PRISONERS ON THE ISLAND. - Belle Isle now contains upwards of 4,700 Yankee prisoners of war, who are sheltered from the sun by excellent tents, and supplied with all the games of pastime and sport that their inclinations suggest. Upwards of five hundred more will go over to day. A few prisoners arrived yesterday. About one thousand wounded remain at the Libby prison, in the care of the Federal surgeons.
