Dear Prof. Collins: 
I have your card of December 8, requesting culture of nitrogen¬ 
fixing bacteria, and I have placed your request with the Office of 
Plant Physiology and Pathology. I am sure that the culture material 
will be ready for you when you desire it. It would be well to indi¬ 
cate the kinds of plants which you wish to inoculate since there is 
a special organism for each group of legumes. 
I will send a copy of the moss paper with my best compliments. 
Yours sincerely, 
* 
Physiologist in Charge.
