These provisions, which have necessarily been consumed by others, would have added to the time we have already been at this post subsistence for the following number of days, respectively:

Pork-Sixteen and twenty-seven-ninetieth days.

Flour and hard bread-Forty and sixty-five-ninetieth days.

Beans-Eleven and one-ninth days.

Coffee-Nineteen and one-third days.

Sugar-Fifty-seven and one-third days.

Or, with what is now on hand, at least thirty-five days of comfortable subsistence for the command, including the laundresses, who were sent away about two months ago.

I have the honor to be, very respectfully,

NORMAN J. HALL,

Second Lieutenant, First Artillery, A. A. C. S.

FORT SUMTER, S. C., April 2, 1861.

General JOS. G. TOTTEN,

Chief Engineer U. S. Army, Washington, D. C.:

GENERAL: Owing to a dense fog which has prevailed since last evening nothing can be seen beyond a few yards from the fort. There are no indications to believe that there is any movement on foot, or that the state of partial inactivity last reported has been at all changed. The necessary permit from the governor for the discharged men to land at Fort Johnson did not arrive in season yesterday, consequently they remained, and will probably leave at 12 m. to-day.

I have the honor to be, very respectfully, your obedient servant,

J. G. FOSTER,

Captain, Engineers.
