In fact, almost at their heels rose a cloud of dust, and two or three cavalrymen rode out on the bank of the river. They appeared surprised at the line of earthworks, and the blue coats that here and there showed plainly. In a few minutes more the bank was lined with rebel horsemen.

"Why doesn't he light the fuse?" said the Commander-in-chief, nervously looking toward the bridge.

As he spoke a man ran up the track from the bridge; he turned and looked back two or three times as if expecting something to happen. But nothing happened.

"It failed to go off," said the man, out of breath, as he jumped into the trench.

The Judge scowled at him. "Let go that battery," he said. "Commence firing."

At the first discharge one of the old cannons burst, luckily hurting no one, and the straggling volley that followed only showed to the enemy the weakness of their opponents. A rebel with a powerful field-glass had climbed a tree and taken in the situation. The enemy was preparing for an advance. That was evident.

"Hang that fool!" said the Judge; "if he'd kept his wits about him, we'd be safe. I don't believe he waited to strike a match. They could never ford the river."

But he or no one else had seen a figure in a uniform much too big for his small body steal across the track and crawl on all-fours down the embankment on the further side. All at once they saw him emerge into sight and dive into the shallow of the bridge. It was Will Tevis.

Just as the cavalry were preparing to charge, he came into sight again, running swiftly down the middle of the track. A faint smoke arose from the bridge entrance, several shots were fired at him; but on he came. The intrenchments now broke out into flame just as there came a terrific roar, a bursting rending sound, and the bridge disappeared. Will Tevis in the ill-fitting uniform was a hero. The rebels were forced to keep the other side of the swollen river, but exchanged shots for some time before they drew away.

Coming up the hill late in the evening Hosmer and Will met Skinny. "Where have you been?" they asked.
