Mahadeo, whence the view is most commanding over the sea of 

 hills in Munipur, tells me that he could see the Mountain Peaks 

 nearer at hand and on the East heaving about, and that the noise 

 of falling rock was very loud, and continued long after the earth 

 had quieted down with him. The effects upon these hills are very 

 great ; ravines choked with rock and debris ; and one party of my 

 men out-poling, found the body of a fine stag, that had been killed 

 by the falling rocks when standing by the water-course. 



On the Diyung, its effect seems to have been very severe ; the high 

 steep banks of recent clays and sand gave way in many places, falling 

 into the river, the ground along the valley was much bent and the 

 houses, structures of poles and matting were in many instances 

 thrown over. 



On the peak of Sherfaisip (a trigonometrical station) 26 J miles almost 

 due west of this place another helitroper of this survey was stationed 

 on the 10th ; this peak is also like Mahadeo, situated on the North 

 Cachar range, and is one of its culminating points, 5,612 feet. This 

 man's account, is most interesting. He was on the peak by 

 himself, sitting at the station mark with his heliotrope, facing 

 east ready in case he was required to shew to Mahadeo ; all was 

 still, and he was likely to hear and notice any peculiar sound. He 

 says that about 15 or 20 minutes before the shock, he heard 

 the sound of a distant cannon (tope was the word used), as if fired 

 some 30 or 40 miles distant. Before the shock came on, he heard the 

 rumbling coining from the east, and when he felt it, he caught 

 hold of the heliotrope, but that the motion was so great, he was 

 thrown backwards. He distinctly says the motion passed away 

 towards Marangksi peak, situated W. N. W. from his station. 



Here we have, it is most interesting to find, two well selected points' 

 20 miles apart, situated nearly due east and west of each other ; 

 at the first the waves were travelling eastward, at the second 

 westward, this places the divergence of the forces between the two. 

 How far this line would extend to the northward and southward, we 

 have, or rather 1 have, no means of ascertaining with exactness, but 

 it must resolve itself into a line of initial rupture, the intensity 

 diminishing on either side. If my supposition, and what I shall 

 endeavour to shew be correct, that the initial force exerted by this
