I shall here enumerate, for comparison, my determinations of the

 distinguished by Mineralogists.

It will be, perhaps, asked ; is this Coal, of which the traces are pro- 

 bably widely diffused in our sand-stone range, likely to prove of any value, 

 or do these many indications afford any ground to hope for the discovery of 

 more extensive and profitable deposits ? To this it may be replied, that 

 the considerations on which are founded the hope of discovering, in the 

 neighbourhood of these mountains, the true Coal formation, are quite in- 

 dependent of its occurrence under this type and in this form. If any thing, 

 perhaps, they are rather unfavorable to the expectation of eventually dis- 

 covering beds of the true Coal formation. For it has been noticed, that in 

 those countries in which the Coal beds are most largely developed, as in Eng- 

 land, the traces of the mineral, in the superincumbent sand-stone, are rare, 

 if not altogether wanting ; while on the Continent, where the true Coal 

 beds do not occur, small seams or veins are frequently met with in this 

 rock. 



But taking into consideration the arrangement of the surface in India, 



and the fact, that we have a trough, or basin, as it were, situated between
