The Conservator spent about a month in the Bermudas during 
February and March of the present year, by the aid of a grant from 
the Esther Hermann Research Fund of the New York Academy of 
Sciences, when collections of over S00 herbarium specimens were 
made. During the summer, through the liberality of Mrs. Charles 
Schaffer and Miss Mary W. Adams, he was enabled to make further 
studies of the flora of the Canadian Rocky Mountains, ten weeks 
being spent in the region about the headwaters of the Saskatchewan 
and Athabasca Rivers, when collections of more than 3,000 herbarium 
specimens were made, including a number of probably new species. 
Owing to the pressure of other duties it has not been possible to yet 
give this collection critical study. 
The activity manifested in previous years by the members of the 
Philadelphia Botanical Club has been maintained during the past 
season, more than 2,000 specimens being added to the local herbarium, 
including a number of species not previously recorded as occurring 
in the region. Air. Samuel S. Van Pelt has continued his valuable 
services during the year as Curator of this important and rapidly 
growing section of the herbarium. 
At the annual meeting of the Section, the following officers were 
elected for the year: 
Director, ...... Benjamin H. Smith. 
Vice-Director , ..... Joseph Crawford. 
Recorder, ...... Charles S. Williamson. 
Treasurer and Conservator, . . . Stewardson Brown. 
Respectfully submitted,
