We hear, from time to time, of the rebels being driven from most of the State. Then, anon, we hear of Longstreet controlling all East Tennessee except Knoxville and Chattanooga, and of an alarm in Memphis at an apprehended invasion of West Tennessee by a large rebel force. Evidently, Tennessee is only held by military force, and is therefore necessarily under military rule, and, so long as this is the case, the efforts to reorganize the state government with slavery restored are kept down. The presence of Federal authority, in the shape of an army, secures freedom of speech and of the press on the subject, which is unfavorable to the restoration of slavery. Large numbers of negroes have enlisted in the army, and these are all free by law, with their wives and children, and the number increases all the while that the State is held by the army. This also tends to weaken the system. A letter from a loyal Tennesseean, himself a slaveholder, of the date of Feb. 14th, says: "The slaveholders of Tennessee were always a small minority of the white population. Eight-tenths of those men were always rebels, are so in sympathy today. With a few noble exceptions, the unconditional Union men were and are non-slaveholders. The rebellion has ruined the present inhabitants of the State, every home has been darkened, mothers are broken-hearted, wives are widowed, and children are orphans. Wide-spread desolation and ruin are revealed to every eye. And now the question has come up for an answer, Who did all this, and for what was it done? The answer exposes the revolting deformity of slavery, and the sin and folly of slaveholders. At last, the long-oppressed and down-trodden 'poor white trash' are rousing for redress. There are unmistakable signs of a gathering storm, which will sweep the last vestige of slavery from the land." It is plainly enough to be seen that the last struggle of slavery against freedom will not be on the battlefield, at least in this war, but that the political and even the religious question will have to be met with the utmost energy in the subjugated States, after the military power of slavery is broken.—Independent.
