Punjab (25,130), "five rivers," a province in the extreme NW. of India, watered by the Indus and its four tributaries, Jhelum, Chenab, Ravee, and Sutlej; its frontiers touch Afghanistan and Cashmir. Mountain ranges traverse the N., W., and S; little rain falls; the plains are dry and hot in summer. There is little timber, cow-dung is common fuel; the soil is barren, but under irrigation there are fertile stretches; wheat, indigo, sugar, cotton, tobacco, opium, and tea are largely grown; cotton, silk, lace, iron, and leather are manufactured; indigo, grain, cotton, and manufactured products are exported in exchange for raw material, dyes, horses, and timber. The population is mixed, Sikhs, Jats, and Rajputs predominate; more than a half are Mohammedan, and more than a third Hindu. Lahore is the capital, but Delhi and Amritsar are larger towns. Several railways run through the province. The natives remained loyal throughout the Mutiny of 1857-58, Sikhs and Pathans joining the British troops before Delhi.
