Gen. Lee has been quite ill, but is now recovering.

April 21st.—Gen. Longstreet lost, it is said, two 32-pounder guns yesterday, with which he was firing on the enemy’s gun-boats. A force was landed and captured the battery.

Gen. Lee writes that his men have each, daily, but a quarter pound of meat and 16 ounces of flour. They have, besides, 1 pound of rice to every ten men, two or three times a week. He says this may keep them alive; but that at this season they should have more generous food. The scurvy and the typhoid fever are appearing among them. Longstreet and Hill, however, it is hoped will succeed in bringing off supplies of provision, etc.—such being the object of their demonstrations.

Gen. Wise has fallen back, being ordered by Gen. Elzey not to attempt the capture of Fort Magruder—a feat he could have accomplished.

April 22d.—The President is reported to be very ill to-day—dangerously ill—with inflammation of the throat, etc. While this is a source of grief to nearly all, it is the subject of secret joy to others. I am sure I have seen some officers of rank to-day, not fighting officers, who sincerely hope the President will not recover. He has his faults, but upon the whole is no doubt well qualified for the position he occupies. I trust he will recover.

The destruction of the Queen of the West, and of another of our steamers, is confirmed. Is not Pemberton and Blanchard responsible?

The loss of two guns and forty men the other day, on the Nansemond, is laid at the door of Major-Gen. French, a Northern man! Can it be Gen. Cooper (Northern) who procures the appointment of so many Northern generals in our army?

I cut the following from the Dispatch of yesterday:
