New Brunswick. More than 600 species and varieties of flowering plants 
and ferns were collected. 
H. M. Raup, assisted by Mrs. Raup, continued investigations on the 
flora of Wood Buffalo park, Alberta. 
J. Rousseau made a botanical exploration of the districts of St. Urbain 
and Matapeclia, Quebec, collecting about 500 flowering plants and ferns, 
aggregating approximately 3,000 herbarium sheets. 
M. O. Malte continued work on Arctic botany in co-operation with 
Professor C. H. Ostenfeld, Copenhagen, Denmark, who spent about one 
month at the National Museum determining collections and preparing 
manuscript for a “Flora of Arctic Canada.” 
Through the co-operation of the Forestry Branch, Department of the

DIVISION OF MINERALOGY (Geological Survey) 
Eugene Poitevin, Chief of the Division, reports: 
Field Work and Laboratory Work 
(See also under Geological Survey in Annual Report of the Depart- 
ment of Mines.) 
Keeping pace with the general progress of recent years the Division 
of Mineralogy during the year just ended has collected, exchanged, and 
placed on exhibit a large number of mineral specimens. It has also con- 
tributed to the knowledge of mineralogy by the scientific investigation of 
many mineral species. 
More than three thousand rock and mineral specimens were examined 
and studied and 50 per cent of these were added to the systematic and 
economic collections. 
Several table cases were filled with exhibits, thus adding to the large 
number of cases already on display in the Museum. 
In addition to the identification of a large number of minerals in- 
tended to be placed in the systematic collection, the mineralogists of the 
division have carried out the following research w r ork: 
Eugene Poitevin and R. J. C. Fabry have completed their study of 
the lithium minerals from the pegmatites of the Silver Leaf property in 
southern Manitoba.
