The spring inspection of grounds, buildings, and collec- 
tions on May 4 was successfully carried out under the 
auspices of the Auxiliary.* Members of the Auxiliary 
visited the Garden on the afternoon of October 26, with 
members of the Corporation, to view construction work in 
progress. 
Administrative 
A vacancy in the Board of Managers was filled in June by 
the election of Mr. Adolph Lewisohn for a term expiring 
in January, 1919. 
Maintenance details have been largely referred to Dr. 
W. A. Murrill, Assistant Director, and to Mr. R. 8. Wil- 
liams, Administrative Assistant, under my immediate 
supervision. I have personally supervised all new con- 
struction, including paths, drainage and grading, and the 
development of new plantations, which has been under the 
immediate direction of Mr. Arthur J. Corbett, Superin- 
tendent of Buildings and Grounds, and of Mr. John Finley, 
Foreman Gardener. The immediate care of the collections 
of living plants and of new planting has been in charge of 
Mr. George V. Nash, Head Gardener, and the care and 
increase of the museum collections has been under the di- 
rection of Dr. John K. Small, Head Curator, and others of 
the curatorial staff. The laboratories and experimental 
grounds have been in charge of Dr. A. B. Stout, Director of 
the Laboratories, and the library has been administered by 
Dr. John H. Barnhart, Bibliographer, and Miss Sarah H. 
Harlow, Librarian. 
I have continued, during times not required adminis- 
tratively, investigation of the cactus family in cooperation 
with Dr. J. N. Rose, of the Carnegie Institution of Wash- 
ington, and two volumes of the Monograph of the Cactaceae 
to be published by that institution are now essentially com- 
pleted; I have also given some time to the continuation of 
my investigations on the flora of the West Indies.
