NAZIRA FIELD. 78 



On the Namsang-Giliki path^ a little below the village, there is 

 a thin seam at an elevation of 2,000 feet above the plains. 



The bed examined by Mr. Thornton in 184.8 is situated in this 

 neighbourhood at an elevation of 1,400 feet. He describes it as 10 

 feet thick, including 3 to 4 feet of good coal, dipping at about 35°. 



The principal known seams, then, below Namsang contain the 

 following thicknesses of coal : —

No. 1 and the upper part of No. 3, being perhaps the same bed, 

 and inferior in quality, may be excluded from the list of available 

 seams, leaving four workable ones containing about 17 feet of coal. 



As in the cases of the other fields, the data are insufficient for 

 Quantity of available forming an estimate of the total quantity of 

 SafErai. available coal, although they will serve to show 



that a large quantity may be depended on. In the Saffrai, the mea- 

 sures are known to extend from north of the Chota Taukak to south- 

 south-east of Tirugaon, a distance of about 4| miles. In the northern 

 part of this area the known workable seams are respectively 4' 0", 5' 1" 

 9' 0", 18' 0% and 37' 6" thick, containing a total of 73 feet 7 inches. 

 South of this the ground is obscured by alluvium, and in the southern 

 part of the area only one workable seam is known, which contains 33 

 feet of coal. The mean of these numbers gives an average of about 

 17 yards. As the coal is altogether below the alluvium level, 150 yards 

 (equal to a vertical depth of about 350 feet with a dip of 50°) is per- 

 haps as great a depth as can be safely taken to be within practical reach.
