Mr. I. C. Williams, 



Deputy Commissioner of Forestry, 

 Harrisburg, Pa. 



Dear Mr. Williams: In reply to your letter of April 18, I 

 can give you the following report: 



The fungus on your specimen made a small growth as I at 

 first reported to you. After however, it had started to produce 

 a small number of picnidia it ceased to grow. I then began 

 again, and found that I could cause the spores to germinate. 

 They in turn made but a small growth, and afterward Avere 

 imable to produce any fruiting picnidia. A small part of the 

 bark which I removed from your specimen was put in a damp 

 chamber. I was unable to get any growth at all from this. This 

 shows that the specimen has almost lost life. This loss of 

 vitality may be due to the Penicillium, a fungus which has 

 covered the surface of this specimen. I will return the speci- 

 men in the bottle to you at once. 



Very truly yours, 

 (Signed) CAROLINE RUMBOLD."
