the early part of the year, from time to time, and was 
completed in July. Several gaps in the biologic series 
were filled by exchange of specimens with the Garden, 
through which the Garden acquired a valuable lot of 
paleobotanical material from the collections made by the 
Peary Expedition in Greenland in 1891-1892. 
Study of the fossil plant remains collected in Porto Rico 
by the joint natural history survey of the New York 
Academy of Sciences and the American Museum of Natural 
History was continued and drawings were made of speci- 
mens to be described. 
Preliminary studies were begun of two interesting col- 
lections of fossil plants from Cuba,—the first recorded 
collections of the kind from that island, as far as I am 
aware—transmitted as a gift to the Garden by Brother 
Léon from Matanzas. 
On November 28 I delivered a lecture before the Buffalo 
Society of Natural Sciences, as a part of their public lecture 
course for 1919-1920, on ‘‘ Plants Concerned in the Forma- 
tion of Coal.” On December 2 I left for Washington to 
resume work in connection with the United States Geological 
Survey on the fossil flora of Alaska, which was interrupted 
during the past two years by the exigencies of the war. 
Respectfully submitted, 
Artuur Ho.tick, 
Honorary Curator of the Collections of Fossil Plants.
