Mekhong, or MEKONG (also called Cambodia), the greatest river of the Siam peninsula, since 1894 mainly controlled by the French (see SIAM), is usually identified with the Lan-tsan, which rises in the neighbourhood of Chiando in Tibet—its exact sources are not known. It pursues a generally southerly direction to the China Sea, which it enters by several mouths in Cochin-China. This country indeed is formed by its deltaic deposits. The river has a total length of 2800 miles; but is not navigated higher than 14° N. lat. owing to rapids and cliffs which beset its bed in the mountainous regions.
