110 REPORT OF NATIONAL MUSEUM, 1914. 
of that island by Mr. E. D. Merrill. Other collections worthy of 
mention were 2,000 specimens from the arid regions of Colorado, New 
Mexico, and Texas, contributed by the Carnegie Institution of Wash- 
ington; 740 specimens from the mountains of North Carolina, ob- 
tained by Mr. Paul C. Standley and Mr. H. C. Bollman; 1,075 plants 
of the Henry Eggert Herbarium, largely from the south-central 
United States, received in exchange from the Missouri Botanical Gar- 
den; and 940 specimens, chiefly from Idaho, from the University of 
Wyoming. 
Approximately 33,000 specimens were mounted for the general her- 
barium, which is much above the yearly average, and at the close 
of the year few remained to be prepared in this way. In other re- 
spects also the work of the division was well advanced and the collec- 
tions were reported in excellent condition. By the employment of 
two extra assistants, an accumulation of about 50,000 mounted speci- 
mens of phanerogams was appropriately distributed in the cases and 
nearly one-half of the phanerogamic collection was rearranged, a 
considerable proportion of the specimens being likewise put in new 
covers. This revision will go on until it has been completed for the 
entire group. 
As opportunity permitted, Mr. Standley continued the segrega- 
tion of types and duplicate types from the study series. This work, 
which may be said to have progressed steadily for more than a 
year, has led to the assembling of upward of 7,000 specimens. Each 
type, after being plainly indicated as such, is placed in an indi- 
vidual cover of heavy manila tag board, with a distinctive label on 
which is written not only the generic and specific name but also the 
serial number of the genus according to the classification of Dalla 
Torre and Harms. The type specimens thus far removed from the 
general herbarium sequence have been associated in eight standard 
cases, placed conveniently near the offices of the assistant curators, 
so as to be easily cared for and still be available for consultation by 
investigators. The probational appointment of Mr. Glen P. Van 
Eseltine as aid has made it possible to carry out a plan long held 
in abeyance to place the cryptogamic collections in better order. 
During the past five or six years a large amount of material has 
accumulated in nearly all groups of the lower cryptogams, and 
although a part of this is in shape for immediate incorporation in 
the reserve series the greater part remains to be attended to, and the 
proper pocketing, labeling, and distribution involves much time and 
labor. The herbarium has been thoroughly poisoned by carbon 
bisulphide twice during the year. Only a few insects have been 
observed, and in no instance has any special damage been caused 
by them.
