FORESTS AND FOREST TREES. 179 



should be considered rather as a variety forming a transi- 

 tion to the Picket 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 in a 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 

 (58 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 tivanevigen (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,
