broken off the continuation ; between the rocks on the right and those 

 on the left, the latter are of course perfectly dry. The cleft in the rock 

 proceeds, according to the natives, to a considerable distance, till at 

 length, from the height and closeness of its high rocky walls, the rays 

 of the sun are excluded. Natives from superstitious motives dread ex- 

 ploring its recesses, and tell many incredible tales of the vengeance 

 with which the Genius Loci has visited intruders. The bottom of the 

 fissure is completely covered with water to an uncertain depth. Hun- 

 dreds of the finny tribe sport in the clear depths of the water, which I 

 could not persuade the guides to attempt to catch, as they hold them 

 sacred. 



Chinna Garhi. I now proceeded to the smaller spring, or the Chinna 

 Garhi. Here the water gushes in a small silvery cascade from a cliff 

 about 200 feet high into a deepish pool among the rocks below, disap- 

 pearing through a narrow cleft, probably a continuation of the principal 

 fissure, to re-appear in the form of a spring below by some fault or dis- 

 location in the strata. In the rains it cannot run off by this outlet as 

 fast as it collects, and a large deep bason is formed, as evinced by the 

 black ferruginous coating with which some of the rocks in the vicinity are 

 covered. The temperature of this pool I found to be 68.5°, three feet 

 below the surface; temperature of air in shade 80°; in sun 86°. The 

 dropping of the thermometer into the water disturbed hosts of the small 

 fishes that rose to the surface, evading all my efforts to catch them. 

 The water is remarkably transparent, sparkling, and agreeable to the 

 taste, probably from containing a large proportion of fixed air. 



The formation of the range in this neighbourhood is a reddish white, 

 and greenish sandstone, interstratified with shales of various shades of 

 purple and light green, and passing into quartz rock, or arenaceous 

 schists. Large cavities occur filled with beautiful crystals of quartz, 

 and a little hsematitic nodular and stalactiform iron ore. I observed a 

 furnace for the smelting of this at the foot of the range. The rocks 

 are distinctly stratified, having a dip towards the North and East, 

 varying from 12° to 6°. The joints dip about 70°, and are crossed by 

 others at nearly right angles, separating the masses into cubes and rhombs. 

 The ripple mark is seen very distinctly on the lamina of some of the 

 arenaceous schists. The soil is a light red, and sandy : the vegetation
