The first market in the way of stock yards in Chicago was located on the north branch of the Chicago river. These yards were used chiefly for swine. In 1836, the first cattle yards were opened on a tract of land near twenty-ninth street and Cottage Grove avenue. A few pens had been erected here to accommodate the cattle trade. The first scales for weighing livestock ever used in that country were used in these yards.[11] In 1855, there were two regular stock yards in Chicago; one, called the Merrick Yard, is now known as the Sherman Yards, and the other was called the Bullshead Yard. A great many eastern people came to Chicago at this time to buy fat cattle to take back east. Most of the cattle they bought were driven over into Indiana to Michigan City, to be shipped on east. John L. Hancock was the only packer in Chicago at this time. Ice was not used, and packing was done during the cool seasons of the year. One element of the success of Chicago as a market was the fact that stock might be pastured without charge on the prairies near the city, while the owners awaited favorable market conditions in the eastern states. The cattle were herded on the open prairies just outside of the city, and the buyers of Chicago rode out each day and bought the cattle in such numbers as they needed. In 1865, the growth of the livestock traffic had increased so rapidly that the several railroad companies that centered in Chicago, together with the managers of the stock yards already existing, combined for the erection of the Union Stock Yards. These were opened for business on Christmas day, 1865.[12] "The meat industry of Chicago, from the purchase of the livestock to the shipment of the meat, in either the fresh or the cured condition, is carried on at the Union Stock Yards, which are located near the outskirts of the city. The yards cover exactly a square mile of ground. One-half of this area is covered with cattle pens, and the other half by huge establishments of the packing houses. The pens are surrounded by strong stockades, about shoulder high, and they are laid out in blocks with streets and alleys, in much the same fashion as an ordinary American town. The whole of this area, a half mile in width, and a mile in length, is paved with red brick; and here we see the first notable evidence of the effort to maintain the stock yards in a sanitary condition. "The brick paving makes it possible to thoroughly clean both pens and streets, and this is done at regular and frequent intervals."[13]
