They charged as a further means of firing the Southern heart, that this moneyed power, born of Protection, "works upon the passion of the States it has been able to delude by computations of their physical strength and their naval superiority; and by boasting of an ability to use the weakening circumstance of negro slavery to coerce the defrauded and discontented States into submission." And they declared as fundamental truths upon which they rested that "The Federal is not a National Government; it is a league between nations. By this league, a limited power only over persons and property was given to the representatives of the united nations. This power cannot be further extended, under the pretext of national good, because the league does not create a national government." It was the passage of the Tariff of 1824 that gave these crafty Free Traders their first great success in spreading their doctrine of Free Trade by coupling it with questions of slave labor, States Rights, and nullification, as laid down in the Kentucky and Virginia resolutions. These arguments created great excitement throughout the South --especially in South Carolina and Georgia--which was still further increased by the passage of the Tariff of 1828, since declared by eminent authority to have been "the highest and most protective ever adopted in this country." [Mr. Greeley, in his "History of the American Conflict," 1864.] Prior to the passage of this Tariff Act, excited assemblages met in some of the Southern States, and protested against it as an outrage upon their rights--arraying the South in seditious and treasonable attitude against not only the North but the Union, with threats of Secession. At one of these meetings in South Carolina, in 1827, one of their leaders --[Dr. Thomas Cooper, President of South Carolina College.]--declared that "a drilled and managed majority" in the House of Representatives had determined "at all hazards to support the claims of the Northern manufacturers, and to offer up the planting interest on the altar of monopoly." He denounced the American system of Protection exemplified in that Tariff measure as "a system by which the earnings of the South are to be transferred to the North--by which the many are to be sacrificed to the few--under which powers are usurped that were never conceded--by which inequality of rights, inequality of burthens, inequality of protection, unequal laws, and unequal taxes are to be enacted and rendered permanent--that the planter and the farmer under this system are to be considered as inferior beings to the spinner, the bleacher, and the dyer--that we of the South hold our plantations under this system, as the serfs and operatives of the North, subject to the orders and laboring for the benefit of the master-minds of Massachusetts, the lords of the spinning jenny and peers of the power-loom, who have a right to tax our earnings for their emolument,
