Wadleigh High School, remained during the same period, making 

 a study of the embryology of certain Loranthaceae.* 



1905. Clara E. Cummings, professor of botany in Wellesley, 

 spent several weeks investigating the lichen-flora of the region. 

 She was accompanied for a part of her stay by Martha E. Merrow, 

 botanist of the Rhode Island Agricultural College. Later in the 

 season and continuing until the late spring of 1906, Dr. Forrest 

 Shreve, of Woman's College, Baltimore, was in charge of the 

 Laboratory and engaged in a variety of ecological and 

 morphological studies. f 



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 Piperaceas 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 repre- 

 senting thirty genera, of which sixteen had not hitherto been 

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

 the prothallia of the Hymenophyllaceae and Psilotum. 



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

 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 Cinchona 

 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 full account in the present num- 

 ber of the Journal. Of the sixteen botanical students 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 justified 

 the wisdom of the selection of this site for a laboratory. In leas- 

 ing 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 bota- 

 nists, easily accessible, delightful as a place of residence, sur- 

 rounded by a most magnificent tropical flora offering problems 

 without limit, and a wealth of botanical experience is now attain- 

 able by American students at a minimum expense, unattended by 

 the ordinary discomforts and dangers common to tropical lands. 

 If American botanists and botanical teachers really want the ad- 

 vantages of a tropical botanical laboratory, they now have it in 

 their power to cooperate to make Cinchona as profitable a botani- 

 cal Mecca as the famous old world laboratory at Buitenzorg.
