STATES RELATIONS SERVICE. 465 



The <i:rowin<^ of vegetables and fruits is badly neglected in the 

 Virgin Islands, and the station has begun experiments on the adapta- 

 bility of weli-knoAvn varieties of common tropical and temperate 

 climate fruits and vegetables. Tomatoes, string beans, carrots, kold- 

 rabi, beets, etc., were all grown very successfully during the past 

 year. Cabbage, melons, cucumbers, and others grew well, but were 

 badly injured by insect attacks. P'xperiments are in progress for 

 the contiol of these pests. An effort is being made to introduce the 

 papaya into general use as a fruit and vegetable, and a large amount 

 of seed was distributed throughout the island. Plantings of man- 

 goes, avocados, and citrus trees were made at the station, and some 

 of the lime trees in the small orchard planted in 1915 have been 

 successfully top-worked to grapefruit. On account of the limited 

 supplies oi fruits and vegetables in vaiietj'^, especial efforts will be 

 made not only in St. Croix but in the other islands to stimulate their 

 production. 



OFFICE OF EXTENSION WORK IN THE SOUTH. 



J. A. Evans, Chief. 



The Office of Extension Work in the South has charge of the co- 

 operative extension work of the Department of Agriculture in the 

 15 Southern States. Except the decrease in administrative organiza- 

 tion, noted below, its functions, administrative organization, and 

 relationships with the subject-matter bureaus of the department and 

 with the State extension services remained unchanged. 



ADMINISTRATIVE FORCE. 



January 15, 1920, Dr. Bradford Knapp, who had been chief of 

 the Office of Extension Work South from the time of its organiza- 

 tion in 1915, retired from the service of the department to become 

 dean of the College of Agriculture of the University of xVrkansas 

 and director of the Arkansas Experiment Station. Dr. Knai.>p had 

 been associated i\'ith his father. Dr. Seaman A. Knapp, in the early 

 development of the farmers' cooperative demonstration work in the 

 Southern States, and succeeded him in the administration of that 

 work while it was connected with the Bureau of Plant Industry. 

 The l)road knowledge of soutliern agriculture possessed by Dr. 

 Bradford Knapp, and his leadersliip in the movement for the im- 

 provement of southern agriculture through the cooperation of farm- 

 ei's, business men, and extension agents, made his services very val- 

 uable and his withdrawal from our service was greatly regretted. 

 His successor is Mr. J. A. Evans, formerly assistant chief of the 

 southern extension office, who has been connected with the demon- 

 stration work since February 12. 1904. 



Within the Department of Agriculture the Office of Extension 

 Work in the South w^as represented at the close of the year by one 

 chief, one assistant chief, three field agents in the administration of 

 the county agent and cooperative extension work in the States; 

 four men and four women in the administration of the home-demon- 

 stration work and the boys' and girls' club work; and the necessary 

 office assistants and clerical force. There was a decrease of two in
