"Beef packing was the leading industry of Chicago at that time, but no trustworthy statistics relating to the cattle traffic previous to 1851 have been preserved, and from 1851 until 1856 no account of the receipts of cattle were kept. This was probably due to the fact that a large number of those cattle that were brought to Chicago were held on the open prairies until sold to butchers to supply the requirements for local consumption. No accurate count of cattle disposed of in that way could well be obtained."
