A Ball Interrupted.
--The steamboat Iberia started from New Orleans recently on a pleasure excursion with a large number of Yankee officers and ladies. The Confederates were on shore, and gave her a salute as she was going up the river. A Yankee letter says:‘ At the time the Iberia was attacked, her passengers (among the number several ladies) were dancing in the cabin. The consternation when the first shot passed through the vessel is said to have been frightful. Regardless of the screaming of the women and the evident fact that the boat was loaded with passengers, the enemy continued to pour volley after volley among the people. Although several balls passed through the clothes of the passengers, in all of the firing, strange to say, but one person was wounded.
