4. Rock Carder, and Alpine Day, May 2±, ( iuide : Mr. Montague. 



5. /r/.y £>«y, June 7. Guide: Dr. George M. Reed. 



At each of these " Days " a preliminary talk of 10 to 1 5 minutes' 



length was given in the Laboratory Ihiildiiig, and this was fol- 

 lowed by inspection of the flowers on the grounds. Various ques- 

 tions relating to the culture and selection of suitable varieties of 

 the plants in question were discussed informally. 



A preliminary announcement of the plan was sent in March to 

 each member of the Garden, with a tentative schedule of dates for 

 the various flower displays. Since such dates must depend on the 

 progress of the season, postcard announcements were sent out 

 a few davs before each occasion, definitely fixing the date. 



Bureau of Information 



Requests from visitors, and by letter and telephone, for in- 

 formation of ever) com vabli oil 1 -latin; t< plants, are con- 

 tinually increasing; and anr • a ling- portion of my time is oc- 

 cupied with mswerin^ tin < [ue don 1 r • -1 thai mention of the 

 fact should be made in this place. Much of the information could 

 not be given without the cooperation of the Staff, in particular of 

 the Librarian, the Curator of Plants, and the Horticulturist. 



Editorial Work, etc. 



I have continued to serve as Editor for the following pe- 

 riodicals : 



1. Plant section of General Biology in Aiohxjical Abstracts. 



2. American Journal of Botany. 



3. Brooklyn I'olanic Garden Leaflets. 



I have also served, for the fourth consecutive year, as secretary 

 of the Torrey Botanical Club. 



In a separate report (p. ) I have given an account of the 



research work 1 have been able to carry on during the year. On 



account of the increasing demands of other duties on my time, 



there has been little opportunity for independent work of this sort. 



Respectfully submitted, 



Arthur Harmount Graves, 

 Curator of Public Instruction.
