The weather is dark and threatening. Again the rumor is circulated that ex-Gov. Letcher is to be Secretary of War. I don’t believe that.

Major Tachman claims $5000 in gold and $1600 paper, because after raising two regiments in 1861 he was not made a brigadier-general. He says he expended that much money. I thought this Polish adventurer would give the government trouble.

Custis commenced his school to-night, with three scholars,—small beginnings, etc.

January 5th.—Bright, pleasant day. I saw a letter from Gen. Elzey to-day, stating that his command will probably soon be called out from the city on important service. What can this mean? And our iron-clads are to go below the obstructions if they can get out.

Yesterday Mr. Good offered a resolution declaring the unalterable purpose of Congress to prosecute the war until independence is attained. What significance is in this? Why declare such a purpose at this day?

Mr. Benjamin, Gen. Myers, Col. Preston, and Mr. Seddon are to partake of a feast on Thursday. A feast in time of famine!

January 6th.—Yesterday Mr. Moffitt, Lieut.-Col. Ruffin’s agent (commissary), was in the market buying beef for Gen. Lee’s army! And this same Moffitt was in September selling beef to the same butchers (as they say) at from 40 to 50 cts. gross, the impressing price in the country being 20 cts.

On the 2d inst. Gen. Lee wrote the President that he had just heard of two droves of cattle from the West, destined for his army, being ordered to Richmond. [He does not say by whom, or for what purpose. He knew not.] He says he has but one day’s meat rations, and he fears he will not be able to retain the army in the field. The President sent a copy of this to the Commissary-General, with a few mild remarks, suggesting that he shall get such orders from the Secretary of War as are necessary in such an emergency. In response to this the Commissary-General makes a chronological list of his letters to Gen. Lee and others, pretending that if certain things were not done, the army, some day, would come to want, and taking great credit for his foresight, etc. This table of contents he ran first to the department with, but not finding the Secretary, he carried it to the President, who returned it without comment to Col. N. yesterday, and to-day the Secretary got it, not having seen it before. Well, if Col. N. had contracted with Capt. Montgomery for the 1,000,000 pounds of salt beef, it would have been delivered ere this. But the Secretary never saw Capt. M.’s offer at all!

January 7th.—Gen. J. E. Johnston dispatches from the West that the meat is so indifferent, the soldiers must have an additional quantity of rice.

Beef sells to-day at $1.25 per pound by the quarter. And yet an Englishman at the best hotel yesterday remarked that he never lived so cheaply in any country, his board being only three shillings (in specie) per diem, or about $20 Confederate States notes.
