NOTE.-The Interstate Commerce Commission issued a statement Nov. 9, 1923, showing "Estimated freight revenue of Class I roads by classes of commodities on the basis of 1922 tonnage at 1923 rates."

The 1. c. 1. tonnage was 43,176,746; the carload tonnage, 979,932,832.

INDEX.

The numbers in the first column of this index refer to the pages in the text; those in the
second column to the paragraph or section of the tariff act of 1922. For commodities, the para-
graph of the tariff act is summarized in the table "Comparison of tariff acts," pages 865 to 980.
The text of the administrative provisions is given on the page indicated in the first column.

It was sometimes found impracticable to combine, in the dictionary, general economic dis-
cussions with the minute subdivision of the tariff law. The index is primarily a guide to the
tariff law, and, taken in conjunction with the alphabetical arrangement of the dictionary, should
enable the reader to find any subject treated.

The reference in the index to the paragraph of the tariff is merely a guide in finding the
law, and does not necessarily mean that the item enumerated will carry the stated rate. There
is lacking for many articles listed any authoritative decision of their tariff classification.
