Iii comparing the different stations of the NUgiris, it must be kept in view, that
in this part of India the temperature varies much less from north to south than
from west to east; for the mean of the year and, the cool season excepted, for all the
other months of the year, the thermic equator1 passes to the east of the Mlgiris in a
nearly vertical direction. The decrease of temperature2 with height is here more rapid (quite
isolated peaks excepted), and therefore more favourable to the erection of sanitaria than
any of the mountainous regions to the south of the Himalaya; and not only the higher
parts, but also steps of minor elevation, are topographically well adapted to settlement and
colonization. The jangels, even in the lower parts, are neither very dense nor do they cover
large tracts; altogether, the Nilgiris are not thickly wooded. Forests, luxurious and exten-
sive in the higher parts, fill but hollows and depressions of the mountain sides. Mists,
and even heavy steamy fogs, are not unfrequent in the rainy season; the eastern side
is less moist than the western; from the end of October to May a sky clear and nearly
cloudless is the rule; September and October are pretty irregular in the quantity of rain
they bring.
