The following data reflects the movement from region to region of a commodity by tonnage. In order to protect the confidentiality of the data provided by individual companies, the following procedures were implemented. PROCEDURE 1: Specific commodities were changed to more general categories. For example sugar becomes labeled as "Food and Food Products, " sulphur becomes "Chemicals excluding Fertilizer, " and gasoline becomes a "Petroleum Product." PROCEDURE 2: If three or more vessel operating companies do not carry a particular commodity from a region of origin to a region of destination, then that commodity is reclassified to "Unknown and Not Elsewhere Classified Products. " For example, if only two companies carry farm products from the Tennessee River to the Arkansas River, the tonnage for those farm products would be classified under "Unknown and Not Elsewhere Classified Products.
