plants from the Don River Valley, Ontario, sent by Profes- 
sor J. H. White, of the University of Toronto. In each 
instance duplicate specimens have been secured for the 
Garden collections in return for the work performed. 
About 50 specimens have been accessioned, labeled, and 
arranged in their proper cases, while a number of others are 
awaiting identification and future study. Mr. Humphreys 
is assisting in this work. 
A number of manuscript labels have been replaced by 
printed ones. Copy for all of the former that yet remain 
has been transmitted to the printer and as fast as the 
printed ones are received they will be installed. 
One student has received instruction in paleobotany 
under my direction; and I had the privilege of delivering 
two lectures on paleobotanical subjects in the regular 
Saturday afternoon courses. Every effort was made by 
means of exchange of publications to add to the paleo- 
botanical library, and thirty-two volumes and pamphlets 
were thus secured. 
Respectfully submitted, 
ArtuHur Hotticx, 
Honorary Curator of the Collection of Fossil Plants.
