But for the first time the terrier made a sound. He gave a whining bark almost human in its meaning, and threw himself at the legs of his master, pushing him backwards and over towards the road leading upon the bridge, as a collie guides sheep. Presently Ingolby felt the floor of the bridge under his feet; and now he hastened on, with outstretched arms and head bent forward, listening intently, the dog trotting beside, with what knowledge working in him Heaven alone knew.

The roar of the Rapids below was a sonorous accompaniment to Ingolby’s wild thoughts. One thing only he felt, one thing only heard—the men in Barbazon’s Tavern saying that the bridge should be blown up on the Saturday night; and this was Saturday night—the night of the day following that of the Orange funeral. He had heard the criminal hireling of Felix Marchand say that it should be done at midnight, and that the explosive should be laid under that part of the bridge which joined the Manitou bank of the Sagalac. As though in very truth he saw with his eyes, he stopped short not far from the point where the bridge joined the land, and stood still, listening.

For several minutes he was motionless, intent, as an animal waiting for its foe. At last his newly-sensitive ears heard footsteps approaching and low voices. The footsteps came nearer, the voices, though so low, became more distinct. They were now not fifty feet away, but to the delirious Ingolby they were as near as death had been when his fingers closed on the pistol in his room.

He took a step forward, and with passionate voice and arms outstretched, he cried:

“You shall not do it-by God, you shall not touch my bridge!
I built it. You shall not touch it. Back, you devils-back!”

The terrier barked loudly.

The two men in the semi-darkness in front of him cowered at the sight of this weird figure holding the bridge they had come to destroy. His words, uttered in so strange and unnatural a voice, shook their nerves. They shrank away from the ghostly form with the outstretched arms.

In the minute’s pause following on his words, a giant figure suddenly appeared behind the dynamiters. It was the temporary Chief Constable of Lebanon, returning from his visit to Tekewani. He had heard Ingolby’s wild words, and he realized the situation.

“Ingolby—steady there, Ingolby!” he called. “Steady! Steady! Gabriel Druse is here. It’s all right.”

At the first sound of Druse’s voice the two wreckers turned and ran.
