Cane sugar; a textbook on the agriculture of the sugar cane, the manufacture of cane sugar, and the analysis of sugar-house products . in much smaller quantity than asparagine. The Ash of the Cane.—As with the other constituents, distinction mustbe made between the ash of the stalks and that of the leaves, roots, analyses of Hawaiian cane already referred to gave 3-2 per ash in the stalks and 9-5 per cent, in the leaves, etc., both calculated ondry matter; and Popp^^ in some \ery early work found 4*05 per cent, ashin the stalks and 8*25 per cent, in the leaves. The earliest analyses on record are those due to Stenhouse,^* and sincethen very many have been made. Some analyses are vitiated since it isnot stated to what basis the analysis refers, stalks, leaves or whole plant,A selection from the very large number on record is given below and coveringthe extreme variations in composition. This variation will be controlledby variety, the composition of the soU, and by the manures used. The onlyfeatures of constancy are the preponderance of silica in the ash of the leavesand of potash in the Plate ROSE BAMBOO.
