The cultivation at Chorin, forming part of these experiments, 

 has yielded results which may prove interesting, though the 

 experiences in Wales in this respect have already been reported 

 by Professor Fraser Story. 



Pine seed from eight different localities, obtained in the cone, 

 and abstracted under official supervision in Eberswalde, so that 

 there might be no question as to its origin, was sown on the 

 25th April before 8.15 a.m., in cool, moist weather, which 

 continued until loth May. 



The sources of origin are tabulated as follows : — 



The seeds germinated almost simultaneously. In the course of 

 the summer, however, the type differences appeared in the height 

 of the plants, the length of leaves and summer colouring, and in 

 the auttimn, in the cessation of growth. 



The seedlings from the Ural ceased to grow on the 23rd August. 

 The first frost took place on the 23rd September. Only the Ural 

 pines and the majority of those from the Kurland had closed 

 buds. The frosty nights in the beginning of November found all 

 plants prepared for the winter, with the exception of individual 

 specimens from the south of France, Scotland, Rhine, Hesse and 

 Belgium. However, no harm resulted. 



The difference in the winter colour of the plants was remarkable. 

 As early as the beginning of November the leaves of the Ural 

 plants became almost the colour of the humus soil ; those from 

 Kurland, P^ast Prussia and Brandenburg assumed their winter 

 garb, which was of a less striking character, in the sequence 

 enumerated ; the plants from Hesse and Belgium showed only 

 signs of winter colour, and those from the south of France and 

 Scotland remained green throughout the winter. 



On the loth April 1908, the seedlings were transplanted into a 

 nursery under identical conditions, but strictly separated. It was
