I believe in my work on the "War Powers of the Government," etc., I was the first writer who has succeeded in placing the power of the Government to arrest for political offences, and to suspend the writ of _habeas corpus_, on its true foundation.

ANNA ELLA CARROLL. * * * * * In October, 1862, Miss Carroll wrote the following letter to the Secretary of War, through the hands of John Tucker, Assistant Secretary, on the reduction of Vicksburg: "As I understand an expedition is about to go down the river for the purpose of reducing Vicksburg, I have prepared the enclosed map in order to demonstrate more clearly the obstacles to be encountered in the contemplated assault. In the first place, it is impossible to take Vicksburg in front without too great a loss of life and material, for the reason that the river is only about half a mile wide, and our forces would be in point-blank range of their guns, not only from their water batteries, which line the shore, but from the batteries that crown the hills, while the enemy would be protected by the elevation from the range of our fire. By examining the map I enclose you will at once perceive why a place of so little apparent strength has been enabled to resist the combined fleets of the upper and lower Mississippi. The most economical plan for the reduction of Vicksburg now is to push a column from Memphis to Corinth, down the Mississippi Central railroad to Jackson, the capital of the State of Mississippi. _The occupation of Jackson and the command of the railroad to New Orleans would compel the immediate evacuation of Vicksburg_, as well as the retreat of the entire rebel army east of that line, and by another movement of our army from Jackson, Mississippi, or from Corinth to Meridian, in the State of Mississippi, on the Ohio and Mobile railroad, especially if aided by a movement of our gunboats on Mobile, the Confederate forces, with all the disloyal men and their slaves, would be compelled to fly east of the Tombigbee. Mobile being then in our possession, with 100,000 men at Meridian we would redeem the entire country from Memphis to the Tombigbee river. Of course I would have the
