 244,C00 square miles in extent. Parts of seven 

 states and a small section of Mexico are em-

 of water contributed to the discharge of the 

 liver by the several states and by Mexico beats 

 no definite relation to tlie extent of watershed 

 in each. This will be seen from the followin;^

 River and its tributaries is indicated hx the
