Treatment. 



The treatment, therefore, is to destroy all pines having the 

 disease as fast as it shows itself on them, and to keep all cur- 

 rants and gooseberries so far away from pines that the disease 

 cannot carry from one to the other in either direction. The 

 distance apart to insure this is not positively known, but it is 

 believed that one-third of a mile or 500 yards should be suffi- 

 cient. 



To find the disease, look on the pines from the first of May 

 till the end of June. 



On the currants it shows from the middle of July till the 

 leaves drop in the fall. 



Currants free in July and August may catch the disease 

 during the summer from others, and first show it in September. 

 Black currants are attacked more generally than other kinds 

 of currants or gooseberries."
