The opening of the Ohio canal was the first grand starting point in the commercial history of Cleveland. It brought into connection with the lake highway to market a rich country rapidly filling up with industrious settlers, and the products of dairies, grain farms, and grazing lands were brought in great quantity to Cleveland, where they were exchanged for New York State salt, lake fish, and eastern merchandise. Two years after the opening of the canal, which was completed in 1832, the receipts amounted to over half a million bushels of wheat, a hundred thousand barrels of flour, a million pounds of butter and nearly seventy thousand pounds of cheese, with other articles in proportion. Business went on increasing with great rapidity; every one was getting rich, in pocket or on paper, and Cleveland was racing with its then rival, but now a part of itself, Ohio City, for the distinction of being the great commercial centre of the West. At that moment, in the year 1837, the great crash came and business of all kinds was paralyzed. Cleveland was one of the first places in the West to recover. Its basis was good, and as the interior of Ohio became more peopled the trade of the canal increased and, of course, Cleveland was so much the more benefited. The opening of the Pennsylvania and Ohio canal, in 1841, opened communication with Pittsburgh and added a trade in iron, nails, and glass to the other branches of business. In 1844 the commerce of Cleveland by lake had reached an aggregate of twenty millions for the year.
