"moist land"), the name of the submontane strip of marshy jungle stretching beneath the lower ranges of the Himalaya in northern India.
It still exists in places along the tarsi or submontane fringe of the Himalayas.
This tract presents the same general features as the Gangetic valley, varied by the damp and pestilential submontane region of the tarai on the north-east, at the foot of the Kumaon hills.
The transGogra region presents a wilder, submontane appearance.
Along the northern border of Gonda and Bahraich districts the boundary extends close up to the lower slopes of the Himalayas, embracing the damp and unhealthy submontane region known as the tarai.
They are succeeded by a broad submontane belt, the tarai, which is rendered moist by the mountain torrents, and is covered by forest from end to end.
The pulses mung, urd and moth are grown generally in the autumn alone, or in combination with millets; and gram, alone or in combination with wheat and barley, is an important spring crop. Sugar-cane, indigo, poppy and tobacco are locally important; and a little tea is grown in the submontane districts of Almora Garhwal and Dehra Dun.
The heights of peaks determined by exact processes of trigonometrical observation are bound to be more or less in error for three reasons: (1) the extraordinary geoidal deformation of the level surface at the observing stations in submontane regions; (2) ignorance of the laws of refraction when rays traverse rarefied air in snow-covered regions; (3) ignorance of the variations in the actual height of peaks due to the increase, or decrease, of snow.
