250 Notes on the Recent Earthquakes [No. 123. 



in my hand when it came on, and I started up and called out for assis- 

 tance, thinking the house was coming down. Every one about the 

 place felt it, and came running to me. I found that the south door 

 of the inner room, which I had bolted before I went to bed, had been 

 forced open by the bolt falling down. Indeed every thing in the house 

 shook, and I was very much afraid of its falling, after having read the 

 accounts from our Army near Peshawur. At that place, a number 

 of houses have been destroyed, and many lives lost, from the last 

 Earthquake. 



Although this shock did not last so long as the one of the 19 th 

 of last month, in my opinion it was much more severe for the time. 



The rate of propagation of this shock appears to have been great, since 

 no perceptible difference was observed in the times of its arrival at the 

 following places : Simlah and Mussoorie in the Himalayas, Deyrah in 

 the Deyrah Dhoon, Saharunpore, and Berkeri. There is, therefore, 

 every reason to think, that on this occasion the shock was propagated 

 after the circular method, as I have defined it above, and the nature 

 of the shock appears to indicate, that the seat of the disturbing force 

 was either within the rocky crust of the earth, or at a very small dis- 

 tance indeed beneath it. Such a supposition is necessary to account 

 for the peculiar "jarring" sensation characteristic of this shock. Its 

 effects appear to have been most severe at Deyrah, where a large house 

 is said have been split from top to bottom, but no particulars of this acci- 

 dent have reached me. I am somewhat disposed to think that the actual 

 force of disturbance was situated somewhere in the valley of Deyrah, 

 and propagated thence to the hills on one side, and to the plains on the 

 other ; a more extensive collection of facts would however be necessary 

 to give probability to this impression, and these have not in this 

 instance been collected. It may be stated, however, that all who had 

 experienced both shocks in this neighbourhood, concurred in opinion 

 that they came in different directions, and as the first was from West to 

 East, it is not impossible the second may have been from North to 

 South. The southern door of the inner room of the Berkeri Canal 

 bungalow, which is stated by Serjeant Petrie to have been driven open 

 by the shock, would on the above supposition receive the first impulse, 

 and the effect produced upon it, tends in some measure, to confirm
