Náf (or Anauk-ugay). — An arm of the Bay of Bengal; also a township in Akyab District.--- Şee NAAF. Nágá Hills.— British District forming the south-easterly corner of the Province of Assam. It lies between 25° 13' and 26° 32' N. lat., and between 93° 7' and 94° 13' E. long., being a mountainous border land between the settled District of Nowgong in the Brahmaputra valley and the semi-independent State of Manipur. The approximate area is returned at 6400 square miles. The population is variously estimated at from 94,380 to 120,000 souls. The administrative headquarters are at the station of Kohima. Physical Aspects. - The District forms a wild expanse of forest, mountain, and stream, which has up to the present date been only imperfectly explored. The valleys as well as the hills are covered with dense jungle, and dotted with small lakes of deep water and shallow marshes, which all contribute to engender a very virulent type of malarious fever. It is estimated that virgin forest covers an area of about 2800 square miles. A considerable tract, called the Námbar Forest, has recently been brought under the conservancy rules of the Forest Department; but the greater portion is still a pathless waste, the secure home of large game. The jungle products collected by the wild tribes comprise beeswax, a variety of cinnamon, several kinds of dyes, and various fibres which are utilized in weaving. The mineral wealth has not yet been fully ascertained. Coal is known to exist in several localities on the Rengmá Hills, and limestone is to be obtained along the banks of the Námbar and Jamuná rivers. Chalk and slate have also been found. It is rumoured that silver exists in the hills ; but the Nágás theniselves are indifferent to the value of any of the precious metals, or of jewels. Hot springs have been met with in many places. The wild animals include the elephant, rhinoceros, buffalo, wild ox or griyal, tiger, leopard, and many kinds of deer. Large fish of good flavour abound in the hill streams. The chief rivers are the DAYANG, DHANESWARI or Dhansiri, and JAMUNA, which all become navigable during the rainy season for small boats. Each of these has many hill streams for tributaries. The surface of the country has not sufficient inclination to discharge the entire local rainfall, which stagnates in a chain of marshes at the close of the rainy season. The principal hills are the RENGMA and BAREL ranges. The Rengmá range, situated in the west of the District on the right bank of the Dhaneswari river, attains an elevation of from 2000 to 3000 feet. It is covered with forest and underwood, and the slope is very steep. The Barel Mountains run up from the frontier of Cachar, crossing the District in a north-easterly direction. Their greatest height is at the
