Loading a Boiler (Embarquement d'une chaudière) 128 years old

A stationary camera placed amidships looks toward the round end of a 10- or 12-foot boiler that's been loaded onto the open deck. Three men climb down from atop the boiler and then remove their ladder. Four or five other workers tie the boiler down to the deck. Their pace is leisurely. In the background is a busy harbor.
