SUGAR-CANE SUGAR-CANE 601 of differing degrees of earliness, by varying the planting season, by taking advantage of low land and high land and other natural conditions, it is possible to extend the crushing season so as to get a maximum result from the capital invested in the mill and from the laboring force of the plantation. As we shall see later (page 602), the time of ripen- ing, i. e., the distribution of the sugar in time, as well as the distribution of the sugar in the stalk, have much to do with the selection and preparation of seed-cane. The kind of sugar present in the cane, as well as the amount of it, determines its industrial value. The propei'ty that makes the saccharine substance of the greatest industrial value at the present time, is that of its being extractable loy the known processes of crushing, concentra- tion and crystallization. Preeminent among the extractable saccharine substances of this nature is sucrose. This crystallises out as "cane-sugar," and is the same substance as that obtained from sugar-beets and a variety of other plants. In fact, from a practical point of view, at the present time, we may say that the amount of extractable .sucrose determines the value of the cane more than any other factor except that of ability of the cane economically to reproduce itself with this sugar- content unimpaired. We must not forget in this connection, however, that the ease with which the sugar can be extracted is also an important factor. The presence of saccharine matters other than sucrose is deprecated by planters because their pres- ence generally indicates a lowering of the sucrose, the energy of the plant having been consumed in producing sugar or saccharine matter that is not extractable, in place of a certain amount of sucrose that might have been produced. The extractability of the sucrose depends to a certain extent on the absence of certain organic substances which tend
