The steady march of the Republican party toward ascendancy was shown in the Thirty-sixth Congress, which met in December, 1859. There were now twenty-four Republican senators, and one hundred and nine representatives. Early in the first session of this Congress an interesting debate occurred in the Senate on a proposition to provide for the education of the colored children of the District of Columbia. Mr. Mason condemned the proposition, and said it was wise to prohibit the education of the colored race. Jefferson Davis declared that the Government was not made for them, and that "we have no right to tax our people to educate the barbarians of Africa." These and kindred utterances were very well calculated to aid the work of anti-slavery progress. John Brown's raid into Virginia kindled the ire of the slave-holders to a degree as yet unprecedented, and although his act found few defenders in the Northern States, the heroism with which he met his fate, the pithy correspondence between Gov. Wise and Mrs. Child, the language of Southern senators in dealing with the subject, and the efforts made to ferret out Brown's associates, all tended to strengthen the growing hostility to slavery and prepare the way for the final conflict. The designs of the slaveholders upon Cuba, which were avowed in this Congress, and their purpose to acquire it for the extension of slavery, by purchase if they could, but if not by war, served the same purpose. The growing demand for the revival of the African slave trade, as shown by the avowals of leading men in both houses of Congress, and their cold-blooded utterances on the subject, produced a profound impression on the country, and called forth the startling fact that the city of New York was then one of the greatest slave-trading marts in the world, and that from thirty to sixty thousand persons a year were taken from Africa to Cuba by vessels from that single port. Such facts as these, and that the laws of the Union for the suppression of the traffic were not only a dead letter but that the slave masters and their allies sullenly refused to take any steps whatever for the remedy of this organized inhumanity, were capital arguments for the Republicans, which they employed with telling effect. The refusal to admit Oregon as a State without a constitutional provision excluding people of color, the rejection of Kansas on her application with a Constitution fairly adopted by her people, and the great speech of Sumner on "The Barbarism of Slavery," which this last application called forth, all served their purpose in the growth of anti-slavery opinion. So did the attempt to divide California for the purpose of introducing slavery into the southern portion; the veto of an Act of the Territorial Legislature of Kansas abolishing slavery, and of a similar act in Nebraska; the acts of several Southern States permitting free colored persons to sell themselves as slaves
