We have no war news to-day.

March 28th.—April-like day, but no rain; clouds, and sunshine, and warm.

About 2 p.m. the Secretary received a dispatch stating that the enemy had appeared in force opposite Fredericksburg, and attempted, without success, to cross. A copy of this was immediately sent to Gen. Lee.

It is said that Gen. Longstreet is marching with expedition down the Valley of the Shenandoah, to flank Meade or Grant. I doubt it. But the campaign will commence as soon as the weather will permit.

A letter from G. B. Lamar, Savannah, Ga., informs the Secretary that he (L.) has command of five steamers, and that he can easily make arrangements with the (Federal) commandant of Fort Pulaski to permit them to pass and repass. His proposition to the government is to bring in munitions of war, etc., and take out cotton, charging one-half for freight. Mr. Memminger having seen this, advises the Secretary to require the delivery of a cargo before supplying any cotton. Mr. M. has a sort of jealousy of Mr. Lamar.

March 29th.—A furious gale, eastern, and rain.

No news, except the appearance of a few gun-boats down the river; which no one regards as an important matter.

Great crowds are funding their Treasury notes to-day; but prices of provisions are not diminished. White beans, such as I paid $60 a bushel for early in this month, are now held at $75. What shall we do to subsist until the next harvest?

March 30th.—It rained all night, the wind blowing a gale from the east. This morning the wind was from the west, blowing moderately; and although cloudy, no rain.

The enemy’s gun-boats down the river shelled the shore where it was suspected we had troops in ambush; and when some of their barges approached the shore, it was ascertained they were not mistaken, for a volley from our men (signal corps) killed and wounded half the crew. The remainder put back to the gun-boats.
