FOREST COMMISSIONERS REPORT. I39 



free of the disease than were found to be infected. The wild 

 plants are often found growing in thick mats over the forest 

 floor. In some cases they all appeared to be infected, while in 

 other cases, having practically identical environmental condi- 

 tions, only a very small per cent of them would show the dis- 

 ease. A single infected plant has often been found in the 

 center of thick growths of plants which did not show the 

 disease. Healthy plants are often found in moist shaded places 

 while the plants of the same species growing in a pasture, field, 

 or dry roadside would be heavily infected. The reverse of this 

 statement is found to be true also. 



Since plants growing under many different sets of field con- 

 ditions have apparently shown that the attacks of the disease 

 does not follow, exclusively, any set of conditions, it appears 

 to me that the climate in Maine is favorable most anywhere for 

 the development of the disease on gooseberries and currants. 



Infected pines were found at Bar Harbor, Lewiston, Bath, 

 Riverton Park and Kittery. Many of the infections were on 

 young trees, some of which had already been killed, others were 

 dying from the disease, while others were only attacked on 

 small branches. At Riverton Park and Kittery many large 

 trees showed the disease on lateral and terminal branches. 

 Some of these branches were just dead, others had been dead 

 for some time, while others were turning yellow at the ends 

 (foliage).
