The following description of the country is quoted with some emendations from Mr. Carl Bock's "Temples and Elephants." The European name for this land has been derived from the Malay word _Sayam_ (or _sajam_) meaning "brown," but this is a conjecture. The natives call themselves _Thai_, _i.e._, "free," and their country _Muang Thai_, "the kingdom of the free." Including its dependencies, the Lao states in the north, and the Malay states in the south, Siam extends from latitude 20° 20' N. to exactly 4° S., while, with its Cambodian provinces, its extreme breadth is from longitude 97° E. to about 108° E. The northern frontier of the Lao dependencies has not been defined, but it may be said, roughly, to lie north of the twentieth parallel, beyond the great bend of the Mekong River, the high range to the east of which separates Siam from Annam. To the south lie Cambodia and the Gulf of Siam, stretching a long arm down into the Malay Peninsula. On the west it abuts on Upper and Lower Burma, both now British possessions. Through Siam and Lao run two great mountain chains, both radiating from Yunnan through the Shan states. The eastern chain stretches in a S.S.E. direction from Kiang Tsen right down to Cambodia, while the western chain extends in a southerly direction through the Malay Peninsula. Their height rises sometimes to 9,000 feet, but it does not often seem to exceed 5,000; limestone, gneiss, and granite appear to form the main composition of the rocks. [Illustration: INUNDATION OF THE MEINAM.] Between these two mountain-chains, with their ramifications, lies the great alluvial plain of the Meinam, a magnificent river, of which the Portuguese poet Camoens sings (Lusiad X. cxxv.): "The Menam now behold, whose waters take Their sources in the great Chiamai lake," in which statement, however, the bard was misinformed, the source being a mountain stream on the border of the Shan states, but within Lao territory, and not, as is generally marked on charts, in Yunnan. Near Rahang the main stream is joined by the Mei Wang, flowing S.W. from Lakon, the larger river being called above this junction the Mei Ping. The other great tributary, the Pak-nam-po, also called the Meinam Yome, joins it in latitude 15° 45', after flowing also in a S.W. direction. To the annual inundation of the Meinam and its tributaries the fertility of the soil is due. Even as far up as in the Lao states the water rises from eight to ten feet during the rainy season. A failure of these inundations would be fatal to the rice crop, so that Siam is almost as much as Egypt a single river valley, upon whose alluvial deposits the welfare of millions depends. In this broad valley are to be found the forty-one political divisions which make up Siam proper.
