Hon. D. M. Lewis, Sparta, Ga., writes that he will cut his wheat on the 28th (to-morrow), and both for quality and quantity he never saw it equaled. They have new flour in Alabama; and everywhere South the crops are unprecedented in amount.

To-morrow is election day. For Congress, Col. Wickham, who voted against secession, opposes Mr. Lyons. But he has fought since!

We have a letter from Gen. Jos. E. Johnston, dated at Calhoun, Miss., 16th inst. He says the enemy on the railroad at Clinton numbered 25,000. We got our baggage out of Jackson before it was abandoned. Pemberton marched to Edward’s Station with 17,000 men. Gen. Johnston himself had 7500, and some 15,000 more were on the way to him. We had 3000 at Port Hudson—being over 40,000 which he meant to concentrate immediately. I think Vicksburg ought to be safe.

Our government has been notified that, if we execute the two officers (selected by lot) in retaliation for the execution of two of our officers in Kentucky, two men will be shot or hung by the enemy. Thus the war will be still more terrible!

Vallandigham has been sent to Shellbyville, within our lines. I think our people ought to give him a friendly greeting.

May 28th.—There is some animation at the polls, this being election day. It is said Mr. Wickham, who for a long time, in the Convention, voted against the secession of Virginia, is leading Mr. Lyons, an original secessionist, and will probably beat him. And Flournoy, an old Whig politician, will probably be elected governor.

A dispatch from Gen. Johnston, dated yesterday, says in every fight, so far, around Vicksburg, our forces have been successful, and that our soldiers are in fine spirits.

Papers from the North have, in great headings, the word victory, and announce that the Stars and Stripes are floating over the City of Vicksburg! They likewise said their flag was floating over the Capitol in this city. If Vicksburg falls, it will be a sad day for us; if it does not fall, it will be a sad day for the war party of the United States. It may be decisive, one way or the other. If we beat them, we may have peace. If they beat us—although the war will not and cannot terminate—it may degenerate into a guerrilla warfare, relentless and terrible!

May 29th.—A dispatch from Gen. Johnston, dated 27th inst., says fighting at Vicksburg had been in progress ever since the 19th instant, and that our troops have been invariably successful in repulsing the assaults. Other dispatches say the unburied dead of the enemy, lying in heaps near our fortifications, have produced such an intolerable stench that our men are burning barrels of tar without their works.

But still all is indefinite. Yet, from the persistent assaults of the enemy it may be inferred that Grant is inspired with the conviction that it is necessary for him to capture Vicksburg immediately, and before Johnston collects an army in his rear. A few days may produce a decisive result.
