KOHAT PASS  , a mountain pass in the North-West Frontier Province of India, connecting Kohat with Peshawar . Fromthe north side the defile commences at 41 m . S.W. of Fort Mackeson, whence it is about 12 or 13 M. to the Kohat entrance . The pass varies from 400 yds. to I4 m. in width, and its summit is some 60o to 700 ft. above the plain . It is inhabited by the Adam Khel Afridis, and nearly all British relations with that tribe have been concerned with this pass, which is the only connexion between two British districts without crossing and recrossing the Indus (see AFRini) . It is now traversed by a cart-road .
