They reached that road at last, only to find it as lost as Atlantis,[70-2] ] under twenty feet of water! The Allegheny had overflowed her banks, and now there remained no way across, short of following the stream up to Pittsburgh and so around, a détour of many miles, long and evil.

"And that," said First Sergeant Price, "means getting to the party about four hours late. Baby-talk and nonsense! By that time they might have burned the place and killed all the people in it. Let's see, now: there's a railroad bridge close along here, somewhere."

They scouted till they found the bridge. But behold, its floor was of cross-ties only—of sleepers to carry the rails, laid with wide breaks between, gaping down into deep, dark space whose bed was the roaring river.

"Nevertheless," said First Sergeant Price, whose spirits ever soar at the foolish onslaughts of trouble—"nevertheless, we're not going to ride twenty miles farther for nothing. There's a railroad yard on the other side. This bridge, here, runs straight into it. You two men go over, get a couple of good planks, and find out when the next train is due."

The two Troopers whom the Sergeant indicated gave their horses to a comrade and started away across the trestle.

For a moment those who stayed behind could distinguish the rays of their pocket flash-lights as they picked out their slimy foothold. Then the whirling night engulfed them, lights and all.

The Sergeant led the remainder of the detail down into the lee of an abutment, to avoid the full drive of the storm. Awhile they stood waiting, huddled together. But the wait was not for long. Presently, like a code signal spelled out on the black overhead, came a series of steadily lengthening flashes—the pocket-light glancing between the sleepers, as the returning messengers drew near.

Scrambling up to rail level, the Sergeant saw with content that his emissaries bore on their shoulders between them two new pine "two-by-twelves."[72-1] ]

"No train's due till five o'clock in the morning," reported the first across.

"Good! Now lay the planks. In the middle of the track. End to end. So."
