*Nāgā hills*.—The Nāgā hills form part of the eastern frontiers of Assam. The district of the Nāgā hills is bounded on the north by Śibsāgar; on the west by Śibsāgar, Nowgong, and the North Cachar hills; on the south by Manipur, and on the east by mountain ranges inhabited by independent Nāgā tribes. The district consists of a narrow strip of hilly country and has a maximum length of 138 miles and an average breadth of about 25 miles. The hills are covered with dense evergreen forests. North of Kohima the main range gradually declines in height. The Nāgā hills are generally composed of pretertiary rocks overlain by tertiary strata. The most important coal-fields in the Nāgā hills lie outside the borders of the district.
