HISTORY AND GEOGRAPHY OF TREES. PART 1 



Trevelyan, Esq., the total number of ligneous plants consists only of fifteen 

 species, which are all under the height of 3 ft. They are as follow : — 



^osdcece. JRosa. 



'Rmpetre<s. JS'mpetrum nigrum. 



'Rricdce<s. JSJrica cinerea, Calluna vulgaris, Chamseledon procumbens, 

 YacciniecB. Facclniura ritis-Idse^a, uliginosum, and Myrtillus. 

 SalidnecB. SkXh. caprea, jphylicaefolia, hastata, lanata, arctica, and herblicea. 

 ComfercB, Juniperus communis. 



The Faroe Islands, Mr. Trevelyan, who resided on them for some years, 

 informs us, are twenty-two in number, and are situated between 61° 26'' and 

 62° 23' N. lat., and 6° 17' and 7° 43' W. long. Only seventeen of them are 

 inhabited. Most of them may be compared to the summits of mountain ridges, 

 rising out of the ocean to the height of nearly 3000 ft. There is usually deep 

 water close to the land, which often rises in perpendicular cliffs to a height 

 of 1200 ft. and 1500 ft., and, in one instance, to above 2000 ft. The climate 

 is generally mild, but damp. It is not subject to extremes of temperature ; 

 the mean of mild years being 49°, and of cool years 42°. The highest tem- 

 perature during four years was 72°, and the lowest 18°. The only corn 

 cultivated is the Scotch bigg, and that does not always ripen. In the peat 

 bogs occur the remains of birch trees ; but these do not now grow in the 

 islands, having probably been extirpated by being used as fuel. 



A general view of the arboricultural flora of Sweden, considered geogra- 

 phically and geologically, has been prepared for us by the celebrated botanist 

 Br. Agardh, formerly professor of botany at Lund ; and we have received 

 another for the whole Scandinavian peninsula, by Professor Schouw of 

 Copenhagen ; but, as these communications, though excellent in themselves, 

 are somewhat too long for insertion in this work, we have transferred them 

 to the pages of the twelfth volume of the Gardener's Magazine ; contenting 

 ourselves here with some abridged extracts from them, relative to the intro- 

 duction of foreign trees into the Scandinavian peninsula. 



Foreign trees and shrubs have been introduced into Denmark and Sweden, 

 chiefly in the different botanic gardens, and in the grounds of the royal resi- 

 dences at Copenhagen and Stockholm, and of the wealthy proprietors in the 

 neighbourhood of these capitals, and of the other large towns. There are, 

 however, but few American trees or shrubs to be found as standards in the 

 neighbourhood of either capital. The largest indigenous trees in Denmark 

 are beeches, of which one, in the park of Jagersborg, exceeds 100 ft. in 

 height. The white poplar also grows to the height of 100 ft., and the oak and 

 Scotch pine attain a great size. At Dronninggaard, near Copenhagen, the 

 tuhp tree, in 40 years, has attained the height of 80ft., and also the horse- 

 chestnut. The Ilob)n2« Psei'id-^cacia, at the same place, has, in 40 years, 

 attained the height of 60 ft. ; but the Gledltschk triacanthos, in the same 

 period, only 16ft. O'rnus europae'a is 30ft. high; J'bies Picea, the silver 

 fir, 100 ft.; and A'hies canadensis, only 6 ft.; while Pinus iStrobus becomes a 

 considerable tree. At the royal gardens of Rosenberg, near Copenhagen, 

 there is an excellent collection, planted for the most part in 1831, 1832, and 

 1833, a list of which, with their dimensions, has been kindly sent us by the royal 

 gardener there, M.Jens P. Petersen, On looking it over we find that it contains 

 nearly all the species procurable in the London nurseries. Among the hardy 

 trees, however, the cedar of Lebanon is not included, nor the common 

 laurel. In the garden of Christianholme, near Lolland, there are some good 

 trees, the dimensions of which have been sent us by the curator, M. Gentz. 

 Here the tulip tree and the J^cer dasycarpum are 40 ft. high ; the robinia, 

 36 ft.; the gleditschia, 24 ft,; the O'rnus europae^a, 24 ft.; the walnut, 30ft.; 

 the Lombardy poplar, 80 ft, ; the purple beech, 30 ft. ; the platanus, 80 ft. j 

 and the larch, 75 ft. 



In Sweden, according to Dr. Agardh, " the central points from which foreign 

 trees' and shrubs have spread over the whole country are, Lund, Upsal, 

 Stockholm, and Gottenburg. Some of these introduced trees, such as L^rix
