When a farmer sells a steer, a lamb, or a hog, and the house-keeper buys a chop or roast, they enter a market which for the whole continent, and for all kinds of cattle and meats, is controlled by the combination of packers at Chicago known as "the Big Four."[32] This had its origin in the "evening" arrangement, made in 1873 by the railroads with preferred shippers, on the ostensible ground that these shippers could equalize or even the cattle traffic of the roads. They received $15 as "a commission" on every car-load of cattle shipped from the West to New York, no matter by whom shipped, whether they shipped it or had anything to do with it or not. The commission was later reduced to $10. They soon became large shippers of cattle; and with these margins in their favor "evening" was not difficult business.[33] By 1878 the dressed-beef business had become important. As the Evener Combine had concentrated the cattle trade at Chicago, the dressed-beef interest necessarily had its home at the same place. It is a curious fact that the Evener Combine ceased about the time the dressed-beef interest began its phenomenal career.[34] The committee appointed by the United States Senate to investigate the condition of the meat and cattle markets fixed upon St. Louis, Mo., and November 20, 1888, as the time and place of meeting, because the International Cattle Range Association and the Butchers' National Protective Association assembled at the same time and place. It was supposed that prominent members of these associations would avail themselves of the opportunity to appear before the committee. Some of them did testify frankly, but the presence of antagonistic influences, especially in the International Cattle Range Association, immediately became apparent, and industrious efforts were made to prevent the inquiries of the committee from affecting injuriously the dressed-beef interest at Chicago. The committee found that under the influence of the combination the price of cattle had gone down heavily. For instance: In January, 1884, the best grade of beef cattle sold at Chicago for $7.15 per hundred pounds, and in January, 1889, for $5.40; Northwestern range and Texas cattle sold in January, 1884, at $5.60, and in January, 1889, at $3.75; Texas and Indian cattle sold in 1884 at $4.75, the price declining to $2.50 in December, 1889. These are the highest Chicago prices for the months named.
