210 MINERALS COLLECTED 



felspar, in very large crystals ; in a mass of this, in the bottom of a ravine, 

 the rock was distinctly traversed thrice or four times by granite veins, 

 accompanied by as many heaves. The granite of the veins becoming 

 smaller-grained, and redder, as more recent. I do not recollect that the 

 veins had any mica, the chief ingredient was red felspar. 



The gneiss dyke, though the contact was not actually to be observed, 

 must have proceeded through the granite before it reached the bed of the river. 



Gohula is three or four miles up the river Pesh, from Nayakund. The 

 river is here again dammed up by a very extensive dyke of crystallized 

 lime-stone. Its colours are brilliant, chiefly red and blue, or grey veined 

 with blue, and is highly polished by the continued running of the waters, and 

 broken into singular shapes, and hollowed into deep cavities and fissures. 

 The stream, of the most transparent water, dashes through it in a narrow 

 twisted and obstructed channel, and ends in a large natural tank, worked 

 out of the marble by the river ; its depth we could not fathom, with the 

 means then at hand, and being shaded by luxuriant trees, and backed by 

 the fantastic shapes of the polished marble blocks, it formed a scene that 

 was highly beautiful. Behind (north) was an amphitheatre of hills, and 

 in front an open cultivated country. 



The left bank of the river is composed of decayed gneiss ; the right 

 bank of clay and a loose conglomerate of pebbles : the lime-stone occupies 

 the bed of the river only, and appears unattached to either side. 



Here, as at Kumdr'i, (No. 1. B.) the lime-stone, which is much the 

 same rock as there, passes into a quartz rock, coloured by manganese ore;
