Fully 11,000 duplicate specimens were distributed, as 
exchanges, to several institutions and individuals in this 
country and abroad. 
JJ. ARRANGEMENT OF THE HERBARIUM. The increase 
of the herbarium necessitated considerable rearrangement of 
several plant groups. Forty-one standard cases were added 
to the herbarium equipment ; thirty-one of these were arranged 
in the large room at the extreme western end of the third 
floor, and the fungus collections have been placed in these 
cases. Ten cases were arranged in the main herbarium room 
to accommodate the additions made to the collection of flower- 
ing plants. Three special wall cases were built in the room 
formerly occupied by the collection of fungi to accommodate 
the rapidly increasing collections of mosses and ferns. Valu- 
able sets of specimens from tropical America, both from the 
Antilles and from the mainland were added to the permanent 
collections. 
Assistance and Investigations 
Dr. W. A. Murrill, First Assistant of the Director-in-Chief, 
has had charge of the collection of fungi. Through his 
efforts considerable additions to the fungus collections were 
made, largely through the determination of specimens, and 
he has prepared twenty-five duplicate sets of the commoner 
polypores of the region about New York City. He published 
an article on Philippine polypores in the Bulletin of the Torrey 
Botanical Club. Two parts of the North American Flora, 
including the polypores, were completed and one has been 
published as number one of volume nine of that work.
