 in a caisson now a caisson is made out of iron and it looks pretty much like one of these giant cigar tubes you know like the fancy cigars come in the little metal tube right they put it in this tube and they had a steamship towing the obelisk in this caisson back to england and they hit a hurricane and in the middle of the hurricane this obelisk was going to sink i mean the obelisk shifted in the tube i mean it was a real drama story and they had to cut it loose in the hurricane
