livered by him in connection with the Saturday afternoon 
courses and one in the nature-study course given to the 
pupils of grades 4B and 5B of the public schools of the 
Borough of the Bronx. 
Dr. Marshall A. Howe, Curator, continued in charge of 
the collections of algae and hepaticae. The work of incor- 
porating the Mitten and the Underwood collections of 
hepaticae in the general hepatic herbarium has been com- 
pleted, resulting, during the year, in the mounting and dis- 
tributing of 5,722 new herbarium sheets and 1,463 odd pock- 
ets of hepaticae. Of algae, 1,395 new herbarium sheets, 28 
pockets, and 15 boxes have been entered in the herbarium. 
For the sake of preserving the actual materials from which 
figures and descriptions have been drawn and for facilitating 
microscopic comparisons of specimens, about 800 sections 
and other microscopic preparations of algae have been 
mounted in glycerine jelly on slips of mica and have been 
introduced into the herbarium beside the specimens. 
The writer, in addition to regular curatorial work, finished 
monographs of the families Ericaceae and Monotropaceae 
for publication in NortH American Fiora. Some time 
was devoted to the study of specimens collected during 
exploration in tropical Florida in 1912, while studies on 
certain plants and plant-groups of the southeastern United 
States were carried on from time to time. As a side issue, 
I published a second edition of my ‘Flora of the Southeastern 
United States” in the spring, and also five other books which 
succeeded the “Flora” in the following order, “‘Flora of 
Miami,” “Florida Trees,” “‘Flora of the Florida Keys,” 
“Flora of Lancaster County” (in collaboration with J. J. 
Carter), and “Shrubs of Florida.” Extensive exploration 
was carried on in the everglades of Florida, chiefly in parts 
hitherto unexplored, during parts of November and Decem- 
ber, and some time was devoted to exploration and collecting 
on the lower Florida keys. 
Respectfully submitted, 
J. K. Smatt, 
Head Curator of the Museums and Herbarium.
