of 1897-8, due to the famous long-continued Leiter corner. _Sources of information._—The object of this chart, taken altogether, is to show the general law of market prices as governed by supply and demand from the actual facts in the market for wheat. The facts are taken from the best records available. The prices are from the daily record of the Produce Exchange of New York. The average price for the year and the fluctuations within the year are given for the period from September 1, when the new crop appears, to the August following, this being the period actually corresponding in market with a year represented by the crop figures. The estimate of the world’s crop since 1885 is taken from carefully prepared statistics in the United States Department of Agriculture. The estimates prior to that date do not include the entire world, because no statistics can be reached, but they do include the most careful estimates of all countries whose product entered into the world’s market. No effort has been made, for fear of complicating the chart, to show a similar correspondence between supply and price in reference to corn and oats. The tables following, however, give data for such comparison with reference to this country alone. The export of corn and oats has been too limited to play any great part in modifying prices.
