 Nancy Hall, Porto Rico, Big and Little Stem Jersey, 

 Southern Queen or Hayman, and Tolman variety of Old

 standpoint. If grown at all, the less known kinds 

 should be used at home or sold on local markets. Noth-

 Cooperative associations can do' much toward standard-

 select one good variety and grow that exclusively. A 

 dealer who offers only one variety of plants for sale will 

 attract the attention of many who would not otherwise

 through the agencies of cooperative associations or state

 essee, the Nancy Hall. In New Jersey, Delaware, 

 Maryland and Virginia, the Jersey varieties predom-

 in deciding what variety to grow. The market demands

 ern markets at present give preference to the Jersey 

 type, or mealy kinds, though certain varieties grown in 

 lie South are now gaining very rapidly in popularity 

 in the northern, eastern and western cities where here- 

 tofore they were hardly known. As an example of this 

 growth in 1915, The Gleason Sweet Potato Association 

 of Tennessee shipped a carload of Nancy Hall sweet 

 potatoes to a commission house in Chicago. The com-
