A mill owner in nineteenth century England discovered that part of his mill, the crankshaft, was broken. The miller hired someone else, a carrier, to bring the crankshaft to Greenwich for repair. The carrier did not deliver the crankshaft on time, and returned it to the miller much later than expected. The carrier did not know, however, that the mill could not operate without the crankshaft, and that the miller lost a lot of money while the crankshaft was gone. The miller sued the carrier, but the court held that the carrier did not need to pay the miller for lost profits because the carrier did not know he could be responsible for these profits when he made the contract.
