and carrot. Denmark supplied beets and other root-crops 

 as well as the cabbage-like vegetables. France sent to us 

 radish, carrot and seeds of annual flowers. Japan supplied 

 seeds of rape and similar plants. What effect the War will 

 have on the permanent sources of seed supply cannot yet be 

 stated. 



The accompanying maps, Figs. 1 and 2, show the special 

 sections in the United States for the production of field seeds 

 and vegetable seeds respectively, as reported by R. A. Oakley 

 in an interesting article on "The Seed Supply of the Nation" 

 in the Yearbook of the Department of Agriculture for 1917. 



The figures of seed-production given on page 5 will undoubt- 

 edly be greatly increased by the forthcoming census. Ap- 

 parently the United States requires upward of 110,000,000 

 pounds of red clover seed, for example ; at present farm prices 

 (1919), the value of it would be about $66,000,000. 



Persons interested in the seed-production of the United 

 States should be in touch with the Seed Reporting Service, 

 Bureau of Markets, U. S. Department of Agriculture, and 

 should consult the Seed Reporter, a monthly publication. 



Not only in seeds but in bulbs and living plants have the 

 North Americans benefited by the skill in plant propa- 

 gation of the Europeans. Many prized international relations 

 have grown up with this importation; a good literature and 

 personal association have developed. What is to be the 

 future of this fraternalism is a source of anxiety to many 

 thoughtful persons.
