Fire from the enemy's batteries was resumed at daylight, and from Fort Sumter at 7 A. M. At about 8 the officers' quarters in Sumter took fire from a shell, and the work at the guns was necessarily somewhat slackened, as nearly all the men were taken away to extinguish the flames. Shells from Moultrie and Morris' Island fell now faster than ever. Dense volumes of smoke still poured out of the barracks at 9, when the men were again sent to the guns. At 10 o'clock the halliards on the  flag-staff were cut by a shell, and the flag ran down a little and stuck, so that it appeared to be displayed at half-mast. Several ships, one a large steamer, were in the offing at 10.30, and shots were fired at them from Morris' Island and Fort Moultrie. About 11 o'clock the fire in the barracks again burst forth fiercely. Three piles of hand-grenades and shells, placed ready for use, became heated by it and exploded at intervals. The day was oppressively warm, and the heat of the fire added, made the atmos phere of the fort almost insufferable. At 12 the whole roof of the barracks was in flames, and soon after men were set to work to take the powder out of the magazine, lest the heat should reach and explode it there. Ninety barrels were rolled out and the doors closed. The fire of Fort Sumter was now almost entirely relinquished, though from the other forts it was rather increased. Cartridges were nearly all gone, and owing to the flying sparks no more could be made. Smoke from the fire was blown into the fort so thickly that the men could not see one another. As the fire in the barracks spread from the officers' to the men's quarters, it became necessary to throw overboard the powder that had been taken from the magazines. All was thrown over but three barrels, which were wrapped around with wet cloths and left. From these the garrison was soon separated by the fire, and now only the cartridges in the guns were left. These were fired now and then to indicate that the fort was not silenced. Thus in truth the work was held while there was a cartridge to fire or powder enough accessible to make one. The flagstaff, which had been hit nine times, was cut at about 1, and the flag was then nailed to the cut piece, and so raised upon the ramparts. At this time both officers and men were compelled to lie flat upon their faces in the casemates, and hold wet cloths to their mouths to escape suffocation. Soon after Ex-Senator Wigfall came to the fort with a flag of truce, which he wished held up while he spoke; but the batteries did not respect it. He, however, represented himself as an aid of General Beauregard, and agreed for the evacuation of Fort Sumter. It was afterward learned that he had spoken falsely, and had no authority whatever from General Beauregard. At 12.55 P. M. the flag of Fort Sumter was drawn down, and the fort was surrendered soon after upon honorable terms; the garrison to carry away the flag of the fort, and all company arms and property, and all private property; and all proper facilities to be afforded for their removal to any post in the United States the commander might elect. No men were hurt in Sumter by the fire of the enemy. It is reported by the secessionists that no men were either killed or wounded upon their side. A boat from the United States squadron outside, with a flag of truce, arrived at Morris' Island, with a request to be allowed to come and take Major Anderson and his forces.--(Doc. 52.)--Tribune, Times, Herald, and World.

To-day the President expelled from the Federal army, for refusing to act on a particular service, Captain William B. St. Johns, of the Third Infantry, and First Lieutenant Abner Smead, of the First Artillery.
The Legislature of Pennsylvania passed the war bill without amendment last evening. Previous to its passage, the news of the bombardment of Fort Sumter was announced, and produced a profound sensation. The bill appropriates five hundred thousand dollars for the purpose of arming and equipping the militia; authorizes a temporary loan; provides for the appointment of an Adjutant-General, Commissary-General, and Quartermaster-General, who, with the Governor, are to have power to carry the act into effect.--Phila. Enquirer.
To-day the Virginia Commissioners were formally received by the President at Washington, when they presented the resolutions under which they were appointed.--(Doc. 54.)
The attack upon Fort Sumter, and its surrender, instead of depressing, fires and animates all patriotic hearts. One deep, strong, overpowering sentiment now sweeps over the whole community — a sentiment of determined, devoted, active loyalty. The day for the toleration of treason — treason to the Constitution! defiance to the laws that we have made!--has gone by. The people have discovered that what they deemed almost impossible has actually come to pass, and that the rebels are determined to break up this Government, if they can do it. With all such purposes they are determined  to make an end as speedily as may be.--(Doc. 55.)--Times, April 15.
Bishop Lynch, Roman Catholic, at Charleston, S. 0., celebrated the bloodless victory of Fort Sumter with a Te Deum and congratulatory address. In all the churches allusions were made to the subject. The Episcopal Bishop, wholly blind and feeble, said it was his strong persuasion, strengthened by travel through every section of South Carolina, that the movement in which the people were engaged was begun by them in the deepest conviction of duty to God; and God had signally blessed their dependence on him. If there is a war, it will be purely a war of self-defence.--Tribune, April 16.
General Beauregard, in general orders to-day, congratulates “the troops under his command on the brilliant success which has crowned their gallantry, by the reduction of the stronghold in the harbor of Charleston.” --(Doc. 56.)
