'I'wo other articles in the same magazine deal with 

 the times at which the disturbance was recorded by 

 seismographs. From them we gather that the shock 

 was recorded on a self-registering seismograph in the 

 University of California at sh. 12m. 38s. a.m. Pacific 

 time, equivalent to ih. 12m. 38s. p.m. Greenwich 

 time. The seismograph of the United States Weather 

 Bureau at VVashington, 2435 miles distant from San 

 Francisco, recorded the commencement at 8h. 19m. 2_os. 

 eastern time, corresponding to ih. iqm. 20s. Greenwich 

 time, and the seismographs of the United States Coast 

 and Geodetic Survey at Sitka, Alaska, and Chelten-

 at ih. i6m. 56s. and ih. 19m. 24s. respectively, the 

 distances from .San Francisco being 1455 and 2450

 at Baldwin, Kansas, were also affected by the passage 

 of the earthquake waves, the times corresponding 

 approximately with those of the arrival of the principal, 

 or third, phase of the disturbance.
