The box was weighed as it was lifted. It weighed twelve and a half tons. It was known that the wood and iron of the box weighed six and a half tons. Jumbo therefore weighed six tons. Scotty and Bartlett had always thought Jumbo weighed six tons. But this was the first time Jumbo had actually been weighed mechanically. On Friday March 24, it took only eight minutes to lower Jumbo and his box to the "Assyrian Monarch".
