The wooden house and outbuildings caught fire fast, blazed up, burned down, but the dome, built of lathe and plaster above a drum of brick, would not burn. What they did at last was heap up the wreckage of the telescopes, the instruments, the books and charts and drawings, in the middle of the floor under the dome, pour oil on the heap, and set fire to that. The flames spread to the wooden beams of the big telescope frame and to the clockwork mechanisms. Narrated by Stefan Rudnicki.
