Besides this work of our regular students, many visiting 
botanists have pursued their researches in our herbarium 
andlibrary. Especially noteworthy is a visit by Dr. William 
Trelease, for the study of the genus Phoradendron. 
In addition to this very general use of the herbarium by 
visitors, a great amount of service has been rendered in the 
naming of specimens sent in to us for that purpose. In 
the division of Fungi, the amount of such work has nearly 
doubled over that of the preceding year. 
Some extensive and valuable exchanges of specimens have 
been arranged during this year. 
Continued progress has been made in the control of the 
Hickory and Hemlock beetles, as well as of the Cactus fly. 
Our relations with the work of other institutions have been 
cultivated and extended. In association with the New 
York Horticultural Society, the usual meetings and plant 
exhibitions have been held. ‘The newly organized New York 
State Forestry Association has held a convention at the 
Garden and has been entertained by us. Delegates from or 
representatives of the Garden have attended the meetings 
of the New York Library Club, the American Association for 
the Advancement of Science, the National Park Superin- 
tendents’ Convention, and the inauguration of Dr. Finley 
as State Commissioner of Education and President of the 
University of the State of New York. Close association 
has obtained with the Torrey Botanical Club and the 
Brooklyn Botanic Garden. Our relations with the herba- 
rium of the National Museum have been peculiarly close, 
and mutually helpful, especially in connection with the 
study of Cactaceae, which work continues to be vigorously 
pursued by Dr. Britton and Dr. Rose. 
Our public lecture courses have included thirty-five 
lectures, in addition to the spring course to the pupils of 
the public schools. Our fall course represented a new de- 
parture in our lecture division, in that it took up the various 
phases of a single subject, that of vegetable foods, presented 
in the form of a symposium. The result of this experiment
