13. In contemplating the causes which may disturb our Union, it occurs as a matter of serious concern that any ground should have been furnished for characterizing parties by geographical discriminations,--Northern and Southern, Atlantic and Western,--whence designing men may endeavor to excite a belief that there is a real difference of local interests and views. One of the expedients of party to acquire influence within particular districts is to misrepresent the opinions and aims of other districts. You cannot shield yourselves too much against the jealousies and heartburnings which spring from these misrepresentations; they tend to render alien to each other those who ought to be bound together by fraternal affection. The inhabitants of our western country have lately had a useful lesson on this head: they have seen in the negotiation by the executive, and in the unanimous ratification by the Senate, of the treaty with Spain, and in the universal satisfaction at that event throughout the United States, a decisive proof how unfounded were the suspicions propagated among them of a policy in the general government and in the Atlantic States, unfriendly to their interests in regard to the Mississippi; they have been witnesses to the formation of two treaties, that with Great Britain and that with Spain, which secure to them everything they could desire, in respect to our foreign relations, towards confirming their prosperity. Will it not be their wisdom to rely for the preservation of these advantages on the Union by which they were procured? Will they not henceforth be deaf to those advisers, if such there are, who would sever them from their brethren, and connect them with aliens?
