Practically all of the live stock figures since 1903 have been compiled from the Chicago Drovers’ Journal Year Books. Mr. Chas. A. S. McCracken has compiled the price figures from actual transactions day by day in the stockyards for the past thirty years, and is still with the Drovers’ Journal. The original source for live stock receipts is the stock yards companies, but we have used the reports of the Drovers’ Journal. For the years 1903, 1904 and 1905, for receipts at six markets, we have used figures furnished by Mr. M. F. Horine, statistician for the Chicago Union Stock Yards. These figures seem to be comparable with the figures for the later years, except in the case of cattle, where there is evidently some confusion in the counting of calves. The cattle receipts at six markets, as published by 1903, 1904 and 1905 reports, are about 8 per cent too large to be truly comparable with the later years. * * * * * RETAIL PRICES. Retail price figures are taken from the publications of the Bureau of Labor Statistics. Concerning the significance of these figures, the following statement of Royal Meeker, Commissioner of Labor Statistics, is of value: “We secure retail prices of 44 articles of food from 50 cities on the 15th of each month. The stores selected are those patronized by wage-earners. The goods carried are standard grades and brands. The Bureau requests that these grades and brands be uniform thruout the year, as nearly as possible. Some of these stores are ‘cash-and-carry,’ and some of them deliver, depending on the locality in which they are situated. The Bureau makes every effort to have each city represented by a sufficient number of stores so the prices published for that city will represent the average prices charged to the wage-earner. Of course, the chances are that there will be differences, as we do not carry either the high-class stores or the cut-rate stores.” CHICAGO HEAVY HOG PRICES.
