Letter from Thomas Gold to Professor Daniel Fivel, Department of Physics, university fo Maryland, College Park, Maryland Is returning the request for Aspen housing reservation during the summer. Unfortunaetly there are several conflicting demands on his time, and it appears that he cannot now come to Aspen for more than the two weeks August 16 to August 28. He hopes it is still possible at this time to reserve him a small apartment for that period, and he apologizes for any complication this produces. 4 May 1971
