CHAPTER XIX

As the night air vibrated with the first explosion Casey Dunne and McHale leaped from their beds, and rushed for the door, opened it, and stood listening. There they heard another and another.

"Dynamite!" cried McHale, reaching for his clothes. "I'll bet it's our dam. Jump into some pants, Casey. There's just a chance to get a sight of somebody."

They threw on clothes with furious haste, caught up weapons, and raced for the stables. Their haste communicated itself to their horses, which bolted before the riders were firm in the saddles. Casey, as they tore past the house, thought he caught a glimpse of white at Clyde's window; but just then he had his hands full with Shiner, who was expressing his disapproval of such unseemly hours by an endeavour to accomplish a blind runaway.

Halfway to the river they came upon the first evidence of dynamite in the form of a bit of wrecked fluming. Water poured down a sidehill from a mass of shattered boards and broken, displaced timbers. They scarcely paused to view the ruin, but rode for the dam. There was no dam. Where it had been, remained only a few forlorn and twisted posts between which the muddied water whispered softly. The work had been very complete. McHale swore into the night.

"Our own medicine! Well, watch us take it. We ain't like boys that can't build a little thing like a dam. Which way do you reckon them fellers went?"

"Try the old ford," said Casey. "It's all chance, anyway."

A mile downstream they came to the ford, where the river for a brief distance had broadened and shallowed. Fresh tracks of one horse led down to the water's edge. On the other side, where they emerged, they were still filled with muddy water.

"That's the cuss that blowed the flume," said McHale. "He's met up with another one or two here. They've gone on downstream, but we sure can't trail them in this light. What do we do?"

"Ride ahead and trust to luck," said Casey. "It's all we can do."
