about 6 miles west of the town, but the greatest motion appeared 

 to be vertical or nearly so. Only one shock was felt. The earth 

 rumbling was not very noticeable owing to the rattling of the 

 building. No damage.

Prof. Holden reports two shocks of earthquake close together, of 

 intensity (V) of the R. F. scale. 



Time of the second shock 4.45.14 a. m. The duplex seismograph 

 gives a condensed tracing 4.5 mm. by 3.5 mm. The plate is not 

 orientated. Mr. Townley, who was photographing in the Crocker 

 dome at the time of the shock, noted the time (of the first 

 shock?) as 4.44.41, P. S. T.

Prof. Keep sends a tracing of the earthquake which occurred at 

 4.46 a. m., showing a displacement of the pen of 12 mm. in a 

 northeast and southwest direction, and 8 mm. in a northwest 

 and southeast direction.

A slight shock occurred at 4.48 a. m., giving a tracing on the duplex

 tremors covering an area 2 mm. in a north and south direction 

 by 1.5 mm. in an east and west direction. (C. D. Perrine.)
