river, and by the Chicago or Green Bay routes to the Mississippi and the Gulf, her vast agricultural products in the peninsula would find new and augmented markets; while, with the ship canal to Lake Superior, her magnificent iron and copper mines on that immense inland sea, as well as those in Wisconsin, and the splendid pineries and fisheries of both States, would receive an immense development. Pennsylvania has no large available through route now from the Delaware and Susquehanna to the lakes, nor from Pittsburg. The proposed system would give her those routes, as well from the East as from the West. This would give to her coal and iron, her vast agricultural products, her immense manufactures, and all her industrial pursuits a new impulse, while her two great cities, Philadelphia and Pittsburg, would be greatly advanced in wealth and population. When we reflect that coal and iron have mainly contributed to make England what she is, and how superior, in this respect, are the natural advantages of Pennsylvania with her bituminous and anthracite coal and iron and fluxes in juxtaposition, with a _continent_ surrounding her to furnish a market, with her central location, fronting on the deep tidewater of the Delaware, and upon the lakes and the Ohio, with its two great confluents at Pittsburg, the Alleghany and Monongahela, we cannot fully realize the immense advantages which she would derive from these enlarged communications. But what of New York? With all her routes, as well as that of the Erie canal, enlarged as proposed, with her mighty system extending to the lakes and St. Lawrence, from Lake Champlain to Superior, south by the Delaware and Susquehanna, west by the Alleghany, Ohio, Missouri, and Mississippi, and her great city with an unrivalled location, what an imperial destiny lies before her, with the Union preserved? Oh! if she would only fully realize these great truths, and spurn from her embrace the wretched traitors who, while falsely professing peace, mean the degradation of the North and the dissolution of this Union, who can assign limits to her wealth and commerce?
