CULTURAL DIRECTIONS 227 



Various methods of classification have been suggested. 

 Corbett (Farmers' Bulletin 289, pp. 7-8) has proposed 

 the following arrangement, which is satisfactory for all 

 practical purposes : "For convenience in reference and 

 for discussion, beans may be divided into two gen- 

 eral groups — 'field' and 'garden' beans — which are by no 

 means distinctly separate either in appearance or in char- 

 acteristics. Each of these groups can again be divided 

 into bush and pole beans. Bush beans of the field type 

 are recognized, for commercial purposes, under three 

 well-marked types, known as kidney, marrow and pea 

 beans, each of which may be subdivided into two groups, 

 colored and white. The garden beans, like the field 

 beans, may be divided into bush and pole types ; these 

 again into kidneys and limas, the term 'kidney' in this 

 case including all of the common garden beans whether 

 of one type or another, and this group may again be 

 divided into wax and green pod. The same subdivision 

 may also be provided under pole beans, as is suggested 

 in the following classification :"
