The Potomac blockade — another success.
We have intelligence that two schooners were captured by our forces at Evansport on Saturday last, after having been badly injured by our batteries. The cargo of one consisted of 432 bales of hay and 500 barrels of camenc and the other was laden with wood. One steaming attached to the schooners was sunk and another damaged. It was reported last evening that firing was heard in the direction of Evansport on Monday, and it is quite probable we may soon have important news from that quarter.
