But Missouri must be admitted as a slave State, for two strong reasons. First, that the planters might perpetuate their predominant influence by adding to the slave representation,--the power of which is always concentrated against the interests of the free States. Second, that a new market might be opened for their surplus slaves. It is lamentable to think that two votes in favor of Missouri slavery, were given by Massachusetts men; and that those two votes would have turned the scale. The planters loudly threatened to dissolve the Union, if slavery were not extended beyond the Mississippi. If the Union cannot be preserved without crime, it is an eternal truth that nothing good can be preserved _by_ crime. The immense territories of Louisiana, Arkansas, and Florida, are very likely to be formed into slave States; and every new vote on this side, places the free States more and more at the mercy of the South, and gives a renewed and apparently interminable lease to the duration of slavery. The purchase or the conquest of the Texas, is a favorite scheme with Southerners, because it would occasion such an inexhaustible demand for slaves. A gentleman in the Virginia convention thought the acquisition of the Texas so certain, that he made calculations upon the increased value of negroes. We have reason to thank God that the jealousy of the Mexican government places a barrier in that direction. The existence of slavery among us prevents the recognition of Haytian independence. That republic is fast increasing in wealth, intelligence and refinement.--Her commerce is valuable to us and might become much more so. But our Northern representatives have never even made an effort to have her independence acknowledged, because a colored ambassador would be so disagreeable to our prejudices. Few are aware of the extent of _sectional_ dislike in this country; and I would not speak of it, if I thought it possible to add to it. The late John Taylor, a man of great natural talent, wrote a book on the agriculture of Virginia, in which he acknowledges impoverishment, but attributes it all to the mismanagement of _overseers_. In this work, Mr. Taylor has embodied more of the genuine spirit, the ethics and politics, of planters, than any other man; excepting perhaps, John Randolph in his speeches. He treats merchants, capitalists, bankers, and all other people not planters, as so many robbers, who live by plundering the slave-owner, apparently forgetting by what plunder they themselves live. Mr. Jefferson and other eminent men from the South, have occasionally betrayed the same strong prejudices; but they were more guarded, lest the democracy of the North should be undeceived, and their votes lost. Mr. Taylor's book is in high repute in the Southern States, and its sentiments widely echoed; but it is little known here.
