may be withdrawn for incorporation into the museum, or 

 for other purposes. 



7. Extra Collections. Under the agreement with 

 Columbia University, the herbaria designed for under- 

 graduate teaching there and at Barnard College are being 

 formed ; a large portion of the Columbia material has been 

 mounted and delivered to the head of the Department of 

 Botany; a small portion of that intended for Barnard has 

 been mounted and delivered, while a larger portion is in the 

 process of being mounted. 



8. Assistance. The large amount of detail work con- 

 nected with the development of this department has been 

 divided among the several members of the staff and volun- 

 teers. Dr. Rydberg has cared for most of the curatorial 

 work in connection with flowering plants, Professor Under- 

 wood has cared for the ferns and fern-allies and Dr. Howe 

 for the Hepatics and Algae. Mrs. Britton has done much 

 to develop the collection of mosses and to get the specimens 

 in accessible condition for study. Mr. Earle and Professor 

 Underwood have taken special care of the collections of fungi 

 and lichens and Dr. Hollick has had charge of the collection 

 of fossil plants. 



The museum aids, assigned to this department, have per- 

 formed their duties with intelligence and ambition, and the 

 cooperation of other members of the Garden staff has been 

 all that could be desired. 



Respectfully submitted, 



J. K. Small, 

 Curator of the Museums and Herbarium. 

 December 31, 1901.
