"A crafty set of dogs," he declared, after one of these long conversations with his office at Colon. "They laid their plans most elaborately, and made every preparation to throw dust in our eyes. That explosion way over at Pedro Miguel wasn't the only little bit of by-play. It seems that they engaged a boatman to steal away from Colon this evening, and give us the impression that they were aboard; but that huge negro Tom put a spoke in their wheel. He happened to be in Colon, and reported to the office at once that he had seen a fire signal up by Gatun, way behind this house." "And guessed it was meant for someone down by the sea?" asked Phineas, rising from his seat at the receipt of such important information. "Major, this Jim and his servants have done good service to our people here. I'm glad that Tom has shown himself such an excellent constable." "He's one of the exceptions one finds amongst big men," declared the Major. "He's sharp, as sharp as a needle, for all his smiles and easy-going manner. He spotted this flare way back behind us, and looked well about him. He reported, a matter of two hours ago, that a boat had put off with some four men in her. Two of the crew at least he knew to be loafers about the streets of Colon, and one was the owner, a man of bad repute. Still, the fourth might have been one of the rascals we are after. So I sent out a steam launch, and her report has just reached me." "Well?" demanded Phineas shortly, while Jim leaned forward anxiously. "It wasn't one of the rascals; it was a blind, as you've intimated." The Police Major nodded promptly. "Number two of the schemes of those rascals has failed. My people have just returned, and the sergeant has 'phoned me the news. He overhauled this boat and went aboard her. The fourth individual was another well-known character from Colon, while the owner of the craft, thinking perhaps that he would get into trouble, and hoping to set matters right for himself, admitted that he had arranged to slip off when a fire signal was lighted. The sergeant left him out there to go where he liked, and steamed back as fast as his engine would carry him. This time the pursuit will hardly be by way of the Atlantic." "But perhaps by way of Panama, on to the Pacific," suggested Phineas. "Or into the bush; that's where I imagine they may have gone," said Jim. "It seems to me that we have every reason to suspect that that is the course they will have followed." His two companions in the room looked steadily at him. Before now they had known our hero to give common-sense solutions when there was a difficulty, and all through, since the moment when they had first known him, he had proved himself to be possessed of a level head, of that sharpness and shrewdness for which the American is notorious. It was therefore with a feeling of interest that they waited for him to speak.
