Mr. RICE, of Kentucky in his speech in the Convention that formed the Constitution of that state, in 1790, says: "He [the slave] is a rational creature, reduced by the power of legislation to the _state of a brute_, and thereby deprived of every privilege of humanity.... The brute may steal or rob, to supply his hunger; but the slave, though in the most starving condition, _dare not do either, on penalty of death, or some severe punishment_." Rev. HORACE MOULTON, a minister of the Methodist Episcopal Church, in Marlborough, Mass. who lived some years in Georgia, says: "The southern horses and dogs have enough to eat, and good care is taken of them; but southern negroes--who can describe their misery and their wretchedness, their nakedness and their cruel scourgings! None but God. Should we _whip our horses_ as they whip their slaves, even for small offences, we should expose ourselves to the penalty of the law." Rev. PHINEAS SMITH, Centerville, Allegany county, New York, who has resided four years in the midst of southern slavery-- "Avarice and cruelty are twin sisters; and I do not hesitate to declare before the world, as my deliberate opinion, that there is _less compassion_ for working slaves at the south, than for working oxen at the north." STEVEN SEWALL, Esq. Winthrop, Maine, a member of the Congregational Church, and late agent of the Winthrop Manufacturing Company, who resided five years in Alabama, says-- "I do not think that brutes, not even horses, are treated with _so much cruelty_ as American slaves." If the preceding considerations are insufficient to remove incredulity respecting the cruelties suffered by slaves, and if northern objectors still say, 'We might believe such things of savages, but that civilized men, and republicans, in this Christian country, can openly and by system perpetrate such enormities, is impossible';--to such we reply, that this incredulity of the people of the free states, is not only discreditable to their intelligence, but to their consistency.
