(1) Tai O as a fishing port.

Tai O owes its growth as a fishing port to its position and site. It is situated on the west coast of the Colony protected from the prevailing easterly winds. Access to the sea for fishing is easy. At the estuary of a river, safe". anchorage is provided by the several creeks. The va ley floor offers flat land for settlement and fresh water for drinking and domestic purposes is readily obtainable from the streanu. Arable land and salt pans are close at hand, provi- ding jobs for the fishermen's families. In addition, salt from the salt pans facilitates the fish-pre serving industry.

The villages to the south of Tung Chung Bay have developed into farming settlements for the following reasons. This is a comparatively extensive and flat valley floor under 50 metres, Sever al streams flow through the region. Soils deposited are alluvial in nature and therefore fertile.

The distribution of monsoon rainfall is closely related to the relier of an area, Areas of high relief on the windward slopes

of mountains receive heavy rain. The onset of this kind of rainfall is fairly abrupt, de- pending on the arrival of the monsoons. Rains fall is thus unreliable and variable. With the outburst of the monsoons, torrential downpours BTS" COMMON.
