IT is sometimes asked, with an air of seeming triumph, what inducements could the States have, if disunited, to make war upon each other? It would be a full answer to this question to say—precisely the same inducements which have, at different times, deluged in blood all the nations in the world. But unfortunately for us, the question admits of a more particular answer. There are causes of differences within our immediate contemplation, of the tendency of which, even under the restraints of a Fœderal Constitution, we have had sufficient experience, to enable us to form a judgment of what might be expected, if those restraints were removed.
