nurseries in Halstenbek are under the control of the German 

 Forestry Council (Deutscher Forstwirtschaftsrat), and foreign cones 

 and seeds dare not be used. To close every door, the importation 

 of the cones of the fine strong and hardy Belgian Campiegne Pine 

 has also been regretfully prohibited. 



The seed weight results of 1888 89 have been shown to be 

 quite correct, as, to-day after twenty-five years, Table No. I shows 

 the following figures for the seed weight: 



Lowest Highest Mean 



37 Finland samples 3.79 5.82 4.54 



13 Scandinavian (mostly Swedish) 4.75 5.41 5.15 



10 West Norwegian (Nordfjord) 4.53 6.23 5.22 



33 Scottish 5.0 7.4 6.41 



4 Mid-European (Hartz and Belgium) 6.0 7.5 6.65 



1 Baltic (Livland) 5.8 



1 From the Ural 7.1 



The high weight of the last sample is striking. 



As mentioned above in discussing the spruce, I have tried if it 

 is possible by means of the -weight of the seed, to determine the 

 origin of our old Danish pine woods, and I found that the results 

 were very similar to those obtained in the case of the spruce. In 

 1911 12 cones were sent to me from old pines in the heath of Hald 

 Skramso in Jutland, and the weight of the seed was as follows: 



Weight of 1000 seeds 



Seed from the heath of Hald (5x 100 seeds weighed) 4.27 grams 



Skramso, old trees 6.48 



young trees 6.53 



The germinating capacity is good, 16 / , 48 / and 32 % respec- 

 tively, in 5 days. 



The pines in Hald are presumably of Northern, those on Skramso 

 of Mid-European, strains.
