NORTII ARCOT DISTRICT
of the Nilgiri District, Madras, situated in Ir° 22' N. and 760 45' E.,
3 miles from Coonoor. It gives its name to a valley on the Nilgiri
plateau in which a cordite factory has just been completed, designed to
supply cordite to the troops throughout India. It has been included
within the limits of the neighbouring cantonment at WELLINGTON.
The machinery is driven by electricity generated at the falls of Karteri,
3 miles off. A brewery and distillery stand close by, and the village
is rapidly rising in importance. The old road to Ootacamund runs
down the centre of the valley by the side of the cordite factory.

Arcot District, North (Arkti).-An inland District on the eastern
side of the Madras Presidency, lying between 12° 20' and 13° 55' N.
and 78° i4' and 79° 59' E., with an area of 7,386 square miles. It gets
its name from the fact that it originally comprised that portion of the
former Musalmdn Sfibah of Arcot which lies north of the Palar river.
The part to the south was added subsequently from the southern division
of the Subah. The name is supposed to be a corruption of the Tamil
dru-kddu (' six forests '), tradition stating that the country was once occu-
pied by this number of forests, in which dwelt an equal number of rishis.
On the north the District is separated from Cuddapah by a portion
of the Eastern Ghats, locally known as the Tirupati hills, from the
town of that name which lies at their foot. The
range is broken by a long valley running northwards Physical
into Cuddapah District. Advantage has been taken
of this gap by the north-west line of the Madras Railway, which passes
up it through the Ghats on its way to Bombay. On the west the District
runs up to the Mysore plateau. In the south-west, separated from the
Eastern Ghats by the fertile valley of the PALAR, is the detached group
of the JAVADI HILLS, well wooded and containing much game, which
divides the District from Salem and part of South Arcot. Along the
southern and eastern borders, adjoining South Arcot and Chingleput,
the country is flat and uninteresting. In the north-east the Nagari hills
are conspicuous, with high precipitous cliffs, the most important peak
being Nagari Nose (2,824 feet), in the Karvetnagar zanminddri over-
looking the railway. This hill is visible from the sea in fine weather
and is a recognized landmark. From all the ranges numerous small
boulder-covered spurs branch off towards the centre of the District,
and combine to render it one of the most varied and picturesque
areas in the Presidency.
None of the hills is particularly lofty, the general elevation of the
Eastern Ghats and the Javadis being about 2,500 and 3,000 feet
respectively. The highest peak is Avalapalle Drug (3,829 feet), in
the Punganuru zanmnddri. Carnatikgarh (3,124 feet) in the Polur
