been destroyed by disease. For the sanie reason, for every two 

 sweet potatoes we bvty we pay for a third, and for every tomato 

 we pay twice what we should. Much of this loss could be re- 

 duced or eliminated by a better understanding of plant diseases. 

 The ultimate economic result of this work in our laboratories 

 should be the supply of a uniformly better quality of food, and at 

 a material reduction in cost to consumers in Greater New York.

Botanical Society of America (1914), Memoirs, irregular (1918). 

 Ecology, quarterly, in cooperation with the Ecological Society of 

 America (1920). The above publications comprise, to date, over 

 4,600 pages of scientific contributions. 



A glance at the map (Fig. 2) will show that the publications 



of the, Brooklyn Botanic Garden go to practically every country 

 and to all the more important intellectual centers in the civilized 

 w^orld. Moreover, the lines on the map not only radiate from 

 Brooklyn; they also converge thither, indicating that publications 



w 



from this wide geographical range are received in our library, 

 where they may be consulted free daily by all who wish.

(c) International Seed Exchange. — Since many years it has 

 been customary for the botanic gardens of the Old World to 

 issue lists of seeds offered in exchange to other similar institu- 

 tions. In 1914 the Brooklyn Botanic Garden printed and dis-

tributed its first List of Seeds, As a result of the exchange rela- 

 tions thereby established, we have received from other botanic 

 gardens over 3,000 packets of seeds from which our collections 

 of living plants have been enriched, and, in return, we have dis- 

 tributed over 8,000 packets. This work was organized by our 

 horticulturist and head gardener, Mr. Free.
