Mr. Walter Deane 
9 Brewster Street, Cambridge, Mass., 
My dear Mr. Deane, 
I am glad to learn that the duplicates 
recently sent you by the Museum were so satisfactory. This consignment 
does not interfere in any way with your receiving a set of our proposed 
distribution of North American Violaceae. We have a running account with 
you in the matter of general duplicates, and are always glad to receive 
whatever you may have for distribution. 
The labels are now being printed for the first decade of the violets, 
and I hope they will be ready to send out very shortly. 
Have you examined my recent revision of Achillea? I shall be glad 
to receive material of A. asplenifolia, if you come across it in some old 
garden. 
Yours very sincerely. 
Assistant Curator, Division of Plahts.
