GULF OF SIAM-BANGKOK RIVER.
The following information relating to the rivers Bangkok and Tachin at the head of the gulf of Siam has been received from Navi- gating Sub-Lieutenant James S. Barrett, of H.M.S. Teazer, Commander Richard M. Blomfield R.N.
Variation 2° 10′ Easterly.
Me-Nam Chau-Phya or Bongkok River.-The look out house on the west point, and red house in the river given as leading marks have disappeared. The course given from the fishing stakes on Admiralty chart No. 999, is stated by the pilots to be one which would now lead a vessel on shore, the course steered by the pilots is about N.E. N., instead of N.E. by E., hauling gradually to the northward as soon as the west point bears N.W.
Tachin River. The mouth of this river lies about 20 miles to the westward of the Bangkok river, it was navigated for about 35 miles by H.M.S. Teazer, in November 1871; this river bas a similar bar to that of the Bangkok river, but the entrance is more difficult to distinguish, the land in the neighbourhood being low, and covered with trees.
In clear weather the high land of Bang-pasoi brought to bear E. by S., will lead to a position off the bar, which may be crossed on a N.N.W. course.
Tachin river has about the same general depth and is of the same general width as Bangkok river. The Teazer anchored off Maconchisi in latitude 13° 39′ N., and longitude 100° 11′ E., nearly 35 miles from the mouth of the Tachin. At Maconchisi are the new mills of the Indo-chinese Sugar Company, the sugar is at present sent in barges by canal to Bangkok, but it is expected that vessels will shortly navigate the Tachin river as easily as they now do the river Bangkok, whereby an expensive freight will be saved.
