CHAPTER XI 



FAMILY COMPOSITE 



THIS important family includes the artichoke 

 (globe and Jerusalem), chicory, endive, lettuce, salsi- 

 fy, and sunflower. As far as we know, there are no 

 available statistics of the acreage and money value in 

 the United States of artichoke, chicory, salsify, and 

 sunflower. They are, nevertheless, of considerable 

 economic importance. According to the Thirteenth 

 Census of the United States (1909) the area in lettuce 

 was 5489 acres, and the crop is estimated at $1,595- 

 085. Florida leads with 1450 acres and New York 

 follows with 1012 acres. The other States in order 

 of importance are California, Louisiana, Massachu- 

 setts, Illinois, New Jersey, Missouri, Pennsylvania, 

 Ohio, Virginia, and Maryland. States with less than 

 100 acres of lettuce are omitted. 



DISEASES OF ARTICHOKE, JERUSALEM 

 (Helianthus tuberosus) 



Jerusalem artichoke is subject to the attack of but 

 few diseases. With the exception of downy mildew, 

 none needs to be feared by the trucker or gardener.
