FORESTS AND FOREST TREES. 179 
should be considered rather as a variety forming a transi- 
tion to the Picea obovata Ledebour, of Russia. Moreover; 
we meet in Finland with a whole series of transitional 
forms between the two forms named. If these two forms 
do present some differences of growth, of wood, of habitat, 
or other qualities of importance ina forestal point of view, 
it is not yet known to be the case; and the area of their 
respective homes has not yet been sufficiently observed. 
The principal form prevails almost everywhere throughout 
the country ; in the south the variety with obovate scales 
is only met with here and there; towards the north it 
becomes less rare, and on the north-east frontier it is even 
dominating. The northern limits of forests of Norfolk 
pine occurs at 68° 15’ on the western frontier, and at 
68° 45’ on the eastern. Further to the north, it no more 
forms forests, but we meet with solitary and stunted 
specimens up to 69° in the Lapland territory of Enari. It 
must also be stated that in Norway, at Svanevigen (69° 30’) 
on the frontiers of Russia, Forest-Master J. C. Barth found 
a clump of Norway pine, ascertained to be of obovate 
variety. 
‘Amongst the different kinds of trees indigenous to 
Finland the Norway pine holds the second rank, both as 
to extent of growth and in economic importance,’ 
In 1788 a Kron-park in the parish of Ny Kyrka (Newkirk) 
60° 20’, in the Government of Wyborg, situated about five 
versts from the railway station at Raivola, between Wyborg 
and St. Petersburg, was, at the instance of the Admiralty, 
planted with Siberian larch (Larix sibirica Led.) This 
tree is not indigenous in Finland, but the trees planted 
there have’ maintained their footing. At Moscow there 
were exhibited two sections of trees grown there, one of a 
height of 110 feet, and a diameter of 10 inches; the other 
of a height of 112 feet, and a diameter of 11'5 inches. 
Dr Blomqvist reports of the Siberian larch that, though 
not indigenous in the country, it has there attained great 
dimensions. Specimens are to be seen 135 feet in height,
