1911 Encyclopædia Britannica (1911)
“ With the exception of a belt of government forest along the northern frontier, the rest of the province consists of a fertile and densely peopled plain. The greatest elevation (600 ft.) is attained in the jungle-clad plateau of Khairagarh in Kheri district, while the extreme south-east frontier is only 230 ft. above sea-level. Four great rivers traverse or skirt the plain of Oudh in converging courses -the Ganges, the Gumti, the Gogra and the Rapti. Numerous smaller channels seam the whole face of the country carrying off the surplus drainage in the rains, but dryin up in the hot season. ”
