Another letter from Brig.-Gen. Meredith, Fortress Monroe, was received to-day, with a report of an agent on the condition of the prisoners at Fort Delaware. By this report it appears our men get meat three times a day—coffee, tea, molasses, chicken soup, fried mush, etc. But it is not stated how much they get. The agent says they confess themselves satisfied. Clothing, it would appear, is also issued them, and they have comfortable sleeping beds, etc. He says several of our surgeons propose taking the oath of allegiance, first resigning, provided they are permitted to visit their families. Gen. M. asks for a similar report of the rations, etc. served the Federal prisoners here, with an avowed purpose of retaliation, provided the accounts of their condition be true. I know not what response will be made; but our surgeon-general recommends an inspection and report. They are getting sweet potatoes now, and, generally they get bread and beef daily, when our Commissary-General Northrop has them. But sometimes they have little or no meat for a day or so at a time—and occasionally they have bread only once a day. It is difficult to feed them, and I hope they will be exchanged soon. But Northrop says our own soldiers must soon learn to do without meat; and but few of us have little prospect of getting enough to eat this winter. My family had a fine dinner to-day—the only one for months. As for clothes, we are as shabby as Italian lazzaronis—with no prospect whatever of replenished wardrobe, unless some European power will come and take us, as the French have done Mexico.

November 15th.—After a fine rain all night, it cleared away beautifully this morning, cool, but not unseasonable. There is no news of importance. The Governor of Georgia recommends, in his message, that the Legislature instruct their representatives in Congress to vote for a repeal of the law allowing substitutes, and also to put the enrolling officers in the ranks, leaving the States to send conscripts to the army. The Georgia Legislature have passed a resolution, unanimously, asking the Secretary of War to revoke the appointments of all impressing agents in that State, and appoint none but civilians and citizens. I hope the Secretary will act upon this hint. But will he?

The papers contain the following:

Arrived in Richmond.—Mrs. Todd, of Kentucky, the mother of Mrs. Lincoln, arrived in this city on the steamer Schultz, Thursday night, having come to City Point on a flag of truce boat. She goes South to visit her daughter, Mrs. Helm, widow of Surgeon-General Helm, who fell at Chickamauga. Mrs. Todd is about to take up her residence in the South, all her daughters being here, except the wife of Lincoln, who is in Washington, and Mrs. Kellogg, who is at present in Paris.”

“To the Poor.—C. Baumhard, 259 Main Street, between Seventh and Eighth, has received a large quantity of freshly-ground corn-meal, which he will sell to poor families at the following rates: one bushel, $16; half bushel, $8; one peck, $4; half peck, $2.”

November 16th.—Governor Brown, Georgia, writes the Secretary that he is opposed to impressments, and that the government should pay the market price—whatever that is. And the Rhett politicians of South Carolina are opposed to raising funds to pay with, by taxing land and negroes. So indicates the Mercury.

We have news to-day of the crossing of the Rapidan River by Meade’s army. A battle, immediately, seems inevitable.

November 17th.—A cold, dark day. No news. It was a mistake about the enemy crossing the Rapidan—only one brigade (cavalry) came over, and it was beaten back without delay.

Vice-President Stephens writes a long letter to the Secretary, opposing the routine policy of furloughs, and extension of furloughs; suggesting that in each district some one should have authority to grant them. He says many thousands have died by being hastened back to the army uncured of their wounds, etc.—preferring death to being advertised as deserters.

Captain Warner sent me a bag of sweet potatoes to-day, received from North Carolina. We had an excellent dinner.
