66 GREAT EARTHQUAKE OF 1897. 



and 15th July. By the former date in many cases records had ceased to be kept 

 either on account of the great number or the fewness of the earthquakes, accord- 

 ing to the nearness or distance of the station from the epicentre, and before the 

 latter I had not been able to interest a sufficient number of correspondents to en- 

 sure an even approximately accurate record. 



The authority on which the record is based naturally varies largely in value, 

 but it has not been possible to indicate this in each case without making the list 

 one of unwieldy bulk. It may be taken, however, that in general the authority is 

 sufficiently trustworthy as to the fact of an earthquake having been felt, though 

 the times given vary much in their degree of accuracy. 



In the list I have given, first the approximate local time of the shock at its as- 

 sumed origin in about long. 91 E. ; then follow the stations from which it was re- 

 corded, or, in the case of the more extended earthquakes, such selection from them 

 as shows the extent of the shock. Immediately following the name of the place 

 is the time as given in the original record ; local time is indicated by the letters 

 a.m. and p.m., Madras time by the letter m., and in this case the twenty-four hours 

 system is used, i.e., 1 p.m. is 13 h., 11 p.m. is 23 h. 



The duration and nature of the shock have not been inserted, as it was found, 

 that, however useful this information was for comparison with other records of the 

 same observer, the standards of different observers varied so much that it was 

 impossible to compare the statements of duration or violence at different stations. 



In nearly every case there can be little doubt that the observations grouped 

 together do refer to the same earthquake. In a few cases where two or three 

 widely separated stations are grouped together on the ground of an approximate 

 accordance in time, it is possible that we have to do with two or three small earth- 

 quakes approximately coincident in time. In a large proportion of these cases the 

 identity of the shock can be established by reference to the records from the 

 central area.
