of that island by Mr. E. D. Merrill. Other collections worthy oi 

 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 910 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 Avere 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 nmnber 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 gi'oups 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.
