Public Instruction and Information 
Instruction by public lectures and demonstrations and 
by docentry has been continued, all members of the staff 
participating. Following the suggestion in my last annual 
report, the position of Supervisor of Public Instruction 
was established in January, 1919, and Dr. William A. 
Murrill, formerly my First Assistant, was appointed to 
fill it. Under his direction, educational work, especially 
in docentry, has been expanded, and he has delivered 
lectures on various topics at the Garden and elsewhere. 
He was placed in charge of a very successful exhibition 
of plants used in decorative design held at the Metropolitan 
Museum of Art in March and April, in cooperation with 
that institution. The completion of the central display 
greenhouse, given by Messrs. Daniel and Murry Guggen- 
heim, including space for public lectures and exhibitions, 
provided important additional facilities for lectures de- 
livered there on Saturday afternoons in November, to be 
continued. At the November meeting of the Board of 
Managers, a series of Sunday afternoon lectures, in addition 
to the Saturday courses, was authorized, and these will be 
commenced in the spring. Dr. Murrill’s report hereto 
appended gives details of the public educational work. 
Replies to all requests for botanical information have 
been continued and all questions, oral or written, have 
been replied to; these questions have been numerous and 
the correspondence of the institution continues very large.
