Leaflets 
In Series II of the Leaflets, fourteen numbers were issued, dur- 
ing April, May, June, September, and October, nine of which were 
four-page bulletins, one of eight, while the other four were illus- 
trated and made each up of twelve pages, making a‘total of 80 
pages, with 22 illustrations. The rapid exhaustion of most of the 
editions, and the increasing demand made by teachers for extra 
copies for use with their classes furnish ample evidence of the 
appreciation of the Leaflets by teachers and others, as well as of 
the rapidly growing audience reached by the Garden. One num- 
ber, for example, on the children’s Garden Exhibit, went to over 
10,000 school children; while it was found necessary from time 
to time to increase the number of copies of Leaflets printed.

Investigations 
The research work done by the curator of the department dur- 
ing the year has necessarily been curtailed by growing adminis- 
trative, editorial, and teaching duties; but as heretofore it has 
had to do largely with various plant diseases. In connection with 
this work, the curator joined a party of scientific men on a study
