The river Menam (or Meinam) is formed by the union of streams from the north. About halfway in its course mountains close upon the river, which passes from the upper plateaux of Laos into the valley of Siam proper through some of the finest mountain-scenery in the world. The rich alluvial plain of Siam is estimated at about four hundred and fifty miles in length by fifty miles average breadth. The main stream, above Rahany, is known as the Maping. Below the rocky defiles the river divides several times, and contains some larger and smaller islands; Ayuthia is built on one of the latter. The founding of this city, about 1350 A. D., was one of the most memorable events in Siamese history. In 1766 the Burmese depopulated the country and burned Ayuthia. A new dynasty, with Bangkok for the capital, was founded about a century ago. Bangkok, sometimes called “the Venice of the Orient,” is the Siamese metropolis――the first city in size, wealth and political importance. Old Bangkok is changing rapidly. European fashions and architecture are introduced among the nobility and wealthy. The new palace is a mixture of European architectural styles, retaining the characteristic Siamese roof. The furniture is on a most costly scale, having been imported from England, it is stated, at an expense of some seventy-five thousand pounds. The large library is filled with books in several languages and furnished with all the leading European and American periodicals. The royal guards are in European uniform, but barefooted, only the officers being permitted to wear boots. In the surrounding area are courts and rows of two-storied white buildings, the barracks, mint, museum and pavilions. The entrance to the throne-room is up a fine marble staircase lined with ferns, palms and plants. The throne-room is a long hall hung with fine oil paintings and adorned with costly busts of famous personages. The spacious drawing-room adjoining is furnished in the most luxurious European style. [Illustration: RUINS OF A PAGODA AT AYUTHIA.] The palace of the second king (named George Washington by his father, who was a great admirer of our celebrated American statesman) is also European in many of its appointments, with mirrors, pictures and English and French furniture. This prince, still in the prime of middle life, devotes a great part of his time to scientific pursuits, and has collected in his palace much machinery, including a small steam-engine built by himself. He is fond of entertaining European guests in European style; his reception-room is brilliantly illuminated with innumerable little cocoanut-oil lamps.
