It seemed as if the interval of silence in which Peter waited, listening only to the beating of his own heart, was endless.

Then the well-known belch from the great chimney told him that his warning was being carried to every corner of the building. From the window he could see the men, hatless and alert, pouring out into the yard.

Eager to join in the work he rushed down-stairs and was soon in the thick of the excitement.

Immovable with surprise the men waited, the great frames of wet leather suspended in their hands.

Peter Strong stepped forward.

“I did, Mr. Tolman,” he answered quietly.
