does not, however, extend to the very foot of the hills, as it is
considered imprudent to sleep at this season in the bungalow of
Terrya, only three miles off.

The elevation of Pundua bungalow is about forty feet above the sea,
and that of the waters surrounding it, from ten to thirty, according
to the season. In June the mean of the barometer readings at the
bungalow was absolutely identical with that of the Calcutta
barometer, In September it was 0.016 inch lower, and in November
0.066 lower. The mean annual temperature throughout the Jheels is
less than 2 degrees below that of Calcutta.

Terrya bungalow lies at the very foot of the first rise of the
mountains; on the way we crossed many small streams upon the
elephants, and one large one by canoes: the water in all was cool*
[Temperature in September 77 degrees to 80 degrees; and in November
75.7 degrees.] and sparkling, running rapidly over boulders and
pebbles. Their banks of sandy clay were beautifully fringed with a
willow-like laurel, _Ehretia_ bushes, bamboos, palms, _Bauhinia,
Bombax,_ and _Erythrina,_ over which _Calamus_ palm (rattan) and
various flowering plants climbed. The rock at Terrya is a nummulitic
limestone, worn into extensive caverns. This formation is said to
extend along the southern flank of the Khasia, Garrow, and Jyntea
mountains, and to be associated with sandstone and coal: it is
extensively quarried in many places, several thousand tons being
annually shipped for Calcutta and Dacca. It is succeeded by a
horizontally stratified sandstone, which is continued up to 4000
feet, where it is overlain by coal-beds and then by limestone again.
