102 REPORT OF THE CALIFORNIA EARTHQUAKE COMMISSION. 
The solid friction was so strong that it rendered the pendulums almost aperiodic and 
masked the details of the motion; for this reason the seismogram is not reproduced. 
The first movement discernible on the east component is at 13" 39.7"; and on the north 
component at 13" 54". The total duration is nearly an hour.
