Siam proper extends from about the latitude of 23° north, to the gulf of that name, and is bounded, west by the Burman empire, and east by the Lao (Lau) mountains. This is the valley of the Menam, the “Mother of waters,” the country of the true Siamese. The Menam, after watering the low, flat land, by its annual deposites, empties itself, by three channels, into the gulf of Siam. The boundaries of the Siamese dominions on the bay of Bengal, extend from the Burman, (or more correctly speaking, in the present day,) the English Burmese dominions, as far south as the boundary line between the petty states of Perak and Quedah, in the straits of Malacca, in about the latitude of 5° north, in which is included the valuable island of Junk, Ceylon or Salung, containing a vast body of tin ore. It then extends nearly east, across the Malay peninsula, in about the same latitude, between the provinces of Tungano and Pakhang, the shores of which are bathed by the China sea: it then extends north to the head of the gulf of Siam. The Siamese government, during the year 1832, brought under their immediate subjection, nearly the whole of the tributary states in the Malay peninsula. They possess, also, a large part of the late kingdom of Lao, including the former capital of the empire, called Lau-chang, situated on the great river Camboja, in about the sixteenth degree of north latitude, and which is represented to be very populous. They hold also (with the exception of a small portion of the southern part) the province of Batabang, in Camboja. Their eastern boundary line is in about the longitude of 105°, and extends north to the latitude of 15°, being the dividing line between Lao and Camboja, and extending south to the Siamese gulf, the boundary being the island of Kong, (alias Ko Kong,) situate in north latitude 10° 43′, and longitude 103° 17′ east. Extending north, on the east coast of the gulf, lies Chautabun, once a part of the ancient kingdom of Camboja. It is well known as a rich and valuable possession of Siam.

The Siamese possess no ships of war, but they have an immense number (probably not less than five hundred) of war-canoes; some of them being over a hundred feet in length, and made of a single teak-tree: they have also, probably, fifty or sixty vessels, having two or three masts, using fore and aft sails, and carrying from three to eight brass guns: the largest do not exceed a hundred tons’ burden: these are neatly and strongly built, and many of them are even elegant models. The whole number of mariners employed in foreign and coasting voyages, may be fairly estimated as amounting to not less than thirteen thousand.

PRODUCTS—IMPORTS.

Siam is a very fertile country, and abounds in productions suited for foreign trade, beyond any other with which I am acquainted to the eastward of the cape of Good Hope. It is no less distinguished for the variety and abundance of its mineral, than it is acknowledged to be for its vegetable productions. I have annexed a statement, showing the exports of 1832, the quantities of each article, the prices, &c., &c.

To the Siamese trade may be added that of ship building, which is carried on very extensively. A great number of Chinese junks are built here annually; the timbers are of a very hard wood called marbao, and the plank is of the finest teak in the world. Many of these vessels are of a thousand tons’ burden.

The imports consist of British piece goods, white and printed, with some woollens. India goods, of all descriptions, the coarser from Bengal, and the finer and more expensive, from Surak. From China are brought silks and teas, porcelain, quicksilver, and almost every other article exported from that country. From other sources powder, arms, and cannon; glass ware, and crockery; cutlery; some drugs; arrack; wine, &c., &c. Opium is strictly prohibited; but the Chinese and others introduce, clandestinely, large quantities for sale. There is an immense trade carried on at the capital, called Si-a-Yuthia, (pronounced See-ah-you-té-ah,) and on the opposite, or right bank of the river, at Bang-kok.

Cotton twist is daily increasing in demand, more particularly low numbers, from twenty to thirty. Twist, of a bright red, (not narrow,) from number forty to fifty, always sells well; yellow and green are died in the country, as well as ordinary red. Not more than twenty peculs should be sent by one vessel.

Siamese dresses should be of small star patterns, on red, blue, and green grounds, with a few chocolate grounds: the red grounds must be bright; they should be in the proportion of four to one of the others. Each case should contain twenty corges, containing four hundred dresses.

Prints, generally called seven eighths, find a ready market. They must be all of the star pattern, bright ground and narrow. The proportion is, two pieces of red to one of black or blue, in a case of a hundred pieces. Some on cloth, of thirty-four to thirty-six inches, would also sell.

Chintz. Large pattern furniture chintz is saleable. It is used for curtains and screens. Patterns running lengthwise, are preferred.
