Annual fluctuations in pork prices in Chicago—average of fifteen years
Average annual fluctuations.—This chart is intended to show the annual range of prices as shown by reports of the Board of Trade of Chicago, from September, 1883, to August, 1897. The figures, right and left, give prices per cwt. of live hogs, and per barrel of green hams and mess pork. The figures opposite the shaded lines at the top indicate receipts of live hogs in thousands, by the average in each month, for the fifteen years. The year is taken from September to August following, for correspondence with the crop year, as in previous charts.
Explanation.—No. 1 gives in the upper continuous line the average of top prices for mess pork in successive months; and in the lower line the average of bottom prices for the same months. The long, diagonal lines show the extreme of fluctuations in each month during the entire fifteen years. Thus the lowest price reached during the month of April in any year was $8.05, while the highest was $25.50. The lowest price in November of any year was $6.40, while the highest price in the same month was $15.50. No. 2 gives in the same way the average of top prices and bottom prices during the fifteen years for green hams; and by its diagonal lines, the extremes of fluctuation. No. 3 presents a corresponding showing of average top and bottom prices of live hogs, with extreme fluctuations. No. 4, at the top of the chart, gives the average receipts of live hogs in Chicago during the several months of the year, counted in thousands.
The supply of hogs.—The correspondence between the receipts of live hogs and the average market price in each month [pg 103] is worthy of study. Every farmer can see in what months of the year the market is fullest. It is also evident that the fluctuations in mess pork are much more extensive than in live hogs or fresh products. This is doubtless due to the possibility of speculation in a product which can be held for future market. Nevertheless, it is quite evident that the prices of mess pork have some direct connection with the supply available.
