President Lincoln’s message to the Congress of the United States, republished in our papers, produces no marked effect. His adherence to a purpose of emancipation of the slaves, and his employment of them in his armies, will suffice for an indefinite prolongation of the war, and perhaps result in the employment of hundreds of thousands of slaves in our armies. The intimation, however, that all applications for “pardon,” etc. have been and are still favorably entertained, will certainly cause many of our croakers who fall into the lines of the United States forces to submit. Others, though so disposed, have not an opportunity to signify their submission. But everything depends upon events in the field.

December 12th.—Clear and cold. Ice half an inch thick.

Gen. Longstreet is again in the old lines on this side of the river. The reconnoissance, however, is said to have been successful. Only a few were killed and wounded on either side.

And Grant’s column was turned back from Meherrin bridge. Results of the movement unimportant, and the supposition is that both armies will now go into winter quarters, after a taste of this rigorous weather.

It is rumored and believed (though I have seen no dispatch to that effect) that Sherman has beaten and out-manœuvred our generals, and got into communication with the Federal fleet.

I read President Lincoln’s message carefully last night. By its commissions and omissions on Mexican affairs, I think he means to menace Louis Napoleon, who may speak out January 1st, 1865. Lincoln says:

“Mexico continues to be a theater of civil war. While our political relations with that country have undergone no change, we have at the same time strictly maintained neutrality between the belligerents.”

And his reference to England is so equivocal, and his grouping of the Central and South American Republics so prominent, and the boastful allusion to the “inexhaustible” resources of the United States, may be considered as a premeditated threat to Great Britain.

A “confidential” letter came in to-day from Mr. Benjamin to the Secretary of War.

Dr. Powell has sent us a dozen ruta baga turnips, and a couple of quarts of excellent persimmons, which the family enjoys most thankfully.
