Bear Miss Bay: 
I inquired of Professor Vinal about the article 
that you asked me about a week ago. It seems that he never 
had any reprints of the article and he does not know where 
any extra copies of the magazine can be obtained, so I 
borrowed his own copy and have had it typewritten. I am 
sending you a carbon of this, which may be of some use to 
you until such time as you ere able to get hold of an 
original ee-rrg. 
Very truly, 
J. FRANKLIN COLLITS, 
Forest Pathologist.
