“ These tribes were formerly turbulent, and a source of trouble to the Mahommedan governors of Bengal and Behar; but the introduction of British rule has secured peace and security, and the aboriginal races of Chota Nagpur are now peaceful and orderly subjects. The principal agricultural products are rice, Indian corn, pulses, oil-seeds and potatoes. A small quantity of tea is grown in Hazaribagh and Ranchi districts. Lac and tussur silk-cloth are largely manufactured. The climate of Chota Nagpur is dry and healthy. ”
