No. XL— NOTE ON AN INLAND SEA CAVE IN MUANG PRAN. 



In a countr}^ where such excessive upheavals of the earth's 

 crust took place in early geological times, and where we hav'e now 

 comparatively recent deposits lying close to the very oldest igneous 

 rocks, it is not surprising that some evidences have been discovered of 

 present day land movement. 



I have for some time held the opinion that the whole of this 

 Peninsula is graduallj'' tilting from East to West, and the following 

 note gives, I think, further strength to my theory. 



At Muang Pran, where I was surveying last season, there is a 

 hill known as Sam Roi Yot ( 300 Points ). It is an isolated mass of 

 limestone, rising vertically from the plain, at a distance of two miles 

 from the coast. Seen from a distance, it has all the appearance of an 

 island, the surrounding plain lying very low. On the seaward side 

 there are springs of fresh water, and the land is taken up with gardens. 

 On the land side is a large swamp, which dries up in the hot season, 

 leaving a winding ste^m of brackish water. The soil is salt and only 

 suitable for growing coconuts and long grass. At the southern end of 

 the mass, on the landward side, I found a cave and the general over- 

 hanging appearance of sea erosion on the rock. The cave is at present 

 well above the high water sea level, but was reached by the fresh 

 water flood of 1912. Viewed from the top of the hill, the ground 

 shows the distinct form of an old sea beach which is not now reached 

 by the high water spring tides. 



On the whole I conclude that Sam Roi Yot was at some not 

 very distant date surrounded by the sea, and what I observed tends to 

 show that the hill has risen. My conclusion is further strengthened 

 by the general silting up which is found upon the shore of this coast, 

 whilst the opposite coast in Trang does not show the same effect, but 

 appears r.ather to be sinking — thus showing a tilt of the Peninsula 

 towards the \^'est.

[Since we iiatnrally expect to find stream -erosion caves in limestone, it 

 should be carefully ascertained whether there are any traces of an old cave 

 stream. It would I »e interestinij^ also to learn if any other evidence is furl h- 

 coniiiig to support Mr. Mastennan's tiieory of this land movement. — Eds.]
