This branch of trade ought not to be considered as a partial benefit. All the navigating States may, in different degrees, advantageously participate in it, and under circumstances of a greater extension of mercantile capital, would not be unlikely to do it. As a nursery of seamen, it now is, or when time shall have more nearly assimilated the principles of navigation in the several States, will become, a universal resource. To the establishment of a navy, it must be indispensable. To this great national object, a NAVY, union will contribute in various ways. Every institution will grow and flourish in proportion to the quantity and extent of the means concentred towards its formation and support. A navy of the United States, as it would embrace the resources of all, is an object far less remote than a navy of any single State or partial confederacy, which would only embrace the resources of a single part. It happens, indeed, that different portions of confederated America possess each some peculiar advantage for this essential establishment. The more southern States furnish in greater abundance certain kinds of naval stores--tar, pitch, and turpentine. Their wood for the construction of ships is also of a more solid and lasting texture. The difference in the duration of the ships of which the navy might be composed, if chiefly constructed of Southern wood, would be of signal importance, either in the view of naval strength or of national economy. Some of the Southern and of the Middle States yield a greater plenty of iron, and of better quality. Seamen must chiefly be drawn from the Northern hive. The necessity of naval protection to external or maritime commerce does not require a particular elucidation, no more than the conduciveness of that species of commerce to the prosperity of a navy.
