pleasure, and information concerning decorative plants and their best 
use, and to provide for beginners the means of obtaining good training 
in botany and horticulture, but also to provide facilities for advanced 
research in botany and cognate sciences. For this purpose, additions 
are being made constantly to the number of species cultivated in the 
grounds and plant houses, and to the library and herbarium, and, as 
rapidly as it can be utilized, it is proposed to secure apparatus for work 
in vegetable physiology, ete., the policy being to secure a good general 
equipment in all lines of pure and applied botany, and to make this 
equipment as complete as possible for any special subject on which 
original work is undertaken by competent students. 
A very large number of species, both native and exotic, and of 
horticulturists’ varieties, are cultivated in the Garden and Arboretum 
and the adjoining park, and the native flora, easily accessible from 
St. Louis, is large and varied. The herbarium, which includes nearly 
250,000 specimens, is fairly representative of the vegetable life of 
Europe and the United States, and also contains a great many speci- 
mens from less accessible regions. It is especially rich in material 
illustrative of Cuscuta, Quercus, Coniferae, Vitis, Juncus, Agave, 
Yucca, Sagittaria, Epilobium, Rumex, Rhamnaceae, and other groups 
monographed by the late Dr. Engelmann or by attachés of the Garden. 
The herbarium is supplemented by a large collection of woods, includ- 
ing veneer transparencies and slides for the microscope. The library, 
containing about 8,000 volumes and 10,000 pamphlets, includes most of 
the standard periodicals and proceedings of learned bodies, a good collec- 
tion of morphological and physiological works, nearly 500 carefully 
selected botanical volumes published before the period of Linnaeus, an 
unusually large number of monographs of groups of eryptogams and 
flowering plants, and the entire manuscript notes and sketches repre- 
senting the painstaking work of Engelmann. 
The great variety of living plants represented in the Garden, and 
the large herbarium, including the collections of Bernhardi and Engel- 
mann, render the Garden facilities exceptionally good for research in 
systematic botany, in which direction the library also is especially 
strong. The living collections and library likewise afford unusual 
opportunity for morphological, anatomical and physiological studies, 
while the plant house facilities for experimental work are steadily in- 
creasing. The E. Lewis Sturtevant Prelinnean library, in connection 
with the opportunity afforded for the cultivation of vegetables and 
other useful plants, is favorable also for the study of cultivated plants 
and the modifications they have undergone.
