Do'ab

Do'ab (from the Sanskrit, 'two rivers;' cf. Punjab) is a term used in India for the country between any two rivers, but specially the space enclosed by the Jumna on the south-west and the Ganges on the north-east—a space extending from Allahabad to the base of the Himalayas, a distance of upwards of 500 miles, with an average breadth of 55 miles. It is the granary of upper India, its great natural fertility having been increased by the Ganges, Lower Ganges, and Eastern Jumna canals, and the extensive irrigation system which these render possible. It is all well cultivated, and is densely peopled throughout.
