APPENDIX III.
NOTES TO THE TABLES.
TABLES OF PRICES OF WHEAT AND OTHER, ARTICLES.

The Prices quoted in these tables are in all cases averages for the calendar year, and are reduced to gold where necessary. The grade of each article is, as near as may be, the same for the whole series of years covered by the tables.
Chicago prices are annual averages from weekly highest and lowest quotations given in the Reports of the Chicago Board of Trade.
New York prices of farm produce are the annual averages given in the Reports of the New York Produce Exchange (wherever those reports give annual averages).
The figures for British wheat are the Gazette Annual Averages. Those for the English price of American No. 2 Red Winter are taken from the tables of Mr. Augustus Sauerbeck, and are presumably averaged from the quotations in Mark Lane. In converting English into American terms, the penny has been rated at two cents, and the quarter at 504 pounds for British and 496 pounds for American wheat.
Of the prices of staples, iron products are given as quoted in the Statistical Abstract of the American Iron and Steel Association; wool, cotton, sheetings, prints from the Statistical Abstract of the United States; sugar, coffee, molasses, from the reports of the New York Chamber of Commerce, except that for some of the earlier years the price of sugar is taken from the reports of the Boston Board of Trade; leather, linseed oil, codfish, are from the reports of the Boston Board of Trade down to 1883; after that date from figures furnished me, very kindly, by Mr. Avery L. Rand, Secretary of the Boston Chamber of Commerce, the figures given for the last three articles being in each case the mean of the yearly highest and lowest, and not true averages; salt, from annual averages of prices quoted at the salt works in Syracuse, New York, which I owe to the courtesy of Mr. Thomas Molloy, Secretary of the Onondaga Coarse Salt Association.
