indicated in each of the previous reports.* During 1898, 
260 books and 76 pamphlets were purchased, the total 
expenditure for the library, as shown by the Secretary’s 
books, being $1,731.76 ; and 427 books and 867 pamphlets, 
appraised at $1,103.60, were presented or received in

The manuscript index has been increased by the addi- 
tion of some 62,248 cards. Of these an estimated number 
of 52,300, referring to the literature of field, garden and 
orchard plants, were presented to the Garden by the late 
Dr. E. Lewis Sturtevant, who personally attended to care- 
fully packing them for shipment, shortly before his death, 
in July last ; 4,365 cards, chiefly referring to the literature 
of the agricultural experiment stations and to new species 
and varieties of plants described within the last few years, 
were bought, and 5,583, largely referring to illustrations, 
were written by employees of the Garden.
