how far that width is occupied by solid ore, or how much it is intermix- 

 ed with spar, talc and other matters*. Also, on the continuity of 

 branches of ore to a reasonable extent, or, on the other hand, on their 

 being short and occurring at considerable intervals. 



Again, the character of the lodes will have to be described, — whether 

 beds conforming with the stratification of the country, or veins travers- 

 ing the same. — Whether numerous, parallel to each other, or crossing. 

 — What their direction usually is by the compass. — Whether vertical, 

 or at what angle they deviate from being vertical. — Whether they are 

 rich at particular places, as where veins intersect each other. — What 

 is the character of the mineral matter, filling the lode where ore is de- 

 ficient. — Whether this character is different, when near the surface, or 

 when observed at greater depths. — What proportion of the lode appears 

 to be metalliferous, and what barren. 



Facilities for working. 



Many considerations come under this head — character and habits 

 of the natives — rate of payment for labor — state of roads and means 

 of transport — supply of timber and other articles required — means of 

 drainage, such as levels for obtaining adits — falls of water for machi- 

 nery — streams whether constant and sufficient. As no mining opera- 

 tions upon an extended scale can be carried on without a command of 

 cheap and good iron, I shall next advert to the mines and manufacture 

 of this metal, and point out the peculiar advantages possessed by these 

 mountains, over other parts of India, for improvements in that valuable 

 branch of the natural resources of the country.

It is almost unnecessary to refer to the following passage which 

 is inserted under the head of European correspondence, page 110, 

 volume I. of this Journal, but it is so apposite to my subject that I 

 must be excused for quoting it as it stands. " I spent some time in 

 Paris this summer and saw a good deal of M. Cuvier. I used the 

 freedom of mentioning your name to him and your desire of taking
