SKETCH OF THE 



of the many bountiful arrangements which Providence has made to sup- 

 ply the wants of its creatures. Many of the wells at Nasirahad are 

 eighty feet deep, and are bored through the solid rock — the water in these 

 is generally hrackish — and is impregnated with saline ingredients. The 

 hill fort of Hamirgher, situated twenty-one miles north of Chitor, is 

 remarkable on account of a well which has been bored, with infinite labour, 

 through the solid rock from the summit to the very base of the Iom^ hill 

 on which the fort is situated. This well is nearly two hundred feet deep. 



During the rains, springs of water may be seen, in many of the hiily 

 districts, issuing from the rocks at the surface. 



^- , In the north of Ajmer and Jaypur, the water is bad and brackish. 

 In the southern districts it is excellent; and the only foreign ingredient 

 which I have as 3'^et detected in it is carbonate of lime, which sometimes 

 exists in considerable proportion. A quantity of carbonic acidgass, in a 

 free state, must, of course, exist in these waters, to enable them to hold 

 the carbonate of lime in solution. 



With regard to the Geology of the primitive portion of the district to 

 . the west of the central range, I can say nothing. My specimens from the 

 Serooee district are as follows, and these indicate a similar variety of 

 rocks to those which we have described as occurring to the east of this 

 range : 1st, a rock composed of pure black shining hornblende without 

 intermixture ; 2d, nearly the same as the above, but with associated 

 felspar in small proportion ; 3d, a sienitic granite, approaching to primi- 

 tive greenstone ; 4th, a granitic rock, composed of flesh-colored felspar, 

 with a distinct foliated fracture, quartz in much smaller proportion, and of 

 a white color, and steatite — 'the last in very small quantity, and in other 

 specimens of the same rock entirely wanting — this granite is very large
