AUTHORITIES.--Information about the Hindu Kush and Chitral is now comparatively exact. The Russo-Afghan Boundary Commission of 1884 and the Chitral expedition of 1895 opened up a vast area for geographical investigation, and the information collected is to be found in the reports and gazetteers of the Indian government. The following are the chief recent authorities:--Report of the Russo-Afghan Boundary Commission (1886); Report of Lockhart's Mission (1886); Report of Asmar Boundary Commission (1895); Report of Pamir Boundary Commission (1896); J. Biddulph, _Tribes of the Hindu Kush_ (Calcutta, 1880); W. M'Nair, "Visit to Kafiristan," vol. vi. _R.G.S. Proc._, 1884; F. Younghusband, "Journeys on the Pamirs, &c.," vol. xiv. _R.G.S. Proc._, 1892; Colonel Durand, _Making a Frontier_ (London, 1899); Sir G. Robertson, _Chitral_ (London, 1899). (T. H. H.*) HINDUR, or NALAGARH, one of the Simla hill states, under the government of the Punjab, India. Pop. (1901) 52,551; area, 256 sq. m.; estimated revenue, L8600. The country was overrun by the Gurkhas for some years before 1815, when they were driven out by the British, and the raja was confirmed in possession of the territory. The principal products are grain and opium. HINGANGHAT, a town of British India in Wardha district, Central Provinces, 21 m. S.W. of Wardha town. Pop (1901) 12,662. It is a main seat of the cotton trade, the cotton here produced in the rich Wardha valley having given its name to one of the best indigenous staples of India. The principal native traders are Marwaris, many of whom have large transactions and export on their own account; but the greater number act as middle-men. There are two cotton-mills and several ginning and pressing factories. HINGE (in Mid. Eng. _henge_ or _heeng_, from _hengen_, to hang), a movable joint, particularly that by which a door or window "hangs" from its side-post, or by which a lid or cover is attached to that which it closes; also any device which allows two parts to be joined together and move upon each other (see JOINERY). Figuratively the word is used of that on which something depends, a cardinal or turning point, a crisis.
