whole line of the Boston and Albany road was completed, which thus became the first important through route in America. The construction of railroads in the United States was from the first carried on without a system. Railroads in an early day were purely local affairs. Each locality operated its own road in its own interest and without any supervision from the State which had granted its charter. Acts of incorporation or charters were granted as a matter of course. Railroads were looked upon as the natural feeders of canals, and their future importance was foreseen by very few men. The early roads were a heavy burden on the capital of the country. A number of small roads were built that proved unprofitable and had to be abandoned. After the financial panic of 1837 there was, except in New England, a very perceptible stagnation in railroad enterprise, which lasted until the discovery of gold in California, in 1848. The average number of miles of road constructed per annum during the ten years preceding 1848 was 380, while it was nearly 1,800 per annum during the seven years following. It may be said that with the discovery of gold in the West ends the first or formative period of railroad construction. From the first opening of the Baltimore and Ohio to the beginning of the year 1848, a period of eighteen years, there were constructed in the United States 5,205 miles of railroad, or an average of 289 miles per annum. The discovery of gold on the Pacific gave a new impetus to railroad construction throughout the country. Railroads now ceased to be local works and became interstate or national thoroughfares. Extensive new lines were built and through routes were formed by the coalition of local roads. It was during this period that railroad companies first became conscious of the importance of their mission and that they commenced to compete with river and canal carriers. In 1848 a through route was completed between Cincinnati and Lake Erie. A more direct line, the Cleveland, Columbus and Cincinnati road, was opened in 1851. During the same year the Erie Railroad reached Lake Erie and connected the lake with the Hudson, and a year later Chicago received railroad connection with the East by the completion of the Michigan Central and Michigan Southern. In 1854 the Chicago and Rock Island reached the Mississippi River, and in 1855 the Chicago and Galena was opened. One year later the Illinois Central reached the Mississippi at Cairo, and the Chicago, Burlington and Quincy Railroad was opened to Quincy. The Ohio and Mississippi, between Cincinnati and St. Louis, was completed at about the same time. The Pittsburgh, Fort Wayne and Chicago, an extension of the Pennsylvania road, was completed to Chicago in 1858. At the beginning of 1859 the Hannibal and St. Joseph Railroad reached the Missouri River, and eight years later the Cedar Rapids and Missouri was completed to the Missouri at Council Bluffs.
