FORESHOCKS AND AFTERSHOCKS. 369 



With the year 1907 comparative quiescence sets in and the few 

 shocks recorded more and more lose the aspect of genuine aftershocks. 

 We continue to have records from the Simla seismographs and from 

 Kulu wh ich occasionally synchronise ; but only very seldom, as the shock 

 of 13th April, are there any reports from outside of this region. 



Although it is probable that the hilly region of Kulu and Simla 

 will go on yet for some time yielding shocks that may have a connec- 

 tion with the big shock of 4th April 1905, yet as time goes on these 

 will be confused with local ones common to the region and distant 

 ones from other centres. No more reports therefore were asked for 

 after December 1907 unless anything out of the common occur- 

 red. The Kelvin Grove seismoscope continued recording up to the 

 end of April 1908.
