FIFTEENTH ANNUAL REPORT OF THE DIRECTOR. 29 
Though fewer cards have been written at the Garden 
than usual, the card index was enlarged in 1903 by the 
incorporation of 8,263 cards, of which 1,872 were written 
by employees, 1,067 were presented, and 5,324 were pur- 
chased, the expenditure for cards and cases amounting to 
$46.07. The total is now 311,218, an increase of 66,533 
over the number at the endof 1898. ‘his increase, shown 
on the accompanying diagram, amounts to 27.7 per cent of 
the number recorded at the end of 1898,* or about 5.5 per 
cent for each of the last five years.

INDEX CARDS. 
The Secretary’s statement shows that in 1903, $3,026 70 
was spent for library purchases and binding, —in the 
latter of which directions unusual progress has been made 
this year though many of the large sets of serials, which 
have come to us unbound, are still in this condition. 
As with the herbarium, the library has so far outgrown its 
quarters in the administration building as to necessitate 
the removal of many books to the old museum, but the 
subject classification adopted on the shelves renders these 
scarcely less accessible than the others, and they are as 
safely housed.
