This active cominercc between the West and South soon caused a rivalry in the East, that pushed for ward improvements by Statesor corporations to gain a share in the western trade. These improvements, as completed, gaveto the West a choice of markets, so that its farmers could elect whether to feed the slave who grows the cottonor the operatives who are engaged in its manufacture. But this rivalry did more. The comxctition for western products enhanced their price an stimulated their more extended cultivation. This required an enlargement of the markets and the extension of slavery became essential to "western prosperity. We have not reached the end of the alliance between the western farmer and southern planter.
