Among the other rumors, it is said Hooker is falling back toward Washington, but these are merely rumors.

The President is in a very feeble and nervous condition, and is really threatened with the loss of sight altogether. But he works on; and few or no visitors are admitted. He remains at his dwelling, and has not been in the executive office these ten days.

Col. Lay was merry again to-day. He ordered in another foreign substitute (in North Carolina).

Pins are so scarce and costly, that it is now a pretty general practice to stoop down and pick up any found in the street. The boarding-houses are breaking up, and rooms, furnished and unfurnished, are rented out to messes. One dollar and fifty cents for beef, leaves no margin for profit, even at $100 per month, which is charged for board, and most of the boarders cannot afford to pay that price. Therefore they take rooms, and buy their own scanty food. I am inclined to think provisions would not be deficient, to an alarming extent, if they were equally distributed. Wood is no scarcer than before the war, and yet $30 per load (less than a cord) is demanded for it, and obtained.

The other day Wilmington might have been taken, for the troops were sent to Beauregard. Their places have since been filled by a brigade from Longstreet. It is a monstrous undertaking to attempt to subjugate so vast a country as this, even with its disparity of population. We have superior facilities for concentration, while the invader must occupy, or penetrate the outer lines of the circumference. Our danger is from within, not from without. We are distressed more by the extortioners than by the enemy. Eternal infamy on the heads of speculators in articles of prime necessity! After the war, let them be known by the fortunes they have amassed from the sufferings of the patriots and heroes!—the widows and orphans!

This day is the anniversary of the secession of Virginia. The government at Washington did not believe the separation would last two years! Nor do they believe now, perhaps, that it will continue two years longer.

April 18th.—We have nothing more from the Peninsula, Suffolk, N. C., or South Carolina; but it is rumored that the enemy’s gun-boats (seven or eight) have passed down the Mississippi in spite of our batteries at Vicksburg, which sunk one of them. If this be true, it is bad news.

We have lovely weather now, and vegetation shows signs of the return of the vernal season. We shall soon have blossoms and roses in abundance, and table vegetables too, to dispel the fears of famine. But we shall also have the horrid sounds of devastating war; and many a cheerful dame and damsel to-day, must soon put on the weeds of mourning.

Gen. Jos. E. Johnston has assumed the command of the army of Tennessee. Gen. Howell Cobb is preparing for the defense of Florida. We do not hear a word from Lee or Jackson—but this is the ominous silence preceding their decisive action.

Bacon fell to-day from $2 to $1.50 per pound, and butter from $3.50 to $3.25; potatoes are $16 per bushel. And yet they say there is no scarcity in the country. Such supplies are hoarded and hidden to extort high prices from the destitute. An intelligent gentleman from North Carolina told me, to-day, that food was never more abundant in his State; nevertheless, the extortioners are demanding there very high prices.
