charge of the laboratory and engaged in a variety of ecological 

 and morphological studies. * 



1906. Professor D. S. Johnson, of Johns Hopkins University, 

 accompanied by two graduate students, spent some weeks at Cin- 

 chona continuing his morphological and embryological studies, 

 especially in the Piperaceae and the Chloranthaceae. Of his stu- 

 dents, Mr. I. F. Lewis made a study of the fresh water algae of 

 the Blue Mountain region, collecting about fifty species represent- 

 ing thirty genera, of which sixteen had not hitherto been reported 

 from the island ; and Mr. W. D. Hoyt made a study of the pro- 

 thallia of the Hymenophyllaceae and Psilotum. 



Later in the season Professor A. W. Evans, of Yale Univer- 

 sity, made further studies of the hepaticae, and his assistant Mr. 

 George E. Nichols made a study of the distribution of the mosses 

 of the region. Both these gentlemen were in residence at Cin- 

 chona when Dr. Britton accompanied by Mrs. Britton and Miss 

 Delia W. Marble and by the present writer made a short visit to 

 Cinchona, of which Dr. Britton has given a fuller account in the 

 present number of the Journal. Of the sixteen botanical stu- 

 dents that have made use of the laboratory at Cinchona, six have 

 already made a second visit. 



Already the success of the laboratory at Cinchona has justi- 

 fied the wisdom of the selection of this site for a laboratory. In 

 leasing the grounds and buildings the Garden has done all that 

 could be reasonably expected of a single institution. A well- 

 ordered tropical laboratory is open to American botanists, easily 

 accessible, delightful as a place of residence, surrounded by a 

 most magnificent tropical flora offering problems without limit, 

 and a wealth of botanical experience is now attainable by Amer- 



discomforts and dangers common to tropical lands. If Amer- 

 ican botanists and botanical teachers really want the advantages 

 of a tropical botanical laboratory, they now have it in their power 

 to cooperate to make Cinchona as profitable a botanical Mecca 

 as the famous old-world laboratory at Buitenzorg.
