T. SPRATT ON THE COAL-BEARING DEPOSITS NEAR EREKLI. 



already been worked as far as practicable, and few extended a 

 greater distance before a fault was met with ; and as the seams 

 corresponded on both sides of the valley the same difficulties also 

 occurred in respect to the frequency of faults in both. One of them, 

 on the west side, that had been so worked out, Mr. Barkley informed 

 me, was found to be bent both downwards and upwards, as well 

 as being partly horizontal in the central portion, somewhat in this 

 form : —

On the west side of the valley the coal-seams were not so plainly 

 seen cropping out at the surface, nor so numerous as in the eastern 

 ridge, where there were no less than eleven or twelve seams thus 

 existing, of varying thickness and quality. 



The extent in which this number of beds or seams occur on the 

 east side of the valley is about two miles ; the seams being inter- 

 stratified with shales, sandstones, and conglomerates of quartz- 

 pebbles, with thin bands of clay occasionally, and also with thin 

 bands of ironstone, the whole comprising a considerable thickness 

 of these Coal-measures. See following sketch section : —
