154 HISTORY AND GEOGRAPHY OF TREES. PART I 
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: — 
Rosdcee. Rosa. 
Empétree. E’mpetrum nigrum. 
Ericdcee. Erica cinérea, Callima vulgaris, Chamzelédon procimbens. 
Vacciniée. Vaccinium Vitis-Idz‘a, uligindsum, and Myrtillus. 
Salicinee, Salix caprea, phylicefolia, hastata, lanata, arctica, and herbacea. 
Conifere, 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° 25’ 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- 
seo) and geologically, has been prepared for us by the celebrated botanist 
r. 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 
tulip tree, in 40 years, has attained the height of 80ft., and also the horse- 
chestnut. The Robinia Psetid-Acacia, at the same place, has, in 40 years, 
attained the height of 60 ft.; but the Gleditschia triacanthos, in the same 
period, only 16 ft. O’rnus europe‘a is 30 ft. high; Abies Picea, the silver 
fir, 100 ft.; and A’bies canadénsis, only 6 ft.; while Pinus Strobus 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 A‘cer dasyc4rpum are 40 ft. high; the robinia, 
36 ft.; the gleditschia, 24 ft.; the O’rnus europz‘a, 24 ft.; the walnut, 30 ft. ; 
the Lombardy poplar, 80ft.; the purple beech, 30 ft.; the platanus, 80 ft. ; 
and the larch, 75 ft. of 
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 Larix
