EPICENTRAL AND SKVKHF.LY SHAKEN AREAS. 17 



All the evidence in his large compound unanimously shows that 

 the shock occurred along a line N.N.W.— S.S.E. and certainly eon- 

 fined between the limits N.W.— S.E. and N.N.W.— S.S.E. One 

 interesting fact is quoted : — a big wall and some smaller ones 

 coursing E.N.E. — W.S.W.. had loose mortar and bricks shaken from 

 the top, but these only fell on the N.N.W. side. There is an 

 entire absence of any local reason why this should be SO, but not a 

 brick or a piece of mortar were found on the ground on the south 

 side. 



There was no sound before the shock. During it a loud rumbl- 

 ing was heard, but this was only i\w to the straining of the 

 various buildings. He has heard exactly the same noise during a 

 subsidence due to brine pumping in Xorthwich. Cheshire. He 

 Supposes that many people will write of a great noise through being 

 unable to differentia to between the actual shock and its results. 



The shock was intense, and it required a considerable muscular 

 effort to stand. Many of the women employed at the works were 

 thrown to the ground and some afterwards vomited. All the 

 Europeans whom he afterwards met said that they felt ; rather 

 sick," not from fear but solely from the motion. He distinctly felt 

 the rise and fall in the ground similar to the sensation fell in a lift 

 but the alternations were very rapid. 



All falls of bottles, lamp globes, and crockery conformed with 

 the direction already given. Some of tin 1 machines in the works 

 were half emptied of molten paraffin, which could not have taken 

 place had they not inclined quite K> n — 20 from the vertical, and 

 vet they were not damaged. They rolled on their long bases and 

 inclined' N.N. W.—S.S.U. 



During the aftershocks, lie often watched the swinging of two 

 hanging lamps suspended in a bungalow, which is built on piles 

 on a slope so that the floor is from 1<S to 24 feet from the ground. 

 The lamps often attained a large swing from the vertical and the 

 direction was in everv case between N.W. — S.E. and N.N.W. — 

 S.S.E. 



In a later communication. Mr. Armitage again drew attention to 

 the fact that the shock was cut up into three distinct periods of 

 intense agitation of which the Last was much the greatest. At 

 first it was impossible to form any idea of the velocity, and it can 

 be beat described as the sensation felt in a big building in which
