Preservation of Native Plants 
Part of the income of the fund of $3,000 established by the 
Misses Caroline and Olivia E. Phelps Stokes for the preser- 
vation of native plants has been expended in the printing of 
circulars, and part in the payment of prizes for essays. It is 
already apparent that greater attention is being paid to the 
care of natural woodlands than previously, and there is no 
doubt that the existence of this fund and the expenditure of 
its income are having a good effect. 
Administrative 
The resignation of Dr. D. T. MacDougal as Assistant 
Director to accept the position of Director of Botanical Re- 
search in the Carnegie Institution of Washington, has made 
a reorganization of the administrative work necessary. Dur- 
ing the year I gradually increased the duties of Mr. Percy 
Wilson, Administrative Assistant, under the policy advocated 
by the Scientific Directors of relieving me of as much detailed 
executive work as should prove to be practicable, and under 
the further advice of the Scientific Directors, I have appointed 
Dr. William A. Murrill as First Assistant, to take general 
charge of the Garden at times when I should be absent. 
Reports Appended 
I submit also reports by the Assistant Director, the Curator 
of the Museums and Herbarium, the Curator of the Economic 
Collections, the Librarian, the Head Gardener, the Superin- 
tendent of Buildings and Grounds, and a schedule of expendi- 
tures under appropriations made by the Board of Managers. 
Respectfully submitted, 
N. L. Britton, 
Director-in-Chiep.
