Two samples from DANMARK from Viborg and Feldborg in 

 Jutland weighed 7.47 and 7.76 grams. 



Nine samples from Norway-Sweden gave a mean weight of 

 5.3 grams. Three samples from Southern Sweden weighed 5.47, 6.0 

 and 6.02; three from East Norway 5.26, 5.38 and 5.56, one from 

 West Norway from Vos 5.16, and on from Northland in Norway 

 4.09 grams. 



One Finland sample: 4.82 grams. 



The weight results for Pine seeds will be more fully set forth 

 later. As time went on, these observations of the first year, now 

 24 years old, were further confirmed. As is to be seen from the 

 attached table, the highest average seed weight for 57 Mid-Euro- 

 pean Spruce samples was 9.68, the lowest 6.73. Mean weight 8.06 

 grams. 



The highest seed weight for Danish seed 8.87, the lowest 6.84, 

 mean 7.97. 



Finland seed, highest 5.5, lowest 3.97, mean 4.97. Norwegian and 

 Swedish seed, highest 6.02, lowest 5.07, mean 5.60. 



Norwegian Northland seed, highest 5.16, lowest 4.10, mean 4.74. 



A sample from the Urals in 1908 weighed 4.56* 



The seed of the SIBERIAN SPRUCE PICEA OBOVATA 

 shows in the highest case 5.76, in the lowest, 4.45, mean 4.86 grams, 

 and seems to indicate the possibility that this spruce is only a form 

 which most closely approaches the Finland-Scandinavian spruce. 



In order to determine if this higher or lower seed weight was 

 hereditary when the trees are grown in Danmark, and the weight 

 of the seeds in consequence could perhaps be used to determine 

 if our old spruce woods are of Scandinavian or Mid-European 

 origin, I sought carefully for several years to obtain cones with 

 good, fully ripened seeds from two old woods in the forests of 

 Vestre-Palsgaard and Rold Skov in Jutland, which according to 

 tradition were raised from Norwegian seed. In Jutland, however, 

 the flowers of the spruce are often destroyed by late frosts, so 

 that my object was only attained for the first time in 1911. The 

 weight determinations, according to the certificates Nos 75931 and 

 75932 of the Dansk Fr6kontrol, gave the following results: 



* Later CIESLAR has demonstrated that the same fall in the weight of Spruce seeds is shown also 

 with increased elevation, such as in the mountains. Seed from high elevations is considerably smaller 

 than that from the lowlands. Professor Dr. A. Cieslar: Die Erblichkeit des ZuwachsvermSgens bei den 

 Waldbaumen (Centralblatt far das gesamte Forstwesen 1895).
