larch has not been tested by culture for sylvicultural purposes. As itis able 
to grow in damp ground, however, it ought to be worth while to try it on 
imperfectly drained mosses in upper Norrland. 
Chap. X. Other Species of Larch. 
Besides the species of larch treated in separate chapters — europaea, sibirica, 
leptolepis, occidentalis, americana, Lyalläi, and dahurica there are, as has been 
mentioned in Chap. II, several other species of larch. As these have little 
sylvicultural value, and are at the present time of purely dendrological interest, 
they are treated quite briefly in this chapter. Moreover they have as yet 
scarcely been tried in Sweden. These species are Larix Kurilensis, Griffith, 
Potanim, chinensis, Principis Rupprechtia, Cajanderi, Olgensis. 
Chap. XI. Summary. 
In Sweden Larix europaea, sibirica and leptolepis have been successfully culti- 
vated as forest trees. During the last few years experiments have also been 
made with Larix occidentalis. Tsolated specimens of Larix americana and da- 
hurica have been cultivated in parks. It is further considered that experi- 
ments ought to be made with Larix Kurilensis, and in the fell districts with 
Larix Lyallä. As regards the more important species of larch, this enquiry 
has brought out the following points: 
Larix europaea is cultivated over almost the whole of Sweden: in 
Norrland in somewhat isolated specimens sas far as Pitea fond 
probably also in Haparanda. It is scarcely to be födnd matbe 
inner parts of Upper Norrland. It began to be planted about 1750, 
but as a forest tree not until 1780—90. 
AS a rule, lärch plants were obtained from Great Britain, espe- 
cially from Scotland. The older larch woods obtained from there 
are distinguished by a strikingly straight stem, strong growth in 
height, relatively thin bark, and a not very bushy crown. Lhese 
characteristics are so very marked that we must distinguish a spe- 
c1lal Scottish race... Etom the middle of tNe nineteenth cc nit») 
when forest culture in Sweden had spread greatly owing to in- 
fluence from German forest literature — on the estaes of private 
persons especially through foresters who had immigrated from Ger- 
many, — larch seed came to be sent from the mountain districts 
of Central Europe, probably more and more from the Tyrol. 
The larch woods that have thus come into existence are charac- 
terized by a very high percentage of crooked stems, a somewhat 
weaker height growth, great thickness of bark, and often a rather 
bushy crown. These characters make the Tyrolean larch unsuit- 
able for mixed: forests. 'Fhus the crooked stems of certarmlareb 
woods or certain individual larches are due to inherent race pro- 
perties, and not, as was formerly assumed, to its rapidity of growth 
astcompared with other trees in the stand: 
The larch can with advantage be cultivated in pure woods on 
the best forest grounds in Sweden. On grounds of the Quality-
