4. Uses of the Herbaria. These collections have con- 

 stantly been used by members of the Garden staff, members 

 of the staff of the Department of Botany of Columbia Uni- 

 versity, and the students of both institutions, for research 

 work, and special investigations, for museum work, for the 

 comparison of specimens generally, and in connection with 

 the development of the Garden conservatories and Planta- 

 tions. They have also been used by responsible persons not 

 connected with either institution by permission of the Director- 

 in-chief. Many officers and students of other institutions both 

 in this country and abroad have consulted the collections. 



5. Special Collections. At the request of the Professor 

 of Botany of Columbia University, we have undertaken the 

 preparation of two teaching herbaria, one for the Department 

 of Botany at Columbia and one for that of Barnard College. 

 These collections are to take the place of the herbaria of both 

 those institutions now in deposit at the Garden. Many spec- 

 imens have been selected from our duplicates and reserved 

 for these collections. 



6. Assistance. The museum aids assigned to my de- 

 partment have performed their duties faithfully, and the 

 hearty cooperation of other members of the staff has aided 

 much in advancing the work of this department. 



Dr. Rydberg, Assistant Curator, has carried on the practical 

 work of the herbarium. Special and noteworthy aid has 

 been received from Mrs. N. L. Britton and Prof. L. M. 

 Underwood both in the direction and prosecution of mechan- 

 ical work, in connection with the groups of plants in which 

 they are respectively interested. Mrs. Britton as heretofore, 

 has taken charge of the mounting and distribution of the 

 specimens of mosses, while Professor Underwood has acted 

 in the same capacity during the mounting and distribution of 

 the specimens from the Ellis fungus herbarium. 



Respectfully submitted, 



T. K. Small, 

 Curator of the Museums and Herbarium.
