34 MIDDLEMISS: PHYSICAL GEOLOGY OF SUB-HIMALAYA. 



ft. trtg. 1 Here there is a steep scarp on the left bank of the river 

 showing a gradual inclination of the beds S.S.W. The increase of 

 dip can be watched, step by step, as it gradually achieves the angle 

 of 40 , which sinks again to 30 near where the stream issues into 

 the plains. At several points along the river-bed Recent deposits of 

 calcareous tufa are seen in small quantities, formed by a constant 

 dripping of the water from the banks above. 



The upper reaches of this stream show horizontal conglomerates 

 similar to those just mentioned. No deflexion

in the steep scarp near Okjalu pani, nor under 

 Mania tila. This horizontality continues down stream until about 

 I mile of the outlet. Numerous good exposures then show a gradual 

 bending over towards the S.S.W. and S. There is nothing that can 

 be construed as an unconformability between the horizontal beds 

 and the inclined ones ; nor is there any distinction between the 

 material forming either set of beds. The dip increases gradually, 

 the increase being measurable degree by degree, until at the outlet 

 by Komola the beds are vertical, striking E. — W. very nearly. For 

 about two miles up this stream the left bank is flat and low, being 

 covered with recent alluvium composed of fine clay, and with very nu- 

 merous deposits of calcareous tufa. 



Except for the last mile or so down stream, the conglomerates 



here are perfectly horizontal. A gradual dip

(or 8o° N.N.E. inverted). At the south entrance to this stream 



I very nearly made a mistake of interpretation, which is sufficiently 



instructive in itself to be mentioned. Just at the point where both 



sides of the stream rise into steep banks, the right bank for some 



distance shows inversion to the north, which gradually becomes 



vertical in 20 or 30 yards of exposure up stream. The cliff 



showing this is about 20 feet high, but the upper 15 feet are
