A meager hand was extended for an instant over a rock, in the air, and afterwards nothing further was seen, or heard, in that quarter, by the soldiers.

“Quite an extraordinary interruption,” said the astonished Sitgreaves, “and a letter of very mysterious meaning.”

“Oh! ’tis nothing but the wit of some bumpkin, who thinks to frighten two of the Virginians by an artifice of this kind,” said the trooper, placing the billet in his pocket. “But let me tell you, Mr. Archibald Sitgreaves, you were wanting to dissect, just now, a damned honest fellow.”

“It was the peddler—one of the most notorious spies in the enemy’s service; and I must say that I think it would be an honor to such a man to be devoted to the uses of science.”

“He may be a spy—he must be one,” said Lawton, musing; “but he has a heart above enmity, and a soul that would honor a soldier.”

The surgeon turned a vacant eye on his companion as he uttered this soliloquy, while the penetrating looks of the trooper had already discovered another pile of rocks, which, jutting forward, nearly obstructed the highway that wound directly around its base.

“What the steed cannot mount, the foot of man can overcome,” exclaimed the wary partisan. Throwing himself again from his saddle, and leaping a wall of stone, he began to ascend the hill at a pace which would soon have given him a bird’s-eye view of the rocks in question, together with all their crevices. This movement was no sooner made, than Lawton caught a glimpse of the figure of a man stealing rapidly from his approach, and disappearing on the opposite side of the precipice.

“Spur, Sitgreaves—spur,” shouted the trooper, dashing over every impediment in pursuit, “and murder the villain as he flies.”

The former part of the request was promptly complied with, and a few moments brought the surgeon in full view of a man armed with a musket, who was crossing the road, and evidently seeking the protection of the thick wood on its opposite side.

“Stop, my friend—stop until Captain Lawton comes up, if you please,” cried the surgeon, observing him to flee with a rapidity that baffled his horsemanship. But as if the invitation contained new terrors, the footman redoubled his efforts, nor paused even to breathe, until he had reached his goal, when, turning on his heel, he discharged his musket towards the surgeon, and was out of sight in an instant. To gain the highway, and throw himself into his saddle, detained Lawton but a moment, and he rode to the side of his comrade just as the figure disappeared.
