ARBORETUM AND FRUTICETUM.

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 offj these shoots have grown vigorously eversince; 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 becomeas handsome a plant as it was before the accident. — J. T. M. August, 1837.”

Geography, History, §c. P. canariensis is a native of the islands ofTeneriffe and Grand Canary; where it forms extensive forests, from thesea shore to an altitude on the mountains of 6700 ft.; though it is mostabundant between 4080 ft. and 5900 ft. above the level of the sea, which may beconsidered as the pine region of these islands. This pine has been long noticedby travellers who visited Teneriffe; but it was confounded with P. maritima,P. Tie'da, and even iarix europae'a, till the name of the species was settledby Professor Smith of Christiana. In its general appearance, Messrs. Webband Berthollet observe, P. canariensis resembles the European species; andthe first view of a pine forest in the Canaries is very similar to that of apine forest on the Alps. Under these gigantic trees, the soil is dry andpoor; and very few plants grow beneath their shade. The pines grow on themargins of the valleys, and on the steep slopes and rugged precipices whichform the sides of the mountains, but not on their summits. (Hist. Nat. de
