With Jim in advance, Reuben's party moved on, the black carefully examining the ground and bushes as he went; and occasionally, somewhat to Reuben's surprise, rising from the stooping position in which he was walking, and looking back over his shoulder. The motive was explained when Jim exclaimed:
"Dere, captain, dere are de signals again."
Reuben turned in the saddle. On the crest of the hill behind him were three columns of smoke. Scarcely had he looked at them when the smoke ceased to ascend, as if the fires had been suddenly put out.
"That's to tell them that we have divided in three parties?" Reuben asked the black.
Jim nodded, and proceeded on his way again.
"That's awkward," Reuben said, "I must warn the other two parties."
So saying, he at once ordered two of the constables to ride right and left and warn the others, who were not as yet more than a quarter of a mile on either hand, that the natives were aware that they had broken up, and that the greatest caution must, therefore, be observed. In ten minutes the two constables returned, having performed their mission.
Although he had no reason to believe that the blacks were within ten miles of him, Reuben now took the precaution of sending one constable out on each flank, to a distance of fifty yards. A third was directed to keep with Jim, fifty yards ahead of the main body; consisting of Reuben himself, a constable, and two colonists. Occasionally Reuben rode forward to question Jim.
"How many sheep do you think have gone along the track you are following?"
"About thirty sheep, and three black fellow."
