Varieties. There has been no satisfactory study of the varieties of cane, and, in consequence, there is no satisfactory system of classification of the varie- ties. The division most usually spoken of by plant- ers, and that which may therefore be inferred to be the one they find est and best plowing is accomplished with steam plows, the depth reached within economic limits being eighteen inches to two feet. Sometimes sub- soil tools are alleged to go below two feet, but that is rare. The limitations are often determined by the nature of the subsoil, which in some localities is such that it is inadvisable to turn it up to the surface except in small quantities. In some volcanic soils, for example, the iron compounds in the sub- soil are injurious to the growth of cane. Good surface tillage after plowing pays as well with cane as with any other crop. All the labor- saving implements connected with big-scale agri- culture are in use in some regions. most useful, is based on the color of the stalk. Three color- groups are recognized: (1) the green and yel- low group, in which the stalk is more or less uniformly green or yellow; (2) the red group, in which the stalk is more or less uniformly reddish in color; and (3) the striped group, in which the stalk is more or less distinctly striped. This grouping is wholly, or almost wholly arbitrary, and presents little to rec- ommend it from a
