Dear Mr, Schmitt: 
Thank you very much for your letter of 
November 25, 1955, in which you express a desire 
to have the du Pont Company test soil samples 
collected on your recent Belgian Congo Expedition, 
The du Pont Company will be happy to 
accept and test these samples with the understanding 
that the Smithsonian Institution, and other interested 
parties, waive all rights with respect to the soil 
samples and any useful products which may result from 
them. Your letter indicates that such an arrangement 
would be a satisfactory basis on which to proceed. 
Accordingly, it is requested that the samples. 
along with all future correspondence, be sent to Dr, 
Dale E. Wolf, E. I, du Pont de Nemours & Company, 
Grasselli Chemicals Department, Building 268, Experi 
mental Station, Wilmington, Delaware, It would be 
appreciated if you would send a copy of previous 
correspondence on these samples to Dr, Wolf, 
Thank you for your consideration in this 
matter 
Yours very truly.
