‘‘NortH AMERICAN Fiora.” Our collections of these 
plants have been greatly increased in value and importance 
through the studies of these gentlemen. 
Mr. C. B. Robinson, a graduate student of Columbia Uni- 
versity, was granted a scholarship for three months to aid him 
in the completion of his monograph of the North American 
stone-worts (Characeae). The results of this study were pub- 
lished in our BULLETIN and constituted Mr. Robinson’s dis- 
sertation for his degree of Doctor of Philosophy, which was 
awarded him by the University at its last commencement. 
His studies were largely based on the great collection of 
Characeae presented to the Garden some years ago by the 
late Dr. Timothy F. Allen, and this collection was materially 
improved and increased in the course of Dr. Robinson’s 
work ; in July he was appointed an Assistant Curator. 
Professor T. C. Frye, of the University of the state of 
Washington, held a scholarship during the months of July 
and August, during which time he was occupied in an inves- 
gation of the mosses of that state and contributed many speci- 
mens of these plants to our herbarium. 
Professor Raymond H. Pond, of Northwestern University, 
is at present in residence as a scholar engaged in investiga- 
tions in plant physiology under the direction of Dr. Gager. 
He has held a scholarship for three months. 
Miss Mary Perle Anderson is also in residence, having 
held a scholarship for three months, engaged in an investiga- 
tion of the ferns of Japan under the direction of Professor 
Underwood. 
Preservation of Native Plants 
The income of the fund of $3,000 presented to the Garden 
by Misses Caroline and Olivia Phelps Stokes for the preser- 
vation of native plants, has for the most part been allowed 
to accumulate during the year, with the plan of utilizing 
it during 1907, together with this year’s income, in pro- 
viding the means for delivering a series of lectures in New 
York and other cities. One circular advocating the reserva- 
tion of natural woodlands and the desirability of protecting
