The poverty and disasters of early days seemed only to nerve the city to renewed determination and prepare her to meet with stoic faith the appalling calamities of later years. In this résumé it is only possible to catalogue the misfortunes that visited her. Floods swept away her shipping, fire destroyed her accumulating industries, raging epidemics reduced her population--cholera alone in 1854 causing 1424 deaths--and financial panic again and again returned to manacle activities. Many times in Chicago's history citizens could well exclaim: "One woe upon another's heels doth tread, so fast they follow!" Unconquerable in the presence of these recurrent visitations, the city pressed forward to her place as the metropolis of the Mississippi empire. At an early day "prairie schooners," pioneers of the great freight trains to come, laden with grain from the fertile areas round about began to line the prairie roads leading to Chicago. In 1839, two years after the city was begun, a crude grain elevator was constructed. The farmers, too poor to furnish sacks, brought their grain in sheets, blankets, and pieces of canvas. It was hoisted by hand with block and tackle to the elevator, and in the year mentioned 2900 bushels of wheat, consigned to Black Rock, New York, were dumped loose into the hold of the brig _Osceola_. From this primitive beginning has grown a mighty volume of trade in grain. In 1900 the wheat, corn, oats, rye, and barley shipped from Chicago amounted to 232,267,109 bushels, while the receipts aggregated 307,723,135 bushels. It was not until 1843 that the Common Council came to the conclusion that the place was sufficiently advanced as a city to warrant the enactment of an ordinance declaring that hogs should no longer be permitted to run at large in the streets. In 1900, far from being unwelcome, over 8,000,000 hogs, safely penned in cars, arrived in the city and were sent to the slaughter. In writing of Chicago it is customary to deal in superlatives, and this is necessary in the nature of things. Its Union Stock Yards cover 400 acres, nearly twice the area of the original town. Twenty miles of streets thread this meat-packing colony, which pays wages amounting to nearly $9,000,000 a year. In 1900 there were shipped to Chicago 277,205 carloads of hogs, cattle, sheep, etc. Its trade in grain leads every city in the world, while its general mercantile traffic is surpassed by few.
