Building of ‘Coral’ Reefs.” Dr. Howe’s researches during 
the year have been concerned chiefly with a large collection 
of marine algae from Peru, the results of which are now 
nearly ready for publication. He has continued to act as 
an associate editor of the publications of the Torrey 
Botanical Club, and has delivered four lectures in the Garden 
lecture courses. 
Dr. Fred J. Seaver, Curator, continued as editor of the 
JournaL of the Garden and also as associate editor of 
Mycotocra. Much time was spent in the naming of fungi 
and in the preparation and mounting of this material. A 
limited amount of time was spent collecting fungi of the 
local flora region. This work resulted in the discovery of 
several undescribed discomycetes and the addition of many 
valuable specimens to our collections. Critical preliminary 
studies have been continued on certain groups of ascomycetes 
for monographs for Nort American Frora. During the 
summer months considerable time was devoted to the study 
of insect parasites in the Garden and on the means of con- 
trolling them. One lecture dealing with this subject was 
given in the regular Garden lecture courses and also before 
the New York Horticultural Society. Dr. Seaver recently 
accompanied you to Bermuda for the collection and study 
of the fungi of that island. He also published several papers 
on different groups of fungi. 
Dr. Arthur Hollick, Curator, was granted leave of 
absence for the first quarter and the last quarter of the year 
in order that he might continue the study of the collections 
of fossil plants made by him in Alaska several years ago under 
the auspices of the United States Geological Survey. From 
the Ist of April to the 31st of October Dr. Hollick cared 
for the collections of fossil plants, and in this connection 
he had the continued voluntary assistance of Mr. Edwin W. 
Humphreys. Dr. Hollick continued his studies on the fossil 
plants of the vicinity of New York City and prepared the 
manuscript and drawings of several papers, one of which, 
“Additions to the Paleobotany of the Cretaceous Forma-
