"You forget there is a God who still works miracles. And through earthly instruments! Remember the fur-chute!"

"But it is drawn up every night," the girl protested.

"To-night it cannot be, for the noise is coming from it. The Crees and voyageurs were unloading fur-bales. They have been careless and left it down. Or perhaps they have not finished. Pray Heaven they may not come back too soon!"

Undoubtedly the noise, as of someone crawling, was coming from the fur-chute, the long box-pipe of pine that projected like a spout from the lower room of the fur-house and slanted down over the stockades to within a few feet of the river's surface. It was used for the loading and unloading of pelts carried in canoes, the huge bales being hoisted or lowered by a stout rope which ran through the center on a pulley. The height of Fort La Roche above the water made such a contrivance necessary. It effected a tremendous saving of time and portaging up the steep.

The only drawback was that it afforded means of ingress to enemies, since an active man could pull himself up by the rope, and this the Nor'westers had overcome by hinging the fur-house end on a great wooden pin. Thus at will the spout could be raised like the arm of a derrick out of reach from anyone below.

That the chute was not raised now could hardly have been an oversight. Brochet knew that Ferguson was far too careful for that. It must mean that there was still work to be done. The priest sweated at every distant echo of voice or footfall for fear it heralded the return of the Nor'west voyageurs.

The scraping, crawling noise continued. While they strained to hear, their ears tense as those of listening deer, they caught a faint metallic sound from the room downstairs.

"Bolts," muttered Brochet, straightening up suddenly. "Now what does that mean?"

He was shown! The trapdoor behind them flew open and Black Ferguson's head and shoulders rose up. He had worked the ruse of coming back unheard. In his hand the priest could see a piece of binding cord drawn taut as if fastened to something under the powder-room's floor.

"Ho! Ho!" His huge laugh reverberated among the rafters. "Ho! Ho!"
