And after testing May 31, 1859 the bell
was taken to the building of the Parliament with the enthusiastic cheers of the crowd.
However, after 2 months the bell cracked to a huge upset of Denison. Weight of the hammer which beat the bell, was twice as heavy as the maximum possible weight of the hammer defined by George Mears.
During 3 years the bell was inactive, and instead beat off hours bell, responsible for a quarter of an hour.
Later there was made easier bolt , but the crack is still making its presence felt in the world famous chimes.
