Dear Dr* Schmitt ! 
Since your last contact with Dr, Wolf early this 
year, he has changed positions and your letter of August 8, 
along with your other correspondence , has been referred to 
me since I am directly involved -with soil screening. Me 
are in a position to handle the soil samples and will be 
glad to receive than. 
As with the African soil samples, the du Pont 
Company will be happy to test and accept these new soils 
with the understanding that the Smithsonian Institution 
and all other interested parties waive all rights with 
respect to the samples and any useful products which may 
result fro® them. As you indicated in your letter, such 
an arrangement appears once more to be a satisfactory 
basis on which to proceed* 
Thank you very much. 
Very truly yours,
