"Yes, sir. A man on a great bay horse. Three quarters of an hour ago."

"Was he riding fast?"

"Yes. Riding fast."

Marchmont galloped on, his two troopers behind him. Their steeds were good, but not so good as was his. He left them some way behind. The night grew old. The moon, which had risen late, was high in the heavens. The Englishman traversed a shadowy wood, then went by silvered fields. A cabin door creaked; an old negro put out a cautious head. "Has a courier passed, going to Williamsport?"

"Yaas, sah. Er big man on er big bay. 'Bout half er hour ergo, sah."

Marchmont galloped on. He looked back over his shoulder—his men were a mile in the rear. "And when I come up with you, my friend, what then? On the whole I don't think I'll ask you to turn with me. We'll go on to Williamsport, and there we'll hold the court of inquiry."

He touched his horse with the spur. The miles of road ran past, the air, eager and cold, pressed sharply; there came a feeling of the morning. He was now upon a level stretch of road, before him, a mile away, a long, bare hill. He crossed a bridge, hollowly sounding through the night, and neared the hill. His vision was a trained one, exercised by war in many lands. There was a dark object on the road before him; it grew in size, but it grew very slowly; it, too, was moving. "You've a tired horse, though, lieutenant!" said the aide. "Strain as you may, I'll catch you up!" His own horse devoured the ground, steadily galloping by the frosty fields, through the air of earliest dawn. Suddenly, before him, the courier from Kelly halted. Mounted against a faint light in the southwestern sky, he stood upon the hilltop and waited for the horseman from Frederick. The latter took at a gallop the remainder of the level road, but at the foot of the hill changed to a trot. Above him, the waiting horseman grew life-size. He waited, very quietly, Marchmont observed, sitting, turned in his saddle, against the sky of dawn. "Damned if I know if you're truly blue or grey!" thought the aide. "Did you stop to disarm suspicion, because you saw you'd be overtaken—"

Another minute and the two were in speaking distance; another, and they were together on the hilltop. "Good-morning!" said McNeill. "What haste to Williamsport?" He bent forward in the light that was just strong enough to see by. "Why—It is yesterday's comrade! Good-morning, Captain Marchmont!"

"We must have started," said Marchmont, "somewhere near the same hour. I have a communication from General Banks for the commander at Williamsport."

If the other raised his brows over the aide's acting courier twice in twenty-four hours, the action did not appear in the yet uncertain light. Apparently McNeill took the statement easily, upon its face value. "In that case," he said with amicableness, "I shall have the pleasure of your company a little longer. We must be about six miles out, I should think."
