John N. Holloway, History of Kansas — Chapter 4 (1868)
“ It is argued that by extending slavery west, the condition of both master and slave would be improved; but it is replied that by extension the growth of slavery is only accelerated, that it is a curse, and the more it is extended, the more country it afflicts. It was asserted that these conditions would be degrading and humiliating to the sovereign State of Missouri; but it is retorted that other States have complied with them and not felt in the least degraded, but were proud of their positions among the sister States, and were unequaled in prosperity and promise. ”
