"Who?—why, anybody having occasion to. It's the easiest way to reach the wing dam that Sanderson built at the canyon inlet to turn the current against the right bank. Fitzpatrick sends a man over now and then to clear the driftwood from the dam."

"Anybody been over to-day?"

"No."

"How about the cow-puncher—Grigsby—who brought my horse over and got my bag?"

"He was riding, and he came and went by way of our bridge below the dam. You couldn't ride a horse over that hill path."

"You certainly could not," said Ballard grimly. "There is a chunk about the size of this shack gone out of it—dropped into the river, I suppose."

Bromley was frowning reflectively.

"More accidents?" he suggested.

"One more—apparently."

Bromley jumped up, sudden realization grappling him.
