A beginning was made in the installation of a series of 

 large drawings to illustrate the plant, or a portion of the 

 plant, from which the various plant products exhibited 

 in this museum are derived. Many drawings of a similar 

 character of North American trees were made preparatory 

 to the further development of the collection of North 

 American dendrology. (For details see report of the Cura- 

 tor of the Economic Collections.) 



The Systematic Museum, consisting of the Synoptic 

 Collection, the Local Flora, and the Microscope Exhibit, 

 was increased by the interpolation of miscellaneous speci- 

 mens or improved by the replacement of individual speci- 

 mens in the different series. Much valuable material thus 

 added was derived from the results of the several recent 

 exploring expeditions maintained by the Garden. 



A plan developed early in the year for the display of 

 large photographs in the spaces between the windows of 

 the halls and wings of this museum was carried forward 

 as far as possible. The photographs are made, the card- 

 mounts and frames are in hand, and a large part of the 

 label copy is in the hands of the printer. It is planned 

 to install this new element of the Systematic Museum 

 early next year. 



Herbaria 



The general herbarium was enriched by material from 

 many parts of the globe, but especially from America 

 north of the Isthmus of Panama and from the Philippine 

 Islands. 



About 50,000 herbarium sheets, containing fully 70,000 

 specimens, were mounted and incorporated in the her- 

 barium cases. These accessions represent, in addition 

 to various minor collections and many miscellaneous speci- 

 mens acquired during this and previous years, the results 

 of exploration in the Bahamas, Cuba, Santo Domingo, and 

 Panama, as well as other portions of the North American 

 mainland, and the American specimens from the Otto 

 Kuntze Herbarium, and a large part of both the Mitten
