montana gallica is larger than that of the common many-stem- 

 med form, or at least was so, for the weight seems to be decrea- 

 sing, as the following figures show: 



1901 02 Danish seed from Feldborg in Jutland 8.5 grams 



190304 8.2 



1905 06 8.59 



1906 07 9.46 



1907 08 8.7 



1908 09 7.54 



191011 Stoholm 7.2 



The mean weight is 8.31 grams. 



In the season 1911 12, a small sample of the French Mountain 

 Pine seed collected in the Pyrenaean mountains was submitted for 

 testing by The Danish Heath Cultivation Society and gave the 

 following result: Seed weight 7.6 grams, Purity 93.3 %, Germination 

 after 5 days 2%, 10 days 37%, 20 days 55 (+21)%. The low ger- 

 minating energy and the low seed weight suggest that the seed 

 was more than a year old, or that it was obtained from cones 

 pulled in an unripe condition. 



The falling off in weight of the seed harvested in Danmark is 

 remarkable. The plantations in Feldborg and Stoholm are 25 30 

 years old and originated in seed which was obtained partly from 

 the Pyrenees, and partly from Briancon in the Department of Hau- 

 tes Alpes. The decreasing size of the seed may perhaps indicate a 

 hybridization with the many-stemmed form of P. montana, which 

 occurs abundantly everywhere in Jutland. 



Of the CREEPING MOUNTAIN PINE PINUS MONTANA 

 PUMILIO I have only had two samples during the whole time, 

 which gave the following results:

190203 Seed from Switzerland 6.0 73 79 89 (+4) 



191112 Riesengebirge 5.1 9 83 88 (+4) 



Whether the Swiss seed is of the creeping form, is perhaps 

 doubtful. On the other hand, that from the ridge of the Riesenge- 

 birge Hohe Schneekoppe , which I received from the forest 

 officers in that district, after many requests made from time to 

 time for a number of years, should be genuine. The small cones
