364 Remarks on the Geology of Tavoy. 



As it was broken from a precipice close to greenstone, it may 

 possibly have suffered some change from coming in contact 

 with that igneous rock, and may not be a good specimen of 

 the formation to which it belongs. A little above the fords 

 at E, a precipitous hill comes down to the river, which shews 

 a perpendicular point of fifty or a hundred feet of slate, similar 

 to the specimen marked F ; south-east of this locality, the spe- 

 cimen G was taken from the banks of the river near the water's 

 edge. Passing on to Khat brook, we meet with the strata of 

 which H is a specimen ; and returning to the northern branch 

 of Pagayay river, where the stream passes between high rocky 

 banks, at the water's edge the specimen I was taken, and 

 fifty feet above that the one marked i. The strata of which 

 K is a specimen appears to be of considerable extent, and in 

 Khat brook the same rock shews itself somewhat modified, of 

 which k affords a specimen. The one marked k k is from a 

 locality a short distance south of k, on Da-thway-khyoung, 

 (knife- whetting brook). Those labelled L, M, and N, are 

 specimens of the rocks that shew themselves on proceeding 

 up the stream, at intervals of half a mile more or less ; while 

 I is from the banks of Young-byouk river, some twenty or 

 thirty miles south of L in the direction of the strata, and 

 apparently the same rocks. The specimen k I again is from 

 the hills south of I a few miles, and appears to belong to the 

 same series. Returning once more to Pagayay river, the 

 rocks that next shew themselves are represented by O, P, 

 and Q, which follow each other in quick succession, on a 

 lofty precipitous hill. On approaching the main range of 

 mountains, the rock of which R is the representative, shews 

 itself. The descent on the eastern side exhibits rocks from 

 which the specimens S, T, and U, were taken ; the moun- 

 tain appearing to be principally composed of the one repre- 

 sented by S, and thirty or forty miles south of this locality 

 the west side of this same range is formed of a precisely simi- 

 lar rock. Those marked V, W, and X, are from the horizon-
