PLANT CONSERVATION 
Not a few inquiries regarding plant conservation have been re- 
ceived and answered during the year by letter and by means of 
appropriate Leaflets. 
In June a considerable number o 
Reh 
mature Hartstongue plants 
(Scolopendrium vulgare), raised in the Propagating House by 
Joseph Bass, were sent to interested people, who defrayed the cost 
of packing and postage. 
Respectfully submitted, 
Ratpu C. BENEDICT, 
Resident Investigator (Ferns). 

REPORT OF “THE RESIDENT INVESTIGATOR 
(ECONOMIC PLANTS) FOR 1935 
Dr. C. Stuart GAGER, DIRECTOR: 
Sir: | submit herewith a report of the activities of the Resident 
Investigator for Economic Plants during 1935. A course in [co- 
nomic Plants was offered during the current year. This work was 
supplemented by lantern slides, the investigator’s collection of 
economic plant products, and the living species available in the 
Botanic Garden Conservatories. 
For display during the Twenty-fifth Anniversary Week in com- 
memoration of the establishment of the Brooklyn Botanic Garden, 
a collection of the wild and cultivated species and varieties of the 
genus Coffea Linn. was organized. In addition to the living coffee 
plants in the central plant house, herbarium specimens were ob- 
tained from all of the coffee-producing areas of the world. This 
was made possible by the generous assistance of the British Co- 
lonial governments of eastern and western Africa and India. The 
Brazilian and Colombian agricultural departments were also grati- 
fyingly cooperative. A special exhibit of the fruits and seeds 
(beans) from the various species and geographical areas and in 
the several stages of their commercial preparation was presented.
