Doc. 155.-blockade of Charleston.
The officer remained by the Hilja for about twenty minutes, when he left. The boat's crew had a revolver each in a belt attached to the waist. Mr. Lockwood left the Hilja about 10 o'clock, and reached the city in his skiff, accompanied by a valuable boat hand, who remained faithful, although appearances indicated that the boy had only to open his mouth, when he might have had a passage to some other place than “Dixie's land.” The Hilja went  off during the day, and will proceed to the British Provinces. The British ship Monmouth, from Liverpool and the ship General Parkhill, from the same place, were seen off the bar yesterday and were ordered off, and we understand that the Niagara had previously sent off three other squarerigged vessels. During Sunday the Niagara went well off shore, accompanied by two of the above vessels, and while she was absent the British ship A. and A., Captain Hutchinson, from Belfast, stood in from the eastward, when the Niagara made after her; but the ship, having much the start, was run into shoal water, where the frigate could not well approach her, when the Niagara put about and proceeded south. Should the boats of the Niagara omit to board the A. and A. before morning, she may be got into port with the aid of steam. The race was anxiously watched from the wharves, and also by a party of gentlemen who were out in the pilot boat Rover, Captain Evans. They went alongside and spoke the ship.--Charleston Mercury, May 13.
