REPORT OF CURATOR OF PLANTS FOR 1927 

 Dr. C. Stuart Gaoer, Director. 



Sir: I submit herewith my annual report for the year 1927. 



Research work was continued on the flora and vegetation of 

 Long Island, as outlined in the record of research activities else- 



With your permission, and with a leave of absence from the 

 Garden. I took charge of the courses in iV.ianv at the new MTgany 

 School of Natural History, Allegany State Park. N. Y., during 

 July and August. Lectures and field trips were combined in a 

 study of the Beech-Birch- Maple forests, and other vegetation 

 types. In addition to this class work. I wrote a report entitled 

 Vegetation of Allegany State Park which will be published as a 

 Handbook of the New York State Museum, for distribution to 

 the public next summer. This will also appear as Brooklyn 

 Botanic Garden Contribution No. 54. 



The Agricultural Experiment Station at Cornell University is- 

 sued as Bulletin 458, my paper on the Climate of Long Island. 

 This is part of the Forests of Long Island and. with the sections 

 on sods, succession, forest types, etc.. will comprise Part two of 

 Volume two of the Botanic Garden Memoirs, the first part of 

 which is the Vegetation of Montauk. It was reprinted as Brook- 

 lyn Botanic Garden Contribution No. 50. 



In cooperation with Dr. Reed and Mr. Free, I have made pH 

 determinations and moisture-holding-capacity tests for the soils 

 on 18 beds in the Iris Test Garden, each of which is being treated 

 differently as to fertilizers, etc. The plan involves making later 

 tests from the same beds to determine the effects of the diverse 

 treatment upon the soils, and. of course upon the iris plants. 



In June the long delayed publication of Volume three of the 

 Memoirs of the Garden was accomplished. This completes a 

 study begun in 192 1 with Major Barrington Moore. The paper 

 is entitled Vegetation of Mount Desert Island, Maine, and its 

 Environment, and comprises 151 pages, 14 tables, 27 text figures, 

 and a colored vegetation map. 



In December I visited the herbaria of Cornell University, the
