Editorial and Research Work 
Owing to paper shortage and general adverse conditions only 
eight numbers of the Leaflets were issued during the year, against 
the usual fourteen numbers; two of these were , however, of 
double size. With one or two exceptions, these were written on 
subjects having to do more or less directly with war-gardens. 
The American Journal of Botany, also published by the Garden 
in cooperation with the Botanical Society of America, has, with 
the ending of 1918, completed its fifth year, fulfilling an impor- 
tant function in the botanical world. 
As reported in the Recorp for October, 1918, I spent my sum- 
mer vacation in plant disease work in New York, Virginia and 
Pennsylvania for the Plant Disease Survey and Cereal Disease 
offices of the United States Department of Agriculture, cooper- 
ating with the Departments of Plant Pathology at Cornell and 
at the Virginia Polytechnic Institute, and with the Pennsylvania 
State Department of Agriculture. In addition to the work there 
recorded, I assisted in the work on the new and serious disease 
of Potato Wart, recently discovered in the gardens of many of 
the anthracite coal miners around Hazleton, Pennsylvania. 
Respectfully submitted, 
Epcar W. OLIvE, 
Curator of Public Instruction.
