Mr. Harold St.John, 
Gray Herbarium, 
Cambridge,Mass, 
Dear St. John:- 
Today I received a letter in reply to my inquiry 
of our fellow H.E.B.C. member, H, E. Whipple, regarding the 
"Mill Pond", Lonsdale, R,I. He says the Mill Pond referred 
to at the time the Elodea was collected was, in all probability, 
the pond in the Blaekstone river made by the dam at Lonsdale. 
This would be the one partly in Cumberland and partly in Lincoln, 
so, under the circumstances, your designation or "Mill Pond, 
Lonsdale" (Rhod. 22:28, Eeb, 1920) is safer than either town 
name. 
Mr. Whipple apologizes for his delay in replying and says 
that at the time I wrote him he was in the hospital recovering 
from a severe operation, and only recently has recovered suf¬ 
ficiently to reply 
Sincerely
