By-and-by, "Halt!" came, repeated along from the front, company after company. "Halt! a rail gone."

It was found without difficulty. The imbeciles who took it up probably supposed we would not wish to wet our feet by searching for it in the dewy grass of the next field. With incredible dollishness they had also left the chairs and spikes beside the track. Bonnell took hold, and in a few minutes had the rail in place and firm enough to pass the engine. Remember, we were not only hurrying on to succor Washington, but opening the only convenient and practicable route between it and the loyal States.

A little farther on, we came to a village,—a rare sight in this scantily peopled region. Here Sergeant Keeler, of our company, the tallest man in the regiment, and one of the handiest, suggested that we should tear up the rails at a turnout by the station, and so be prepared for chances. So "Out crowbars!" was the word. We tore up and bagged half a dozen rails, with chairs and spikes complete. Here, too, some of the engineers found a keg of spikes. This was also bagged and loaded on our cars. We fought the chaps with their own weapons, since they would not meet us with ours.

These things made delay, and by-and-by there was a long halt, while the
Colonel communicated, by orders sounded along the line, with the engine.
Homans's drag was hard after us, bringing our knapsacks and traps.

After I had admired for some time the beauty of our moonlit line, and listened to the orders as they grew or died along the distance, I began to want excitement. Bonnell suggested that he and I should scout up the road and see if any rails were wanting. We travelled along into the quiet night.

A mile ahead of the line we suddenly caught the gleam of a rifle-barrel.
"Who goes there?" one of our own scouts challenged smartly.

We had arrived at the nick of time. Three rails were up. Two of them were easily found. The third was discovered by beating the bush thoroughly. Bonnell and I ran back for tools, and returned at full trot with crowbar and sledge on our shoulders. There were plenty of willing hands to help,—too many, indeed,—and with the aid of a huge Massachusetts man we soon had the rail in place.

From this time on we were constantly interrupted. Not a half-mile passed without a rail up. Bonnell was always at the front laying track, and I am proud to say that he accepted me as aide-de-camp. Other fellows, unknown to me in the dark, gave hearty help. The Seventh showed that it could do something else than drill.

At one spot, on a high embankment over standing water, the rail was gone, sunk probably. Here we tried our rails brought from the turn-out. They were too short. We supplemented with a length of plank from our stores. We rolled our cars carefully over. They passed safe. But Homans shook his head. He could not venture a locomotive on that frail stuff. So we lost the society of the "J.H. Nicholson." Next day the Massachusetts commander called for some one to dive in the pool for the lost rail. Plump into the water went a little wiry chap and grappled the rail. "When I come up," says the brave fellow afterwards to me, "our officer out with a twenty-dollar gold piece and wanted me to take it. 'That a'n't what I come for,' says I. 'Take it,' says he, 'and share with the others.' 'That a'n't what they come for,' says I. But I took a big cold," the diver continued, "and I'm condemned hoarse yit,"—which was the fact.

Farther on we found a whole length of track torn up, on both sides, sleepers and all, and the same thing repeated with alternations of breaks of single rails. Our howitzer-ropes came into play to hoist and haul. We were not going to be stopped.
