PREFACE. 
In January, 1905, Captain John Donnell Smith, of Baltimore, 
Maryland, presented his herbarium and botanical library to the 
Smithsonian Institution. The herbarium, consisting of more than 
100,000 mounted specimens, became a part of the National Herba- 
rium. The library contains some 1,600 bound volumes, consisting 
chiefly of works relative to systematic botany, and being especially 
rich in works relating to Mexico and Central America. For the 
present, the library is to remain in Baltimore, but Captain Smith 
has placed his books freely at the disposal of botanists. 
Not only have the books been selected with great care, but they are 
all in conspicuously handsome bindings. It is doubtful if there is 
any public or private botanical library of its size which can equal 
it in value from either the scientific or the artistic point of view. 
A simple but appropriate book plate has been designed and printed 
and placed in each volume. 
An author catalogue of the library is presented herewith, which, it 
is believed, will be of interest and practical value to many botanists. 
The cataloguing has been done by Miss Alice Cary Atwood, cata- 
loguer in the office of the Botanist, Department of Agriculture, 
J. N. Roser, 
Acting Curator.
