chunk: Chamberlain also realizes that the same seismic forces that caused the building to drop back into the past can also be used to return it to the present, but that doing so will require several weeks of intensive work by the building's inhabitants, and in the meantime they must concentrate on feeding themselves. Chamberlain convinces the president of a bank on the first floor that he can return them to the present, and together they are able to organize the other inhabitants into hunting and fishing parties.
  Two weeks later, Chamberlain is ready to implement his plan. He forces a jet of soapy water into an artesian well beneath the building, and this allows the pressure that has built up in the rock to be released. The building travels forward in time again, returning to the exact moment when it began to travel into the past.
