 The carcasses were sent overnight by goods trains with a central block of ice to be loaded on the "Dunedin", where they were sewn into calico bags and frozen.To prove the process, the first frozen carcasses were taken off the ship, thawed and cut.After 7 days of loading, the crankshaft of the compressor broke, damaging the machine's casing and causing the loss of the 643 sheep carcasses stowed.
