"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 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.
The district naturally divides itself into three well-defined tracts - (1) The salt tract, along the coast; (2) The arable tract, or rice country; and (3) The submontane tract, or jungle lands.
The submontane tract is an undulating country with a red soil, much broken up into ravines along the foot of the hills.
The submontane valleys are largely cultivated, but are deadly except to those born in them.
