with both theSiwaliks and the calcareous Jurassic beds. How this mass was originally-placed it is difficult even to conjecture with probability, but its presencemay be connected with the intense folding and distortion of the rockswhere the Paniala bluffs turn sharply to the north, and are traversed bythe bridle path used to convey water from the last-named village to thehill station. The cliffs in the limestone group at this place were estimated, partlyby the aid of aneroid readings, at from 800 to1,000 feet in height, most of this being a sheer ver-tical precipice, through beds not only presenting a very focus of plication,but so intensely faulted and crushed that a portion of the Siwalik rocks,once caught apparently in a minor oblique synclinal on the northernside of the main Nila Roh and Shekh Budm anticlinal axis, has beenwedged into a position along the upper part of the Khavuri ravine-actually underlying the Jurassic rocks on both sides of the stream.

The outlines approaching an observer are drawn thicker thanthose more distant; the figures are the same as in the section across thehill, previously given; lines of fracture are marked with the letter F, andthe large surfaces upon which the limestone (sectional) character is omittedare convex towards the spectator.
