386 Dr. Heifer's Report on the [May, 



red or ochry, by the abundance of iron oxyde with which it is im- 

 pregnated. 



The coal is visible either in its native locality on the side of a mon- 

 Locality of the sec- soon rivulet, or is to be found in pieces in the bed of 



tion lymg bare, ex- 

 tent, thicknes. the same rivulet. 



This deposit is neither covered with porphyry, nor red sandstone, 

 nor arenaceous beds belonging to intermediary formations ; above it 

 are only placed alternating beds of slate clay, either bluish grey or 

 whitish, either friable or compact, and then carburetted Brand-striefer, 

 and these strata taken altogether are not more than three and a half 

 feet in thickness, above which rest the above mentioned iron-tinged 

 earthy clay and alluvium. At this place the coal may be calculated 

 to be seventeen feet below the surface on an average. 



On the sides of this rivulet or channel, dug out by the impetus of 

 the water, a section is exposed of fifty-four feet in length, and the same 

 formation is traceable more than one mile to the north, and six west. 



The thickness of this coal stratum is as yet not ascertained, on ac- 

 count of the water accumulating in the rivulet, the rainy season 

 having begun ; but it must be considerable, as at a depth of six feet no 

 other alternating formation has been found. In consequence of this 

 the nature of the sub-stratum cannot be yet determined. 



This stratum runs nearly in a direct line from north to south, and 

 dips under an angle of 26° east to the horizon. In two places it is 

 contracted, in the rest uniform. 



It is difficult to classify exactly this coal, on account of its modi- 

 Mineralogical fications in different pieces. It belongs to the sub-genus 

 classification. ^lack coa ^ k ut there are several species even in the seven 

 tons which have hitherto been brought to light. 



Some pieces participate greatly of the character of Cannel-coal, these 

 having a resinous lustre and a flat conchoidal fracture; the pieces 

 nearer to the surface have again more of the character of slaty coal, 

 with a slaty fracture, fragments trapezoidal; the greatest number, how- 

 ever, hitherto observed refer it to glance coal, sub-species pitch coal, 

 being massive, in botryoidal loam, with a woody texture, fracture large, 

 perfectly conchoidal, fragments sharp-edged, unde terminated angular. 

 The dendritic texture is a peculiar feature of this coal, not observed 

 in any of the other coal species hitherto found in the Tenasserim 

 provinces. 



A hundred grains of the coal previously reduced to small pieces were 

 Chemical anal- placed upon a platina sheet, and put over a lamp fed 

 ysis of the coal. wifch a i cohol . on becoming red hot, they baked slightly 

 together, and on being removed from the fire assumed an iron grey co-
