My dear Colonel Sherrill: 
I happened to see in yesterday's paper a 
note to the effect that you regard the Piney Branch Valley 
so far desecrated by building and grading enterprises as 
to be beyond utilization as a part of the part system. 
Possibly you are not aware of the fact 
that Piney Branch was the resort of Indian tribes and that 
the ancient quarries there are among the most interesting 
evidences of occupations by Indian tribes east of the 
♦ 
mountains. 
To me this old quarry in the centre of the 
capital city of the nation is a sacred spot. My dis¬ 
coveries there have done more to clear up the story of 
man in America than any single piece- of research within 
the United States. I beg therefore to suggest that 
some day when spring opens you will let me Join you on 
a visit to this site which has not yet been tooiehed by 
the ruthless invaders. 
Sincerely yours, 
Director. 
Lieut.-Colonel Clarence Sherrill, 
Rock Creek & Potomac Parkway Commission,
