Kafiristan ("Land of Unbelievers"), a little-known region on the N.W. frontier of India, inhabited by an Aryan race (Siahposh), who speak a language akin to Sanskrit, and worship one Supreme Being (Imbra). The country, which is bounded on the W. and S. by Afghanistan, is intersected by numerous ridges, from 11,000 to 17,000 feet in height, mostly running from the Hindu Kush range on the N.W. The various tribes occupying the valleys between these are not apparently bound together by any political tie. The best authenticated accounts represent the Siahposh Kafirs as bold, robust, undersized, jovial, and fond of amusement.
