Gen. Lee writes that the railroad brings him but 1000 bushels of corn per day; not enough to bring up his exhausted cavalry and artillery horses; and he suggests that passenger cars be occasionally left behind for the purpose of supplying the army—an indispensable measure.

Gen. Lee also writes that he has 1700 unarmed men in his army; in two weeks there will be 5000, and in a month 10,000. He suggests that the troops for local defense here, and even the militia, be disarmed, to supply his men. This indicates that Lee is to have an immense army, and that Richmond is to be defended. But the Central and Fredericksburg Railroads must be repaired immediately, and at any expense to the government, or else all will fail!

August 11th.—After all the applications of the railroad companies when Gen. Lee was in Pennsylvania, and the enemy had withdrawn from this side of the Potomac, it appears that the fine iron on the road from Fredericksburg to Aquia Creek was not removed! Mr. Seddon’s subordinates must answer for this. The iron was wanted more than anything else but men. The want of men cannot be alleged for not securing it, because the railroad companies would have procured negroes enough for its removal.

Well, the first of August has passed, and the grand scheme of the War Office at Washington of a general servile insurrection did not take place. On the contrary, a large army of slaves might be organized to fight for their masters.

To-day, it must be confessed, I saw some of the booty (if, indeed, it was not fairly bought) of the recent invasion of the North. A number of boxes of fine stationery, brought from Carlisle, Chambersburg, etc., were opened at the War Department.

There is a controversy between the Secretary of War, Assistant Secretary, and Attorney-General on one side, and the Commissary-General, Col. L. B. Northrop, on the other. It appears that one of the assistant commissaries exchanged sugar for flour and rice in Alabama with a merchant or speculator, and then, after the lapse of a month or so, impressed the sugar. The party got the Attorney-General’s opinion in his behalf, which was approved by the Assistant Secretary of War, and the Secretary issued an order for the release of the sugar. In response to this, Col. N. rebuts the arguments of the whole three (lawyers) by saying it is not good sense to exempt anything, under any circumstances, from impressment, when needed to carry on the war; and that the way to success is to do justice to the whole country—and not to please the people. A palpable hit at the politicians. He says if the Secretary insists on the sugar being released, it will be done against his (N.’s) judgment.

August 12th.—Letters from Georgia to-day assure the government that the grain crops of that State will afford a surplus sufficient for the army, cavalry and all, for 12 months.

Also one from P. Clayton, late Assistant Secretary of the Treasury, censuring the commissary agents in Georgia, who are sent thither from other States, who insult the farmers and encourage speculation.

Mr. Memminger is shipping gold from Wilmington, $20,000 by each steamer, to Bermuda and Nassau. Why is this? Cotton is quite as good as gold, and there are thousands of millions worth of that in the country, which Mr. Memminger might buy, certainly might have bought for Confederate notes, but, in his peculiar wisdom, he would not. And now, the great financier is shipping gold out of the country, thinking, perhaps, it may arrest the depreciation of paper money!

Col. Northrop, Commissary-General, is still urging a diminution of rations, and as our soldiers taken by the enemy fare badly in the North, and as the enemy make a point of destroying all the crops they can when they invade us, and even destroy our agricultural implements and teams, he proposes, in retaliation, to stop meat rations altogether to prisoners in our hands, and give them instead oat gruel, corn-meal gruel, and pea soup, soft hominy, and bread. This the Secretary will not agree to, because the law says they shall have the same as our troops.
