1908.] NATURAL SCIENCES OF PHILADELPHIA. 63Q 



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 800 herbarium specimens were 

 made. During the summer, through the hberality 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. 

 Owdng to the pressure of other duties it has not been possible to j^et 

 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. Mr. Samuel S. Van Pelt has continued his valuable 

 services during the year as Curator of this important and rapidly 

 growing section of the herbarium.
