In other wdrds, there wis an earth tremor for every 10 minutes of tho day every day. " Every day of the week the seismopragh records dozens of earthquakes in different pails of the world," was, -a' statement credited to Father Pigot. -Hie reference, he pointed out, was not to the Puverview seismograph's work only, hut to. shocks recorded by seismographs m observatories the world over. Included in the total, 100, wore, .shocks under the sen;; us well us on hind.
