At present, 1,133 serial publications are received at the 
library. Of these, 101 are purchased, and 1,032, issued by 
765 institutions or publishers, are presented or received in 
exchange for the Reports of the Garden. 
Of the small handbook of the Garden, issued in 1893,

erected for the important research work on the causes of 
the decay of timber, etc., being conducted by Dr. von 
Schrenk of the School of Botany, in connection with the 
United States Department of Agriculture.

7th, of Miss Eva M. Reed, who for some eight years had 
occupied the position of indexer in the library. From the

position of botanical assistant for about five years, left the 
Garden to become Professor of Botany and Vegetable 
Pathologist at the Maryland Agricultural College, and the 
vacancy resulting was filled by the appointment of Mr. J. 
Arthur Harris, a graduate of the University of Kansas. 
Approximately the same amount of time as in preceding 
years has been given by the herbarium and office staff to
