Sihca and iron in the drysubstance of the leaves decreased irregularly from Plats I to IV, whilethe magnesia decreased regularly. In the dry substance of the rootsthere was an appreciable increase in lime in Plat II only; magnesiaand iron decreased regularly from Plats I to IV. The amount of ashin the leaves increased shghtly from Plats I to IV. The compositionof the ash in leaves and roots showed about the same variations asthe ash constituents in the dry substance. Taking the plant as a whole Geaves and roots together), it appearsthat the plants grown on the plats with CaCOg differed from the checkplants in containing about 12 per cent more lime, 7 to 17 per cent lessmagnesia, and 15 to 35 per cent less FiQ. 1.—Sweet Cassava Grown with i-: i
