or even to Colombo.
[Illustration: CURRENT IN THE S.W. MONSOON]
In the south-west monsoon the current changes its direction; and,
although it flows steadily to the northward, its action is very
irregular and unequal till it readies the Coromandel coast, after
passing Ceylon. This is accounted for by the obstruction opposed by the
headlands of Ceylon, which so intercept the stream that the current,
which might otherwise set into the Gulf of Manaar, takes a
south-easterly direction by Galle and Donedra Head.[1]
[Footnote 1: For an account of the currents of Ceylon, see HORSBURGH's
_Directions for Sailing to and from the East Indies, &c._; vol i. p.

There being no lakes in Ceylon[1], in the still waters of which the
rivers might clear themselves of the earthy matter swept along in their
rapid course from the hills, they arrive at the beach laden with sand
and alluvium, and at their junction with the ocean being met
transversely by the gulf-streams, the sand and soil with which they are
laden, instead of being carried out to sea, are heaped up in bars along
the shores, and these, being augmented by similar deposits held in
suspension by the currents, soon extend to north, and south, and force
the rivers to flow behind them in search of a new outlet.
[Footnote 1: Pliny alludes to a lake in Ceylon of vast dimensions, but
it is clear that his informants must have spoken of one of the huge
tanks for the purpose of irrigation. Some of the _Mappe-mondes_ of the
Middle Ages place a lake in the middle of the island, with a city
inhabited by astrologers; but they have merely reproduced the error of
earlier geographers. (SANTAREM, _Cosmog_. tom. iii. p. 336.)]
These formations once commenced, their growth proceeds with rapidity,
more especially on the east side of the island; as the southern current
in skirting the Coromandel coast brings with it quantities of sand,
which it deposits, in tranquil weather, and this being carried by the
wind is piled in heaps from Point Pedro to Hambangtotte. Hence at the
latter point hills are formed of such height and dimensions, that it is
often necessary to remove buildings out of their line of
encroachment.[1]
[Footnote 1: This is occasioned by the waste of the banks further north
during the violence of the N. E. monsoon; and the sand, being carried
south by the current,
