Spruce seed from Vestre Palsgaard, Jutland, compartment 74, a 

 very well grown wood 80 years old, 30 35 metres high; from 

 weighing 5x100 seeds: 7.17 grams per 1000 seeds. 



Spruce seed from trees about 35 years old in Fraeer Purker, 

 Lindenborg, in Jutland; from weighing 5x100 seeds: 4.37 grams. 



Spruce seed from Rold Skov, Jutland; 2x100 seed: 8.90 grams 

 per 1000 seed. 



The trees in Vestre Palsgaard and Rold Skov may therefore be- 

 long to a Mid-European strain, those in Fraeer Purker to a Scan- 

 dinavian one. 



The germinating capacity appeared to be good. An exactly simi- 

 lar result for several Pine seeds will be discussed when referring 

 to that species. 



With the three other species of spruce those from the Hi- 

 malayas, the Balkans and the Caucasus I have hitherto had 

 little to do; though I think the CAUCASIAN SPRUCE, Picea ori- 

 entalis a very valuable tree, well worthy of more extended cul- 

 tivation as soon as cheaper seed can be obtained. The real value 

 of the seed is generally good: in the three last seasons it was as 

 follows :

THE PINES. PINUS. 



The four allied species PINUS AUSTRIACA, P. CALABRICA, 

 P. LARICIO and P. PALLASIANA may well be discussed together, 

 for in the seed tests they differ from one another only in the size 

 of the seeds. The mean seed weights amounted to 18.8, (21 samples), 

 17.1 (6 samples), 14.8 (22 samples), and 23.7 (4 samples) respectively. 



The germinating capacity is often first rate, but also often very 

 moderate, because the seed quickly falls in germination power if 

 stored from year to year. In 1909 10 the seed of the Austrian 

 Pine was particularly good, I therefore caused the germinating 

 capacity of the same lot to be tested in the three successive years 

 and obtained the following results:
