EXIV | GUNNAR SCHOTTE. 
If we scrutinize the figures in Table VI, we find a strikingly smaller percent- 
age of crooked trees, fewer c and (c) trees, in the Scottish woods. Thus, for 
instance, we find in the unthinned woods of undoubted Scottish origin only 
1—06' 2 of c trees. The number of trees. marked (c) mayfreachi2orsma 
the unthinned Tyrolean woods, on the other hand, we find as many as 5— 
39 & C trees, and 6—30 2 trees marked. (c). 
The present' writer also lays stres upon the fact that the Scottish race is 
somewhat more quick-growing than the Tyrolean larch. This cannot be di- 
rectly proved by figures from the experimental plots, because, as has been 
mentioned, the older areas are, as a rule, of Scots race, the younger of Ty- 
rolean. Only from Omberg Crown Park is there a comparative experiment 
which confirms the present writer's view. When the Scottish horticulturalists 
and arboriculturists (members of the Royal Scottish Arboricultural Society) were 
travelling round Sweden in 1904, and also visited the Omberg Crown Park, 
they were struck by the fine larch-wood at S. Djurledet (sample plot 280). 
With no idea that these belonged to the Scottish race, they offered to send 
genuine Scottish larch-seed for experiments in the Crown Park. In 1905 the 
seed thus obtained was sown in the nursery, and at the same time there was sown 
there larch-seed of Tyrolean origin. The plants were afterwards planted out 
in the spring of 1907 on a clearing. The development of these plants is 
shown by the figures given on pp. 613—9614 and by fig. 31. Most striking, 
however, is the greater straightness for the Scottish larch. Of Scottish larch 
only; 1.5 2 were noted as c trees and 10.3 &Z as (c) trees; while the tlbpro- 
lean larch gave 31.5 2 extremely crooked trees (c and cc trees) and 19.5 24 
lesstcrookeditrees,(c)itreesstiSee too Table 6b. 
Finally, the Scottish race seems also to be characterized by less branchy and 
less serubby crowns and by having smaller crowns than the Tyrolean larch. 
No direct comparison between old woods of the two different races can be 
made, however, because, as has already been mentioned, all older sample 
plots belong to the Scottish race, as a rule, and all younger to the Tyrolean. 
The above shows that in the Scottish larch we seem to have obtained a 
fairly uniform race, quite isolated from the race-mixture found in the Tyrolean 
larch. We may assume, of course, that none of the distinctive characteristics 
of the Scottish larch could have been formed during so short a period as 
150 years under the influence of Scottish climate or Scottish methods of treat- 
ment. Rather is the fact that the characteristics have beeen inherited from 
relatively few mother trees with hereditary good characters: what would 
seem to have taken place is not a transformation of race-characters, but 
only an isolation of races already existent. 
c. Especially erooked and spriggy trees or trees with other misgrowths (trees of a worse 
"wolf '-type or what are called "fire-wood” trees); and badly forked trees are also en- 
tered here, and when especially crooked trees are encountered they are indicated by cc; 
(c.) Trees with minor bends or inclination, which are not regarded as having a serious 
effect on the lumber value; 
d. Trees with squeezed crowns or with crowns damaged because of influence from ad- 
joining individuals; 
(d.) Trees standing somewhat close together, but whose crowns have not been directly 
deformed thereby; 
e. Diseased trees (because of attacks by fungi or insects); 
f. Desiccated trees.
