US Presidency

The length of the coast on the Atlantic from the northern limits of the United States around the capes of Florida to the Sabine, on the eastern boundary of Texas, is estimated to be 3,100 miles; so that the addition of seacoast, including Oregon, is very nearly two-thirds as great as all we possessed before, and, excluding Oregon, is an addition of 1,370 miles, being nearly equal to one-half of the extent of coast which we possessed before these acquisitions. We have now three great maritime fronts -on the Atlantic, the Gulf of Mexico, and the Pacific making in the whole an extent of seacoast exceeding 5,000 miles. This is the extent of the seacoast of the United States, not including bays, sounds, and small irregularities of the main shore and of the sea islands. If these be included, the length of the shore line of coast, as estimated by the Superintendent of the Coast Survey in his report, would be 33,063 miles. It would be difficult to calculate the value of these immense additions to our territorial possessions.
