GEOLOGY OF CENTRAL INDIA. 89 



Regarding the metals of this district I can say but little. Dur- 

 ing the past cold season, I had proceeded as far as Nasirabad, for 

 the purpose of examining the Jjmer lead mines; but the sudden 

 calls of duty obliged me to return to Udayapur, when I was on the very 

 point of setting out on my intended excursion. I can, therefore, give 

 no additional information to what is already known respecting these 

 mines, — and I must be satisfied with remarking, in a general way, 

 that iron, copper, and lead, with which last silver has occasionally been 

 found associated in small proportion, are the only metals which have as 

 yet been found in this district. Several specimens were shown me as ores 

 of antimony. These were, however, well-marked galena. There are 

 several iron founderies in this district, and this last metal appears to be 

 very abundant in the quartz rock formation. Copper mines, too, have, I 

 believe, been worked near Mandal, in Mewar. 



Several simple minerals have been mentioned as occurring in the 

 granitic rocks, &c. ; and in one variety of granite was observed a mineral 

 which appeared to me to be Saussurite. 



The depth of the wells in the /primitive portions of Central India 

 appears to depend, in a great measure, on their being near, or at a dis- 

 tance from — the large lakes Avhich abound in this district, and the remark 

 first made by Shah Baber, (see Leyden, and Erskine's translation of 

 his life,) who appears to have been a wonderfully intelligent observer of 

 nature, I have found to be perfectly correct. This remark is, that in the 

 apparently dried-up courses of rivers and nullahs in India, water is uni- 

 versally found close upon the surface, and that, even during the hottest 

 periods of the year, it is only necessary to dig a few feet through the sand 

 to reach it. We cannot but agree in the reflection made by this monarch 

 upon stating the circumstance ; viz. that it presents an instance of one
