Among the present day practices of Ger- 



Results man foresters which are open to criticism 



of stands the departure from the dense seed- 



Wide Spacing. ling stands of the early nineteenth century. 



This tendency to starting out wath fewer 

 individuals to the acre is noticeable, both in planting and in 

 sowing — in sowing especially, where but about one-fourth the 

 amount of seed is used as was once the rule. Practical reasons 

 for such a change are not to be found, says Frombling, and the 

 advantages which appear to have been expected from it appear 

 doubtful. The lessened cost will be more than offset by the 

 cost of replacing fail spots and in the lessening of the yield from 

 the earlier thinnings, while the hope of producing more vigorous 

 plants by sparing them the struggle with their neighbors is left 

 without foundation in that in actuality weaker individuals are 

 permitted to occupy the ground longer than nature would allow 

 were competition a little more intense. Throughout, this sparse 

 planting is shown to be unnatural, for when natural regeneration 

 is resorted to the success of the plan is largely judged b}^ the 

 density of the young growth secured. It is but just to apply 

 the same criterion to the results of sowing and planting.

Following Dr. MoUer's example (see vol. 

 Loss III, p. 47), Dr. Hemman has made an in- 



by vestigation into the loss of value b}^ Red 



Red Rot Rot in Scotch Pine, in two fellings com- 



prising somewhat over 32,000 cubic feet. 

 He classifies the degree of damage in a table giving the loss 

 for different per cents of diseased trees, which may be of more 

 general interest :
