From the above observations the following conclusions may be safely deduced, at least so far as our soil and climate bear upon the growth and development of these two varieties of canes, as sugar producing plants: 1. That both varieties are rich in cane sugar. 2. That the Early Amber is richest in cane and the Orange in grape sugar. As grape sugar hinders cane sugar from crystallizing, when in solution with it, in proportion to its amount, it follows: 3. That the sugar in the Early Amber sirup will crystallize more readily, other conditions being the same, than in the Orange sirup. 4. That the Orange yields the greater amount of juice per acre, and if all the sugar in both varieties could be crystallized, the greater amount of sugar. 5. The safest way to secure the full benefit of either the Early Amber or Orange crop for sugar manufacture is to begin cutting the canes when the seed is in the "dough," and to grind them as soon as possible after cutting. 6. The cane sugar of the plants changes into grape sugar after they are once cut off, slowly when under shelter, and rapidly when exposed to the sun's rays.

PROXIMATE ANALYSIS OF SOKGHUM CANE.

An average portion of the Orange cut at the same time—October 6 _ a s that used in experiment 13 was reserved, with tops and leaves still remaining, for the analysis. The leaves and two feet of tops were removed, and cross sections taken between each joint of the remainder of the stalks. The proximate principles were then determined according to the following scheme: The sections, as soon as cut, were weighed and then dried in a water oven, allowed to cool in the air, weighed, finally pulverized, and put in a stoppered bottle. . Of the dried substance, ten grams were required for sugar, fiber, starch, gum and vegetable acids; one gram dov hygroscopic water and a s h ; one gram for total albuminoids; five grams for oil.
