REPORT OF THE OFFICERS OF THE BOARD. 23 
library and herbarium — averaging $1,775.36 per year for 
the past 13 years— are received in exchange from cor- 
respondents to whom the Reports are sent. 
EXCHANGES. 
Though already planted and partly equipped, the Garden 
was without scientific affiliations when its development was 
entrusted to the Board. To bring it into exchange relations 
with other establishments, the publication of these annual 
volumes, devoted to administrative reports, scientific mono- 
graphs, etc., was early decided on. Through the medium 
of this publication the Garden now stands in exchange re- 
lations with 859 institutions interested wholly or in part in 
botany, gardening, horticulture or forestry. The exchange 
of plants and seeds with other gardens has recently been 
- greatly increased by the issuance of an annual exchange 
seed list which is sent to the officers of such establish- 
ments, who may thus readily ascertain and request such of 
their desiderata as can be furnished. The first seed list 
included 813 species, and the list just issued contains the 
names of nearly 1,400 kinds of plants of which seeds were 
saved for exchange purposes in 1905. 
POLICY OF ADMINISTRATION. 
Through its entire history under the management of the 
Board the Garden has been treated as a public institution 
inthe fullest and most liberal meaning of the term. None 
of its Trustees receive any form of remuneration for their 
services. It is not managed as a source of revenue. Such 
of its publications as are sold are charged for at cost. Its 
employees, who are always required and ready to render 
any proper service in their power, are forbidden to accept 
fees. The office staff devote a large part of their time to 
examining into and reporting on questions put in connec- 
tion with a large correspondence or asked by visitors.
