that blooming of pine and spruce is less vigorous in trees which 

 grow in stands than in trees grown in the open. Birch and beech 

 developed few seed and acorns. Beech, Carpinus and Fraxinus 

 did not flower and did not produce fruit. Of all other broadleaf 

 species only elm gave a good crop of seed in places. Siberian 

 larch, Japanese larch, and silver fir flowered and bore cones in a 

 few places, and the silver fir which is an imported species in 

 Sweden gave a fair crop of well developed cones. 



The extent to which the Forests were provided with seed from 

 their own trees was as follows :

Although the statistical data regarding the production of seed 

 in 1909-10 collected by Schotte are well worked up, his deductions 

 must be taken with considerable caution. They must be con- 

 sidered merely as giving the relative, qualitative seed production 

 as ocular statistical method for determining the seed production 

 has proved to be not very reliable.

Dr. Schwappach reports the result of ex- 



Influence periments carried on at Eberswalde during 



of 50 years ( !), more carefully during the last

The results are given in detail, tabulated 

 and discussed. Former reports on these investigations are cited, 

 and confirmed or modified. The experiments were made in 

 stands of Scotch Pine, Spruce, and Beech. For each species, the
