"By de poker, but if him come up agin dat, him not know wheder him man or monkey," he said, doubling an enormous fist. "Massa Jim, yo not tall 'nough to look in at de window. Better leave dat to Tom. Yo go to de front; plenty chance of fightin' dere."

It was only another attempt of the big negro to place our hero out of danger, and Jim promptly scouted the suggestion.

"You'll go to your stations right off," he commanded. "If I whistle, you can come along and join me. The first thing to be done is to see if the fellow is in there."

"Dat sartin; I know him dere. I ready to swear it," declared Sam.

"Then come along."

Without more ado Jim led the way, and presently, when they were within a stone's throw of the hut, they separated, each to seek the position to which he had been appointed. Jim himself stole on tiptoe towards the window of the hut, and, having arrived at it, lifted his head inch by inch, and, pulling off his cap, stared into the room. Then he bobbed down again, and had circumstances permitted of it he would certainly have whistled; for there were five men assembled in the hut, and one of the number was undoubtedly the man for whom he and his friends had set out, the one, in fact, who had that very evening attempted to kill him. In a flash he recognized the ruffian. Then his eye ran swiftly round the circle grouped about a rough plank table, on which bottles and glasses were to be seen, and promptly the faces struck him as likenesses of those he had observed the evening before on a slip presented to all working on the canal. It was a police notification, and had been sent to Phineas so that, in appointing European labourers, he might beware of employing those whose portraits appeared. And Jim brought to memory the words beneath the portraits.

"The police of the canal zone are in search of a number of men, amongst them the above. It has come to their knowledge that a band of European thieves has gathered in the neighbourhood, and several robberies of Commission stores prove their arrival here. Any who recognize the above should at once give notice of their whereabouts. From foreign official sources we are informed that at least one of the men is a dangerous criminal, wanted for acts of violence to the person."

"Phew!" Jim went hot all over. He recollected that Phineas had spoken to him of these men, and had explained to him that it was not until after their arrival on the isthmus that the police received a warning from foreign parts.

"No doubt the fellows had made their last haunt too hot for them," he explained, "so, hearing from their comrades that America had brought a heap of valuable stores here, and that where there are workmen there must also be, often enough, large sums of money with which to pay their wages, these rogues came along to the isthmus, took posts with the gangs of labourers, and then laid their plans to rob. One of our pay offices was broken into and rifled a month ago. That put the police on the qui vive. Then came a robbery at the far end of the canal. The culprits were not discovered, but immediately afterwards the police received this information from abroad, together with photographs."

"Which they publish here for the information of canal officials," said Jim.
