"Another of them anarchistic attempts," growled one of the men. "Guess this is too almighty queer fer anything. Here's spoil trains been sent runnin' down from the cut, and the same with diggers. Sleepers and suchlike laid on the rails in order to throw passenger trains off the metals, fires, and what not. This is the limit."

"It's one of the most serious difficulties we have had to face, boys," said one of the canal officials, coming upon the group of men at that moment. "I've just come along from the dock at Pedro Miguel, and there isn't a doubt that some rascal endeavoured to blow the whole place to pieces. It's Jim Partington's section, and he'd left everything safe and sound. There wasn't a rock drill working there, and hasn't been this three weeks past. Consequently there weren't any dynamite shots; but a man was seen creeping down that way soon after sundown. Guess he'd fixed to place his bomb right in the trench where the foundations are being laid; but something went wrong with it. He was blown to pieces; there were only scraps of him to be found."

There was a grunt of satisfaction at the news; the men felt that such a fate was only just retribution.

"But what damage has been done, boss?" asked one of the men anxiously, as if the success of the canal depended on the answer.

"None; in fact the explosion seems to have helped us. Young Jim Partington tells me he was making a requisition for a rock drill this coming week, as there was a heap of stuff to break down before the diggers could get at it. Well, he's saved the trouble. That explosion brought tons of stuff away, and now there's hardly need for a rock drill. Of course you've got to remember that it's dark 'way over there, and a man can't fix exactly what may have happened. But we made a quick, and, I believe, thorough survey of the place, and I should say that I've told you everything. This blessed cur who has been worrying us these weeks past has come by his deserts at last."

There was, in fact, not the smallest doubt that the rascally plot of Jaime and his followers had failed at the very beginning. Juan, who had accepted the post of honour, had disappeared from the scene swiftly and terribly. He had been hoist by his own petard, and, as the official had stated, there was little left to show that he had actually existed.

But still there was Jaime to reckon with, Jaime de Oteros and his fellows, and the reader need feel little surprise when he hears that, later on in the evening, there was another disturbance. It was discovered that the pay offices had been burgled, and that a vast sum of money had been removed. Then came an urgent telephone message to Ancon. The instrument at the club rang loudly and continuously, causing one of the men to go to it instantly. Jim, who had just returned from an inspection of his section, where the explosion had taken place, sat at a table near at hand, and, though there was no reason why the telephone should be calling him more than any other, he watched his comrade and listened.

"What's that? Say, who are you?" he heard the man demand. Then he suddenly looked over his shoulder, and if ever a man bore a startled expression it was this one. "Say, Jim, there," he called out, "they're ringing you from Gatun. It's Phineas Barton; there's trouble down there as well."

Jim was beside him in a moment, the receiver to his ear; and at once he recognized Phineas's voice, but strangely altered.

"Yes?" he asked as coolly as he could, though something set his heart thumping. "It's Jim at this end."
