The Indian army and the Indian strategical railways are therefore organised with special reference to the belt of territory which extends north-east and south-west beyond the Indian desert, and is traversed from end to end by the Indus river. This frontier belt divides naturally into two parts. Inland we have the Punjab, where five rivers—the Indus, Jhelum, Chenāb, Rāvi, and Sutlej—emerging from their mountain valleys, gradually close together through the plain to form the single stream of the Lower Indus; seaward we have Sind, where the Indus divides into distributaries forming a delta.
