year before our building was completed and the library went into 
its new quarters. Over 6,200 parts of publications were received 
during the year, 1,160 bound volumes, and 702 pamphlets—a total 
of 8,062 pieces. The number of current periodicals now being 
received is 529, and the total number of volumes and pamphlets, 
excluding duplicates, is 13,140. 
Herbarium 
The phanerogamic herbarium has increased by gift, exchange, 
and purchase by 9,088 specimens; 219 specimens have been sent in 
exchange. The gifts are acknowledged in Appendix I (p. 79). 
In my preceding report I noted the fact that the herbarium cases 
were then full to capacity, and that additional cases were needed 
properly to care for the new specimens that are continually coming 
in without active effort on our part. The accessions of 1921 have 
naturally made this need more acute. 
The appended report on the Cryptogamic Herbarium records the 
accession of 330 specimens of fungi by gift, purchase, exchange, 
and collection, and 50 specimens of mosses by purchase. Special 
attention is called to the need of extending this collection, especially 
along the lines of research work in progress at the Garden. 
Conservatories 
The attendance at the conservatories continues to increase, the 
number for 1921 (over 19,000) being nearly 5,500 in excess of 
1920. The necessity of taking House No. 7 for plant-breeding 
cultures has greatly increased the congestion and restricted the 
number of species in the collection. The need for the new range 
of larger conservatories, which is a part of the original plan of the 
Garden, has now become very urgent. 
Plantations and Grounds 
North Addition—During the fall work was begun on the final 
grading of the north addition, lying between the Brooklyn Museum 
building and Mt. Prospect reservoir, and fronting on Eastern 
Parkway. This area, of about three acres, was added to the
