barium, 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 specimens from less 
accessible regions. It is especially rich in material illustra- 
tive 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, including veneer transparencies and slides for the micro- 
scope. The library, containing about 8,000 volumes and 10,000 
pamphlets, includes most of the standard periodicals and proceed- 
ings of learned bodies, a good collection of morphological and 
physiological works, nearly 500 carefully selected botanical vol- 
umes published before the period of Linnaeus, an unusually large 
number of monographs of groups of cryptogams and flowering 
plants, and the entire manuscript notes and sketches representing 
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 Engelmann, 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 like- 
wise afford unusual opportunity for morphological, anatomical and 
physiological studies, while the planthouse facilities for experi- 
mental work are steadily increasing. The E. Lewis Sturtevant 
Prelinnean library, in connection with the opportunity afforded 
for the cultivation of vegetables and other useful plants, is favor- 
able also for the study of cultivated plants and the modifications 
they have undergone. 
These facilities are freely placed at the disposal of professors 
of botany and other persons competent to carry on research work.
