SKETCH OF THE 



actynolite, with other minerals usually found associated with the granitic 

 rocks, complete the list. The metals are iron, copper, and lead, with 

 which last silver appears sometimes to be associated. The iron is very 

 abundant in many situations — and there are several founderies for this 

 metal. Copper does not appear to be very plentiful, but may be detected 

 in many of the soft bluish varieties of argillaceous schist. On digesting 

 a mass of this rock in nitric acid, a steel rod plunged in the fluid 

 acquires a coating of copper. There is a lead mine at the village of 

 Joivar ? twelve miles south of Udayajmr, which occurs in a series of alter- 

 nations of quartz rock and argillaceous schist, and it is said that a con- 

 siderable proportion of silver was found combined with this metal, which 

 was worked at one time to considerable advantage. Were this country 

 properly explored, I have no doubt but that many rich mines might be 

 discovered. 



A country where such a diversity is perceived in the nature of the 

 rocks must, necessarily, present a bold and striking appearance, and in 

 accordance with this diversity, we observe a corresponding difference in 

 the shape of the hills, — the harder and more durable rocks appearing, as 

 it were, to penetrate through the substance of the softer, and rising in the 

 form of peaks, denticulated ridges, &c. From the extensive distribution 

 of the quartz rock, and from its hard and durable nature, many very 

 striking appearances are exhibited. It is sufficiently obvious, when 

 a hard rock is associated with one of soft and less durable nature, 

 that in the course of time the former will occupy the highest posi- 

 tion, whatever might have been its original situation. This, then, is 

 the case when the quartz rocks are associated with the softer argil- 

 laceous schists. The latter gradually crumble away, and leave the 

 former occupying the summits of the hills, and presenting different 

 aspects according to the nature of the quartz and the breadth of its
