20 MISSOURI BOTANICAL GARDEN. 
In the summer of 1898, Dr. George J. Engelmann, who, 
for six years, until his removal from St. Louis, served asa 
member of the Board of Trustees of the Garden and who 
is still a member of the Advisory Committee of the School. 
of Botany, and to whom the Garden is indebted for the pre- 
sentation of the invaluable herbarium, library and manu- 
script notes of his father, the late Dr. George Engelmann, 
added to these gifts a large series of letters received at vari- 
ous times by his father from the leading botanists of the 
world. These, as well as a number of letters written by 
Dr. Engelmann which have come into the possession of the 
Garden in the same manner, are being preserved, and will 
ultimately be suitably mounted in bound volumes, to be 
added to the series of volumes of manuscript notes and 
sketches by Dr. Engelmann, to which reference has been 
made in earlier reports.* 
As many additions have been made to the Sturtevant 
Library since the catalogue of this collection was pub- 
lished,f a supplementary catalogue of works published 
before 1753 has been prepared by Mr. C. E. Hutchings, 
for publication, if practicable, in the Tenth Report of the 
Garden. 
So much of the result of Dr. Sturtevant’s work on the 
literature of cultivated plants is now, by his own provision 
and action, preserved at the Garden, that, on my recom- 
mendation, the Board of Trustees have secured, through 
the kindness of Professor C. S. Plumb, of Indiana, who 
knew him well, the preparation for the Tenth Annual 
Report of a biographical sketch of Dr. Sturtevant, accom- 
panied by an enumeration of his principal publications. t 
Though the actual equipment of a research institution 
speaks for itself, it is unusually gratifying to the Director 
and Trustees of the Missouri Botanical Garden to receive, 
in gifts like those from Dr. Sturtevant,§ the most direct
