In the meantime the executive department--no other plan having been proposed by Congress--continued its efforts to perfect, as far as was practicable, the restoration of the proper relations between the citizens of the respective States, the States, and the Federal Government, extending from time to time, as the public interests seemed to require, the judicial, revenue, and postal systems of the country. With the advice and consent of the Senate, the necessary officers were appointed and appropriations made by Congress for the payment of their salaries. The proposition to amend the Federal Constitution, so as to prevent the existence of slavery within the United States or any place subject to their jurisdiction, was ratified by the requisite number of States, and on the 18th day of December, 1865, it was officially declared to have become valid as a part of the Constitution of the United States. All of the States in which the insurrection had existed promptly amended their constitutions so as to make them conform to the great change thus effected in the organic law of the land; declared null and void all ordinances and laws of secession; repudiated all pretended debts and obligations created for the revolutionary purposes of the insurrection, and proceeded in good faith to the enactment of measures for the protection and amelioration of the condition of the colored race. Congress, however, yet hesitated to admit any of these States to representation, and it was not until toward the close of the eighth month of the session that an exception was made in favor of Tennessee by the admission of her Senators and Representatives.
