GNEISSIC ROCKS. 49 



hence there are frequently small caves and overhanging ledges at the 



junction in the two rocks^ especially at the points

where cataracts fall over the scarps in the rainy 



season. One very fine example of this occurs on the north side of the 

 Tillar gorge^ a little to the north-west of Kolik (Koleek). The action of 

 the fall on the soft micaceous rock has eaten a large cave into the 

 mountain side just below the lowest trap flow. Thick jungle grows up 

 into the wide crescent-shaped mouth of the cave^ while the falling water, 

 as seen from the opposite side of the ravine, hangs like a waving silver 

 thread across the dark yawning space and falls among the trees below. 

 The basaltic cliff overhanging the cave is so sheer that it is probable 

 nothing can be seen of it except from the opposite side. I much 

 regretted that want of time prevented my exploring the cave itself, 

 when working on the northern side of the great Tillar ravine. It must 

 be a very interesting spot, and probably also a beautiful one. Many beau- 

 tiful clefts and gullies of great depth are to be seen in other places, as, for 

 instance, from the Parwar Ghat, one very fine example of which is here 

 figured (Plate I). 



Chloritic schists, generally of very delicate pale sea-green, are met 



with largely at many places in the Hunugund

schistose band, e. g., at Somulapur, ten miles south- 

 west of Mudgal, at Timapur (Teemehpoor) , three miles north-west of 

 Hunugund, and at various other places along its north-west extension. 

 Chloritic schists of similar pale color are also met with largely in the Bail 

 Hongul schistose band. Tliey occur interbedded with and passing into a 

 similar pale-green massive chlorite rock o£ semi-crystalline texture, which 

 in some places assumes in its weathered state a singularly trappoid 

 appearance. In other places this is the more general character, the wea- 

 thering bringing out the schistose texture of the rock. This rock has 

 been regarded by previous explorers as a true trap, but I think errone- 

 ously. From its position and mode of association with the schistose beds, 

 the passage into which is very frequently to be seen, it appears to me
