Second Centre. New York.
Radiating from New York are, 1. The railroad to Paterson, an important manufacturing town at the falls of the Passaic, 16 miles in length; 2. The New Brunswick railroad already mentioned, which serves as a route of communication with several important points, especially Newark, and for the transportation of provisions for the New York market from a portion of New Jersey; 3. The Harlæm railroad, almost exclusively for passengers; and 4. The Brooklyn and Jamaica railroad, on Long Island, 12 miles in length, and designed both for pleasure excursions, and for transporting articles of consumption to the markets of New York.[CH]
Third Centre. Philadelphia.
Around Philadelphia, in addition to the great works extending to Columbia, Amboy, and Baltimore, already mentioned, are 1. The Trenton railroad; 2. The Norristown and Germantown road, designed for passengers and for the accommodation of some manufacturing villages, such as Manayunk, 16 miles in length; and 3. That of West Chester, a branch of the Columbia railroad, 9 miles in length, designed for the supply of the markets of the city. There are also several railroads running through the city, of which the rails are laid on the level of the street, and on which horse-cars only are used.
Fourth Centre. Baltimore.
Beside the Baltimore and Ohio railroad with its Washington branch, Baltimore is also about to have a railroad through York, to the Susquehanna, opposite to Columbia, the length of which will be 73 miles. The object of this road is to contest with Philadelphia the commerce of the valley of the Susquehanna. The Pennsylvania canal with its various branches forms a canalisation of this river and its tributaries above Columbia. But below Columbia, there are several rapids and shoals which interrupt the navigation of the river, except for downward-bound boats in the highest stages of the water. The Philadelphia merchants, fearing that all the works executed at a great expense by Pennsylvania, would turn out much less advantageously for them than for the Baltimoreans, as these last have, indeed, openly boasted, opposed for a long time both the canalisation of the Susquehanna from Columbia to its mouth, and the permission to construct that section of a railroad from Baltimore to Columbia, which would lie within the limits of Pennsylvania. Their opposition has, however, been at last overcome, and charters have been granted authorising the construction of both works. The railroad company, to which Maryland has just made a loan of 1,000,000 dollars, is pushing on the railway with great activity.
Fifth Centre. Charleston.
Some short canals have been cut to facilitate the access to Charleston from the interior, but they are in a bad state, and are of little importance.
Sixth Centre. New Orleans.
Independently of the short railway of five miles from Lake Pontchartain to New Orleans, there are several other works, such as the Carrolton railroad, which is a little longer, and two short canals extending from the city to the lake. Some cuts have also been made between the lagoons and marshes of the lower Mississippi. These canals, dug in a wet and muddy soil, have presented serious difficulties in their construction; but they are of no interest in regard to extent or importance.
