Rocks Campanile With Hand.

Elmer E. Hall, associate professor nia, stood at the foot of the 300 foot Campanile on the campus and with one hand shook the giant structure, says a Berkeley dispatch to the San Francisco Chronicle. Hall has seismograph records, photographs and a lot of data to prove that he moved the huge granite needle and Is prepared to lecture to his students as to how the trick Is done. He says; “I placed a delicate seismograph like those used to record earthquakes on the top of the tower. Then I went down to the ground and about once In a second I pushed my hand against the granite shaft. By applying this pressure in time with the natural period of the vibration of the Campanile I set the whole masß in motion, so that Its vibrations were clearly recorded by the seismograph.” .. The Campanile, .is regarded as a master-piece of earthquake resistive construction. Instead of being a rigid structure, it is built with cross bracing eliminated at alterhate stories. The result is that its vibration is like that of a steel rod stuck In the ground by one end. In an earthquake, It Is claimed, the Campanile will vibrate like a tree instead of breaking.
