Round 2d.—35th Ohio darkey came boldly to the scratch; as he only weighed sixty-five pounds more than his opponent, and with the slight difference of one foot six inches higher, he pitched in most valiantly, and received a splendid hit on the sconce, which made him feel as if a flea bit him. After full ten minutes skirmishing, during which time neither struck the other, both retired to the further corner of the ring, until time was called.

Round 3d.—Minnesota Ethiopian, who had been weakening in the pulse for some time, came up shaky, and was received with laughter by his opponent; but the little fellow hit out splendidly, and launched an eye-shutter at the stalwart form of the 35th darkey. First blood claimed for the 2d Minnesota.

Round 4th was, per agreement, a rough and tumble affair, as the spectators were growing impatient; and such "wool-carding" was never before exhibited. Both fought plucky; but the 2d Minnesota having but just recovered from a sick of fitness, as he said, was about being overpowered, when the officer of the day interfered; and thus ended the dispute for the time. Betters drew their money, as the fight was a draw.

Ball in Camp.

Last night we had a fancy-dress ball, a recherché affair, a fine dancing-floor having been laid down in Company I's ground. A first-rate cotillion band was engaged, and played up lively airs. Your correspondent had a special invitation to be present, and enjoyed the party amazingly.

The belles of the evening were Miss Allers, the Widow Place, Miss Stewart, Miss Austin, and Miss Dodge, all of Minnesota.

Miss Dodge wore an elegant wreath of red clover, mingled with beech-leaves, and was dressed in red and white—the red being part of a shirt, kindly furnished by one of the friends of the lady; the white was expressly manufactured by the Widow Place, dressmaker and milliner for this regiment.

Miss Stewart is a beautiful creature, of a bronzed hue, from excessive exposure to the sun. She also wore a wreath of young clover, mingled with bunches of wheat.

Miss Allers was rather undignified in her actions; her dress we thought too short at the bottom, and too high in the neck; however, Miss A. was dressed in Union colors, having an American flag for an apron, and blue and red dress, with a neat-fitting waste—of materials.

But the one in whom we felt the deepest interest was the Widow. She had all the grace and elegance of a hippopotamus, and her style was enchanting. She wore a low-necked dress, with a bouquet of cauliflowers and garlick in her bosom, a wreath of onion-greens in her hair, full, red dress, and elaborate hoops, which continually said, "Don't come a-nigh me." Her bashful behavior was the talk of the evening, and the gay Widow and your correspondent, when upon the floor, were the cynosure of all eyes. The dance continued until the Colonel ordered a double tattoo sounded, so that we could hear it. Several intruders were put out, for conduct unbecoming gentlemen. The ball was strictly private, as no commissioned officers were allowed to participate.
