But there was a larger sphere for this young man, just entering manhood, than a stall in the market house. In common with multitudes of young men and men in middle age he was turning his thoughts towards the boundless West. Ohio was the bourne for emigrants at that period. Thousands of New Englanders were selecting their homes in the Western Reserve. At Ashtabula the young man from Quincy market began the business of supplying Boston and New York with beef and pork, making his shipments via the Erie Canal. But there was a farther West, and in the Winter of 1833-4 he proceeded to Chicago, then a village of three hundred inhabitants, and began to supply them, and the company of soldiers garrisoning Fort Dearborn, with fresh beef; hanging up his slaughtered cattle upon a tree standing on the site now occupied by the Court House. This glance at the condition of society and the mechanic arts during the boyhood of Sylvester Marsh, and this look at the struggling village of Chicago when he was in manhood's prime, enables us to comprehend in some slight degree the mighty trend of events during the life time of a single individual; an advancement unparalleled through all the ages. For eighteen years, the business begun under the spreading oak upon what is now Court House square, in Chicago, was successfully conducted,--each year assuming larger proportions. He was one of the founders of Chicago, doing his full share in the promotion of every public enterprise. The prominent business men with whom he associated were John H. Kuisie, Baptiste Bounier, Deacon John Wright, Gurdon S. Hubbard, William H. Brown, Dr. Kimberly, Henry Graves, the proprietor of the first Hotel, the Mansion house, the first framed two-story building erected, Francis Sherman, who arrived in Chicago the same year and became subsequent builder of the Sherman House. Mr. Marsh was the originator of meat packing in Chicago, and invented many of the appliances used in the process--especially the employment of steam. In common with most of the business men of the country, he suffered loss from the re-action of the speculative fever which swept over the country during the third decade of the century; but the man whose boyhood had been passed on the Campton hills was never cast down by commercial disaster. His entire accumulations were swept away, leaving a legacy of liability; but with undaunted bravery he began once more, and by untiring energy not only paid the last dollar of liability, but accumulated a substantial fortune--engaging in the grain business. His active mind was ever alert to invent some method for the saving of human muscle by the employment of the forces of nature. He invented the dried-meal process, and "Marsh's Caloric Dried Meal" is still an article of commerce.
