The two colonels walked out on the lawn. Military cloaks were thrown over their shoulders and all signs of merry-making were gone from their faces. They stood side by side and with military glasses were sweeping the horizon toward the river. Presently they saw Harry and Dalton standing under the boughs of the oak, and beckoned to them.

"You know?" said Colonel Talbot.

"Yes, sir, we do," replied Harry. "We saw General Stuart and his staff ride away, because a messenger had come, stating that divisions of Hooker's army were about to cross the Rappahannock."

"That is true, but we wish no panic here. Go back in the house, lads, and dance. Officers are scarcer there than they were a half hour ago. But you two lads will return to General Jackson before dawn, while Lieutenant-Colonel St. Hilaire and I will gather up our young men and return to our own place."

Harry and Dalton obeyed promptly, and took their places again in the dancing, but they soon discovered that the spirit was gone from it. The absence of Stuart, Sherburne and others almost as conspicuous was soon noted, and although those who knew gave various excuses, they were not satisfactory. Gradually the belief spread that the long vacation was over. After Fredericksburg the armies had spent four months in peace along the Rappahannock, but there was a certainty in the minds of all that the armed peace had passed.
