Of the tributary states, the Laos, who occupy the Mekong valley and spread themselves among the wilds between Tongking, China, and Siam, are probably the least known. In physique and speech they are akin to the Siamese, and are regarded by some writers as being the primitive stock of that race. They have some claims as a people of historical importance, constituting an ancient and powerful kingdom whose capital Vein-shan, was destroyed by Siam in 1828. Since then they have remained subject to Siam, being governed partly by native hereditary princes, duly invested with gold dish, betel-box, spittoon, and teapot sent from Bangkok, and partly by officers appointed by the Siamese government. Their besetting sin is slave-hunting, which was until recently pursued with the acquiescence of the Siam authorities, to the terror of the hill-tribes within their reach and to their own demoralization. Apart from the passions associated with this infamous trade the Laos are for the most part an inoffensive, unwarlike race, fond of music, and living chiefly on a diet of rice, vegetables, fruits, fish, and poultry. Pure and mixed, they number altogether perhaps some one million five hundred thousand. The most important of the Malay states is Quedha, in Siamese Muang Sai. Its population of half a million Malays is increased by some twenty thousand Chinese and perhaps five thousand of other races. The country is level land covered with fine forests, where elephants, tigers, and rhinoceroses abound. A high range of mountains separates Quedha from the provinces of Patani (noted for its production of rice and tin) and Songkhla. These again are divided from the province of Kalantan by the Banara River, and from Tringann by the Batut River. In Ligor province, called in Siamese Lakhon, three-fourths of the population are Siamese. The gold and silver-smiths of Ligor have a considerable reputation for their vessels of the precious metals inlaid with a black enamel. As to the Cambodian provinces under Siamese rule the following particulars are extracted from a paper by M. Victor Berthier: The most important provinces are those lying to the west, Battambang and Korat. The former of these is situated on the west of the Grand Lake (Tonle Sap), and supports a population of about seventy thousand, producing salt, fish, rice, wax, and cardamoms, besides animals found in the forests. Two days' march from Battambang is the village of Angkor Borey (the royal town), the great centre of the beeswax industry, of which 24,000 pounds are sent yearly to Siam. Thirty miles from this place is situated the auriferous country of Tu'k Cho, where two Chinese companies have bought the monopoly of the mines. The metal is obtained by washing the sand extracted from wells about twenty feet deep, at which depth auriferous quartz is usually met, but working as they do the miners have no means of getting ore from the hard stone.
