"Good luck!" said Colonel Cummings, going back to his maps.

"Thank you."

And just at that moment, as Lounsbury swung round on his heel, there rang out from the river a single pistol-shot. It echoed sharply against the barracks and went dying away upon the bluffs.


CHAPTER XI

A LITTLE STRATEGY

Fraser's shot drew many eyes to the river. For, in the winter time, any occurrence, however trifling, could get the instant attention of the lonely garrison. Troopers in various stages of dress came tumbling out upon the long porch at barracks; others looked from the many windows of the big frame structure; the washer-women and their hopefuls blocked the doorways of "Clothes-Pin Row"; officers everywhere—at headquarters, at the sutler's, in their homes—and their wives and families, up and down the "Line," remarked the signal. But when Lounsbury brought up beside Fraser, and the two seemed to be occupying themselves with nothing in particular, the onlookers laid the shot to an over-venturesome water-rat, and so withdrew from their points of vantage.

"What is it?" was the storekeeper's first breathless demand.

The young officer, hands on hips, nodded straight ahead. "You see those willows just below the cut?" he asked. "Well, there's a queer, black bunch in 'em."
