A great and unique fight has been carried 



Fighting on for 8 years in all the pineries of Prussia 



Fungus (nearly 4 million acres) to get rid of the 



infection by Trametes pini on Scotch pine. 



Over 200 million cubic feet of infected wood has been cut and often 



the whole management of revirs has been disturbed thereby. 



Dr. Moeller, at whose instance this war was begun, reports on 



results. Tables give details. Some $120,000 extra expenses 



were incurred in designating and marking the infested trees and 



in removing fruit-bodies and painting the scars with insect lime. 



Out of 365 revirs, only 97 are not yet entirely free of fruit-bodies, 



and it is estimated that nearly 85 million cubic feet more of 



infested material remains standing. 



The breaking out of the "consols" and painting the scar with 

 insect lime on trees that cannot at once be removed is done to 

 reduce spore distribution and retard formation of new fruit-bodies. 

 The latter do not reappear on the painted scars. The eflEicacy of 

 these measures is attested. Fruit-bodies occur usually from 10 

 to 20 years after infestation, so that the infection does not become 

 visible early, and hence much of the new fruit -bodies had their 

 origin before the fight began. 



Moeller considers the final victory absolutely sure, if the meas- 

 ures are continued, the strictly localized occtirrence of its only 

 fruit-body permitting such expectation. 



Investigations by Moeller lead him to side with Hartig in believ- 

 ing the Trametes on spruce as identical with the pine fungus, 

 although an absolute decision is still withheld.

The general method of timber extraction 



Mahogany on the Gold Coast is to haul the logs by 



Borers of manual labor to the nearest stream, down 



the Gold Coast which they are floated to the mouth and 



there rafted. During last August, when the 



niunber of logs were greatest, there was an unusually small rainfall 



and insufficient water to carry the logs to the rafting points 



beyond the sand bars at the mouths of the rivers. 



Dtiring the last seven years stranded timbers have shown signs 

 of attack from borers belonging to an undescribed species of
