The best examples of these are furnished along the great stretch of 

 plain country within the neighbourhood of isoseist No. 7, and lying 

 between Lahore and Saharanpur, a stretch of country which includes 

 many important cities that are also railway centres connected by the 

 main lines of railway in this part of India, and for which therefore 

 accurate time would be a natural desideratum. Certain other centres 

 of importance, such as Simla (the summer head-quarters of the Govern- 

 ment of India) and Mussoorie and Dehra Dun, also exemplify the same 

 thing, and make it abundantly clear that uniformity in the times recorded 

 is primarily dependent on the places being of such importance in the 

 official or commercial world that regular time-keepiog may be presumed 

 to have begun to be more or less a reality.

Although it may be that the last value is the most correct, we see 

 from the above only a variation of half a minute in all times that have 

 been substantiated by reference to a fixed standard. 



1 The Fame fact is very noticeable in the case oi the severe aftershock of 

 28th February 1906 where such times could be compared with those of the seis- 

 mographs which were Ihen installed at Simla. 'See page 366.)
