Grogan uttered a disgusted grunt, as if keenly disappointed because apparently he had made a dismal failure in trying to fasten the robbery upon these two lads. Doubtless he had been figuring on what he would do with his share of the prize money, and hated to see his rosy visions fade away so soon.
"And this is that same little Tramp, sir," continued Jack, pleasantly; "as you can see for yourself if you take a look at the stern, where the name is painted in gold letters. We are unfortunate enough in having a boat that seems to resemble the one supposed to have been used in their flight down the river by the robbers. But if you care to wait long enough for me to get out some letters I have, I am sure you will be convinced of our entire innocence."
"Say no more, Jack," declared the captain, heartily. "I'm satisfied right now that we've been misinformed when told that a boat answering the description of the one in which those two yeggmen fled, was seen to enter here this afternoon; and that two young men were aboard her."
"What time in the afternoon, Captain?" asked Jack, quietly, though with a purpose in the question.
"The man who talked to me over the phone, said he had arrived in the suburb where he lived at four o'clock. He had been out in his motor, and was crossing a bridge here when the boat passed under, going up. He could not be sure to the minute, but reckoned that was somewhere around two p. m."
Jack turned to Jimmie. His face shone with eagerness, for a faint suspicion that had been creeping into his head was now rapidly becoming a certainty.
"Tell the captain, Jimmie, when we came in this creek," he said, quietly.
"Twelve minutes till four, it was, sir," replied Jimmie, promptly.
"Oh! what made you take such exact notice of the time, may I ask?" the officer went on, curiously, though plainly interested.
"We are compelled to make a memorandum of our stoppings. The conditions of the race forbid any boat to be moving south before eight in the morning, or after four in the afternoon. So I can show you in my notebook how an exact record is kept of such things. It will be figured on when the race is decided. We are going by stations you see, Captain, that are about two hundred miles apart. At each station we wait for the slowest boat, and then make a new start."
