JOHNS HOPKINS BOTANISTS AT CINCHONA. 
The residence and laboratory at Cinchona were occupied, 
during June and July, 1910, by a party of six botanists. The 
party consisted of Professor Duncan S. Johnson, Messrs. W. H. 
Brown, A. R. Middleton, L. W. Sharp,and H. H. York, from 
Johns Hopkins University and Professor S. H. Derickson, of 
Lebanon Valley College. Cinchona was also the headquarters, 
for several days in June, of three zodlogists from Johns Hopkins, 
engaged in collecting dragonflies, phosphorescent coleoptera, and 
parasitic copepods. The botanists were engaged in researches 
on the ecology and seed-development of the Piperaceae; on the 
seed-development, germination and relation to the hosts of ten 
or twelve native species of Loranthaceae; on the cytology of 
lichens; on the seed-development of the Orchidaceae and Amaryl- 
lidaceae; and on the reproductive cells of the liverworts. The 
unusual delay in the coming of the rainy season gave abundant 
opportunity for field work. In the studies made at Cinchona 
and the amount of material preserved for study elsewhere, the 
stay at Cinchona proved highly satisfactory to the workers and 
it is believed will prove of importance to science when the re- 
searches there begun are completed. 
During the stay of the Hopkins party on the island, Mr. William 
Harris, Superintendent of Public Gardens and Plantations, was 
helpful to the members in many ways. Mrs. Harris, who was 
stopping at Cinchona, took charge of domestic arrangements at 
the residence and thus left the investigators free to devote them- 
selves entirely to botanical work.
