It is obvious from these results that while this thick deposit contains some layers 
which are really good coal, there is also a large amount which is scarcely deserving of the 
name of coal at all. Stuff with 30 and 40 and even up to 47 per cent, of ash—useless 
matter—would he of no avail excepting for purely local demand in such work as lime-burning. 
&c„ while coal such as is represented by No. 13 or No. 30, or the bed A, would hold just com¬ 
parison with some of the best coals in India. Probably the fairest way. seeing that although 
the specimens are taken from about every foot, the actual matter assayed may really represent 
only an inch or two in thickness, is to take the whole as one, and take as the mean composi¬ 
tion the average of all the results (neglecting for the present the two separate 3 feet 
seams). Ami for comparison, to take 30 specimens of Ranigunj coals from different worked 
beds, and take the average composition of these. 
Taking the 31 specimens of the Googoos coal, the average result of all is— 
Carbon ... ... ... ... 44'51 
Volatile ... ... ... ... 35'34 
Ash ... ... ... ... 20-15 
And the average result of 30 Ranigunj coals is— 
Carbon ... ... ... ... 50'9 
Volatile ... ... ... ... 34'6 
Ash ... ... ... ... 14'5 
that is, the Googoos (average) coal is G'39 per cent, inferior to the average of Ranigunj 
coals as to the main heating power, and it is also 6 per cent, worse than the same as to 
amount of useless matter. Or, viewing it in another way, it may he said that ont of the 
31 odd feet of ‘ coal ’ there are 28, which contain less carbon than the average of 30 
Ranigunj coals, good and bad, and only 3 which contain more ; while there are 23 which con¬ 
tain more ash than the same average, and only 8 which contain less. 
These results appear unquestionable, so far as the coal yet obtained is concerned. That 
this coal will at the same time prove highly useful cannot for a moment be questioned; and 
we must only continue to seek for better. 
The results of these trials showed the duty of Chanda coal roughly, as compared with 
Ranigunj coal, to he as 67 to 87. The comparison by assay gives 45 : 51, or the trial by rail 
gives the work in the ratio of TOO : 1'29, that by assay as TOO : 1'14. As compared with 
English coal the duty was by actual trial as 4'0 to 6'5, by assay as 44'5 : 08, or, in the first 
case, as 1: 1'63, in the latter as 1: l - 53.
