272 APPENDIX. 



Nanera, yielding ore of the same quality and being of about equal extent in area. 

 A third area where similar ore, although here not quite so rich, is obtained, lies to 

 the east of the river Tawa, near the old and now abandoned village of Basnia. 

 This deposit is in places thicker than either of the others, being locally so deep 

 as 10 or 11 feet." 



" Other smaller deposits occur here and there filling small depressions on the 

 surface, and forming detached areas from which this iron gravel has been partially 

 exhausted. These are numerous, but of no great extent. Those mentioned by Mr. 

 Jacob, as occurring near Poonassa village, and which were opened during his visits, 

 have, I believe, been since abandoned, not proving remunerative." 



" In addition to these sources of ore, a regular vein or seam of rich specular iron 

 is worked near to the gravel deposit at Nanera. And this appears to me the most 

 valuable source of ore in the whole district. It is of variable thickness, from 2 feet 

 to 8 or 10, but of fine rich quality, and with very little admixture of any gangue 

 or stony matter." 



" The more easily extracted loose ores are preferred by the Natives ; their 

 wretched tools and appliances failing to make much impression on the harder and 

 more solid mass. The ore is extracted by little burrowings or holes sunk in the 

 deposits most carelessly constructed and most of which falling in during the rains 

 have to be entirely reopened for the succeeding year's operations. The ore in 

 these deposits has been derived from previously existing beds or veins,' which have 

 been broken up, drifted, and sorted, by the action of water, and arranged in 

 regular layers, where the greater specific gravity of this ore, compared with the 

 quartz and other ingredients mixed with it, has led to its deposition. They are, 

 in fact, in all respects analogous in their mode of deposition, arrangement &c, to 

 many deposits of Tin ore, and are nothing more than Stream-iron-works. .Nature 

 having thus already sifted these ores, and removed the greater portion of the 

 extraneous matter, they are necessarily more productive than the same ores freshly 

 extracted and mixed up with veinstone &c, would be. I do not at all doubt that 

 the specimen examined by Mr. Jacob may have yielded 60 - 4 per cent, of iron, but 

 this is certainly much above the average yield of the ore, which would not exceed 

 55 per cent." 



" Mr. Jacob mentions that the river Nerbudda cuts four large veins within the 

 short space of one mile, one of which is 122 feet wide. Accompanying this state- 

 ment there is no plan or more detailed description to shew where these veins occur, 

 but from the coincidence in measurement and from the absence of any thing even 

 so slightly agreeing with his description in other places, I conclude that he refers 

 to the part of the river Nerbudda immediately above the junction of the river 

 Tawa. In this place, several veins of a siliceous breccia with a ferruginous cement 

 cross the river, the largest of which coincides with the measurement given by 

 Mr. Jacob. If these be the lodes or veins referred to, I have no hesitation in 

 saying, that as practical sources of iron ore, they are utterly useless. That an iron 

 ore of good quality occurs in them is beyond a question ; but it is too sparingly 

 distributed in the mass, and the small bunches of it which occur are too few and
