The Botanical Section. 



The Botanical Section reports that its meetings have been held regu- 

 larly during the year, with a fair attendance of members. 



A number of interesting and valuable communications have been 

 made, many of which have been repeated before the general meetings 



of the Academy. 



The Conservator reports that during the year considerable progress 

 has been made on the work of arranging the collections. Special effort 

 being directed to put in order the unmounted material which has accu- 

 mulated in recent years, resulting in the poisoning of about 15,000 

 sheets, which have been mounted, numbered, catalogued and dis- 

 tributed in their proper places through the Herbarium. 



Early in the summer new cases were erected in the center of the 

 north room on the library floor. They are so arranged that their 

 tops form two tables, each eighteen feet long by three feet broad. 



This has added twenty-eight closets of twelve compartments each 

 to the Herbarium space, which has resulted in reheving the overcrowded 

 condition of a considerable portion of the collection. 



During the year all of the Authophytes have been rearranged to 

 conform to the family sequence of Engler and Prantl, commencing m 

 the new cases above referred to, sufficient space being left to allow for 

 additions to the families arranged in this room for some time to come 

 The cases in the south room are, however, still much crowded, and 

 will require additional cases for their relief. 



Dr. Krout began, during the summer, the arrangement of the 

 Mosses and Hepatics in the Academy's Herbarium. Thus far about 

 1 500 specimens having been put into pockets and mounted on 

 sheets; these have been placed in cases in the south gallery room.
