    Marcus Huling v. Isaac Craig.
    THE plaintiff had undertaken to carry a quantity of provisions for the troops, by water, from Pittsburgh to Fort Le Bœuf. When at Fort Franklin, he found French-creek so low, that he did not proceed further. The defendant was obliged, at a great expence, to employ pack-horses, to carry the cargo from Franklin to Le Bœuf. This action was brought for the freight from Pittsburgh to Fort Franklin; and, against this demand, the defendant set up the extra expence of land carriage from Franklin to Le Bœuf.
    
   President.

It must be impossibility, not difficulty, that will excuse from performance of a contract. If complete performance become impossible from a cause not within the power of man to control, the loss ought perhaps to be divided.
