To-day the President sent it back indorsed as follows: “Maps of the country, with such additions as may from time to time be made, should be kept on hand in the Engineer Bureau, and furnished to officers in the field. Preparations of material for bridges, etc. will continue to be made as heretofore, and with such additional effort as circumstances require.

“I did not doubt the readiness of Gen. Beauregard to serve under any general who ranks him. The right of Gen. Lee to command would be derived from his superior rank.

“9th May, 1864.”

May 11th.—Bright and pleasant—breezy. This has been a day of excitement.

At midnight the Departmental Battalion were marched from the south side of the river back to the city, and rested the remainder of the night at Camp Lee. But at 9 a.m. they were marched hurriedly to Meadow Bridge. They came past our house. Custis and his brother Thomas ran in—remaining but a moment. Custis exclaimed: “Let me have some money, mother (I had to go to the office), or we will starve. The government don’t feed us, and we are almost famished. Cook something, and get Captain Warner to bring it in his buggy—do, if possible.” He got $20. They looked worn, and were black with dust, etc. My daughter said “they looked like negroes.”

The Secretary issued this morning a new edition of his handbills, calling the people “to arms.”

Mr. Mallory’s usual red face turned purple. He has not yet got out the iron-clad Richmond, etc., which might have sunk Gen. Butler’s transports.

Lieut.-Col. Lay was exhibiting a map of our defenses, and predicting something,—whether good or evil, I did not stay to learn. But I thought such maps ought not to be shown in the public hall of the department.

The armory was open to-day, and all who desired them were furnished with arms.
