The privateer Sumter.
--The Albany (N. Y.) Journal contains a letter from J. H. Vermilyea, U. S. N., of the U. S. steamer Crusader, which gives the following account of the entrance of the privateer Sumter into Cienfuegos:The Sumter first came in under American colors, and afterwards secession. The fort fired twice before she would come to an anchor outside, and then the Sumter prepared to fight; but four hundred soldiers arrived in the night, and it was not attempted. The men have plenty of money, and it is said five thousand dollars was taken from one of the brigs. We expect to leave to-morrow in search of her.--Her captain says he wants to fall in with us, and that he will blow his ship up before he will be taken. Trinidad, a little below this, is a great place for vessels in the sugar and molasses trade, more so than Havana.
