He did not wear a uniform, and therefore he did not belong to the Texan Rangers; for Deck had fought them, and knew how they were clothed. This struck him as an important point; for he had made sure before he rose from his seat that his carbine, slung at his back, was in condition for instant service. His regulation pistols were in the holsters on his horse; but he had supplied himself with a small revolver at Fort Bedford, for there was a tendency with fresh recruits to overload themselves with weapons on entering active service, and thousands of dollars worth of such were thrown away when they became a burden.
The stranger was dressed like a mechanic; and he seemed to be examining the planking of the bridge, which is not usually a matter of vital importance in such a structure for railroad purposes. The man stopped whistling, and began to use a middling-sized sledge-hammer, directing his blows at the heads of the spikes under his feet. Then he dropped the hammer, and picked up an adze, with which he trimmed off the projecting edge of a plank. Deck thought this was very strange work for a man to be doing at such a time, and in such a place.
But the mechanic was whistling a Union air; and this fact seemed to make it all right, and prevented him from having a suspicion that all was not right in the presence of the man on the bridge. The railroad in Kentucky was a loyal institution, as it was a disloyal one farther South. Deck therefore came to the conclusion that he was an employee of the company. He decided to interview the stranger, and ascertain more precisely who and what he was.
In matters of military duty Deck was a close constructionist; and the first question he asked himself was whether or not he ought to leave his post, even to go a distance of forty feet. His sole occupation till he received the signal to hoist the flag, was to watch for it; and he kept his father's plumed hat in sight all the time. But he could see the handkerchief when it was waved as well from behind the fence as at the flagstaff; or, at most, he had only to step back a few paces to enable him to command a full view of the expected battle-ground, and of the hill behind which Captain Truman was posted with his command.
He did not for an instant lose sight of his sole duty; but he walked a few paces at a time towards the fence, and then looked back, to make sure that he could see the plume of the major. As it was in sight all the time, he continued to advance very slowly. When he reached the end of the fence the centre of his watch was still to be seen, and nothing seemed to be in progress in any of the roads visible from his position.
Just at the moment when he was almost within speaking distance of the mechanic, who had ceased to whistle, the latter picked up his tools and moved to the other end of the fence, where he began to hammer the spikes again. The man appeared to take no notice of him, or even to be aware of his presence. Assured that he could see the skirmishers who had been sent beyond the hill if they were driven in, he continued to advance still farther, though he went to the middle of the bridge, where the fence did not obstruct his view.
Deck wanted to know more about the man with the sledge and the adze. The flag was to be hoisted as a signal for the second company to attack the enemy in the flank or rear, while the first engaged them in front. The fight must begin before the signal could be required, and the signalman would have abundant notice when the firing began that his services would soon be required. The fence was less than a hundred feet in length, and he had not far to go to confront the mechanic.
Keeping the cross-roads in view till the fence shut it out, he made a quick movement to the immediate vicinity of the workman, who was hammering away with the sledge with all his might. He made so much noise that he could not hear the steps of the soldier.
"What are you doing here?" shouted Deck.
