Waldo L. Sehraitt 
Soil aamples from Belgian Congo Expedition 
At the suggestion of Dr. Fred A. Barclay, a good friend of our former 
Head Curator of Botany, Ellsworth Killip, I saved for biotic assay a 
number of soil samples secured in the course of the Bredin-Congo Expedition. 
I would like to offer them to Or. George W. Mast of the Nepera Qiemical 
Company, Tonkers 2, New York, with which Dr. Barclay is associated. These 
samples are in Washington in the custo<^ of iSp, Willis H. Wheeler of the 
Department of Agriculture, which will release them for such examination 
providing the recipient will exercise tlMs safeguards required of the 
Department for unfumigated soil and plant material. 
Before writing to Dr. Mast I would like to ask your advice regarding 
stipulations that we ini^t care to make regarding 'Uiese samples. Insofar 
as our interest in them is concerned I, personally, think tlmt the 
Institution, for the Bredin Fund, should be entitled to a reasonable share 
of any profits resulting from “discoveries" in these samples. It is well 
understood that an examination of material of this sort can be an expensive 
proposition and, at best, a gamble. Would you care to offer the samples 
to Dr. Mast or should I? 
A draft of a letter that might be sent him is attached.
