Dear Steve, 
I have decided to accept your offer to permit us to copy the 
Merrill compilation of Elmer's field notes, 7037-18477a. It 
probably would be simplest if you could loan the set to me. I will 
arrange to have it copied here and return your set. Should this be 
done as an interlibrary loan? 
As ever, 
Da WE
