(2) Character of the Shock within Isoseist X. 



It seems likely from a general consideration of damage done and 

 reports furnished, that the earthquake motion which 

 destroyed the most of Dharmsala was a very complex 

 one. The inequalities of the surface, and the great damage on ridges, 

 spurs, steep slopes and convexities, seem to show that the motion at 

 these actual surfaces was a compound of molecular and molar motion : 

 that the waves belonged to that large, slow- travelling, semi-gravita- 

 tional class which become manifest when traversing loose superficial 

 material that has a low modulus of elasticity and numerous free 

 surfaces. Through such rocks, near the surface, the amplitude would 

 be gradually increased and with it the period, owing to the inferior 

 powers of resistance and recoil among the particles of these more or 

 less disintegrated and soil-cap covered localities. 



Being of this character it is evident that the sensible shock On 

 every spur and ridge and elevated plateau lost way by visible displace- 

 ment, disruption, crumbling, loosening and spreading out of the 

 superficial rock and soil-cap — for which there is considerable evidence 

 in the fissures in the hillsides and the special damage there done ;
