To-day a debate took place in the rebel Senate, on the bill to extend the operation of the sequestration act to all persons natives of or residents within any of the rebel States, and who had refused to submit to the constitution and laws of those States. A substitute proposed by the Committee of the Judiciary was adopted. It provided that the President of the rebel States should issue his proclamation, ordering all persons within the limits of those States who were loyal, and adhered to the United States Government, to leave the rebel States within forty days, on pain of forfeiture of property. Another of its provisions was the granting of immunity to all persons adhering to the Union who, within forty days, should take the oath of allegiance to the rebel States.
