PART III. 



Christiana, at Teneriffe, attained the height of 15 ft. without any protection, 

 and remained uninjured till the severe spring of 1830, when the top was com- 

 pletely destroyed. In the early part of the summer of that year, however, 

 the trunk threw out two or three shoots, a few inches above the collar, and, 

 the dead part above it being cut oft\ these shoots have grown vigorously ever 

 since ; and one of them, having taken the lead, promises to make a hand- 

 some plant. A tree of the same age in Dr. Percival's garden at Annfield, 

 near Dublin, met with a similar fate at the same time; but has now become 

 as handsome a plant as it was before the accident. — J. T. M. August, 1837." 

 Geography, History, fyc. P. canadensis is a native of the islands of 

 Teneriffe and Grand Canary; where it forms extensive forests, from the 

 Bea shore to an altitude on the mountains of 6700 ft.; though it is most 

 abundant between 4080 ft. and 5900 ft. above the level of the sea, which may be 

 I onsidered as the pine region of these islands. This pine has been long noticed 

 by travellers who visited Teneriffe; but it was confounded with P. maritima, 

 I'. Va: da, and even />arix europ;e\, till the name of the species was settled 

 bj Professor Smith of Christiana. In its general appearance, Messrs. Webb 

 and Berthollet observe, P. canadensis resembles the European species; and 

 tin; first view of a pine forest in the Canaries is very similar to that of a 

 pine forest on the Alps. Under these gigantic trees, the soil is dry and 

 poor ; Bod very few plants grow beneath their shade. The pines grow on the 

 margin-, of the valleys, and on the trip slopes and ruined precipices which 

 form the ides of the mountains, but not on their summits. (Hut. Nat. <lc
