Phanerogamic Herbarium 
An estimate of the number of specimens in the collection, 
counting flowering plants, ferns and fern allies only, based on 
actual counts of many pigeonholes in the herbarium and aver- 
aging the balance, shows the following :

The chief additions, beyond my own collections on Long Is- 
land, Slide Mountain and at Mt. Washington, were as follows: 
Roland M. Harper—57 specimens from Long Island as a gift ; 
Canton Christian College—638 specimens from China, pur- 
chased; Walter Fischer—284 specimens from the Argentine, 
Adeehasede C. A. Schwarze—78 specimens of Hadsted’s North 
American Weeds as a gift; Miss Daisy Levy—8oo miscellaneous 
specimens as a gift. During the year 2,417 specimens were 
mounted and these are included in the count of the collections 
summarized above. 
Personal Activities 
A visit, for the first time, to Gardiner’s Island, during my field 
work on Long Island shows that any account of the vegetation 
of Long Island will be incomplete without further study of it. 
This unique island, large parts of which have been undisturbed 
since about 1650, has such primeval forests upon it that without 
careful study of them one can get no true idea of the vegetation 
or its development on Long Island. At least one more season’s 
work at the eastern end of Long Island is, therefore, necessary 
before the volume on the vegetation of Long Island can be ready 
for the press. 
Collections during the season of 1918 at the summit of Mt. 
Washington and the Slide Mountain in the Catskills, have sug- 
gested a continuation of such collections, with the addition of 
Mt. Marcy in the Adirondacks. The correlation of these studies 
with problems in. ecology, and with the advantage of collecting
