An unusually heavy earthquake shock was recorded yesterday morning by the Seismograph Station at the University. The vibrations began shortly after 8.24, and at about 8.40 became so violent that the needles which record them went off the drum on which the record them is made and put the seismograph temporarily out of commission. A rough computation by Professor J. B. Woodworth '94 makes the distance of the earthquakes about 4470 kilometres from Cambridge, or about 2778 miles.
