Answer:
When a supplier, vendor or any other type of seller breaches a contract, the court will generally determine the compensation for damages according to the difference between the selling price and the market price. In this case, if the selling price of wood from Nine-Mile mine was equal to the market price, there is no damage suffered by the buyer (Lewis). The buyer can claim certain damages related to time wasted and other minor issues, but the real issue here is that Lewis can actually save money by not purchasing that wood.
All Lewis needs to do is go somewhere else and purchase the wood directly without spending any money in logging.
