Assam.—

Mr. Mann reports with respect to the small patches of Cinchona plantations below Nungklow, in the Khasia Hills:—" Cinchona officinalis appears to be healthy, the other two species (Cinchona succirubra and Cinchona micrantha) all present a very sickly appearance, and most of them have only a few leaves at the extremities of the branches. Both species flower sparingly and form no good seedpods. This condition of the plants is ascribed not so much to the climate and altitude as to the very steep slope and shallow surface soil resting on rock, which does not retain sufficient moisture to suit these plants. The plants of Cinchona succirubra, near Jirang, look very much better, and both altitude and situation, as well as the soil in that place, seem to be more suited to this species than in the Nungklow plantations."
