A few minutes after his conversation with Jim the party started, following the broad track through the grass along the foot of the hill. Reuben informed Mr. Blount of what Jim had told him.  
"By Jove, I think he is right," the settler said. "The track is as broad as it was, but it is nothing like so much trampled down; but if your fellow says the main body have gone over the hill, why are you following this track?"
 
Reuben gave his reasons, and said that his man had, before, had suspicions that the trackers were in communication with the wild blacks.
 
"He thinks that's why it is that they have so frequently failed, here, to catch any of these fellows."
 
"I shouldn't be at all surprised," Mr. Blount said savagely. "The best thing would be to put a bullet into each of the rascals' heads."
 
"I think Jim's idea is best," Reuben said. "Now that we have once got our eyes open, they won't be able to do us any more harm; and my black fellow will see we follow the trail right. I don't want them to see we have any suspicions of them, as that would put them on their guard; and by keeping our eye upon them, we may be able to turn the tables."
 
"That is so," Mr. Blount agreed. "What are you going to do, then?"
 
"I will call to them, in a minute or two, and tell them that it is your opinion that only a small portion of the flock have come this way. Then we will have a consultation and, no doubt, some of your friends will notice that the ground is not much trampled. Then we will decide to ride back to the point from which we started, and will follow the other trail."
 
"Yes, that will do very well," the settler agreed.
 
Reuben at once called to the trackers, who were trotting on ahead, and then ordered a halt. The two blacks came back.
 
"Joe," Reuben said, "Mr. Blount thinks that the main body of the flock have not come this way. He says he thinks only a hundred or two have come. The ground does not look to me anything like so much trampled as it was before we halted."
 
"I tink most of dem hab come along here," the tracker said sullenly.
 
"What do you think?" Reuben asked the other settlers, who had gathered round.
 
"I did not notice it before," Dick Caister said; "but now Blount has pointed it out, I agree with him entirely. There are nothing like the full number of sheep have passed along here. I should say that they have not gone along more than two or three deep."
 
There was a general chorus of assent.
 
"You can't have been keeping your eyes open," Reuben said to the trackers, sharply. "If you don't look sharp in future, we shall quarrel.
 
"Come, gentlemen, let us ride back to the halting place, and see if we cannot find out which way the main body have gone."
 
Ten minutes' riding took them back to their starting place.
 
"They must have gone over the hill," Reuben said. "They certainly have not kept along at the foot, or we should see their tracks in this long grass."
 
The trackers had exchanged a few words in a low tone, and they now moved up the hill, and began to examine the ground carefully.
 
"Some of dem have gone this way, captain."
 
"Of course they have," Mr. Blount said. "A blind man might see that."
 
The marks of the sheep were indeed plain enough to all, when their attention had once been drawn to the subject. On getting beyond the crest the trackers turned to the left, and Reuben saw that they felt it would be hopeless to attempt, further, to mislead a party containing several settlers who were perfectly capable of following the trail.
 
Jim had, since speaking to his master, remained in the rear of the troop. After three miles' riding across the downs, they again came down upon a flat country, thickly covered with brush. Here and there pieces of wool sticking to thorns were visible, and the trackers went steadily on for some little time. Then their pace became slower, and finally they stopped.
 
"Trail ended, captain."
 
"What do you mean by the trail ended?" Reuben asked angrily. "Why, I can see a piece of wool, on there ahead."
 
"Dat so, captain; but only a few sheep hab passed here."
 
Some of the settlers dismounted and, having examined the ground carefully, declared that they were of the same opinion as the trackers.
 
"Very well," Reuben said; "then in that case, we must go back again to the foot of the hill. They were all together there, and we must take up the trail afresh."
 
On reaching the foot of the hill, Jim and some of the settlers joined the trackers, and penetrated the bush in all directions. Each returned bringing in pieces of wool.
 
"It is plain enough," Reuben said, "what they have done. They have broken up into small parties, and have scattered. The question is, 'What are we to do now?'
 
"What do you think, Mr. Blount? You have had more experience than anyone here, and you are the most interested in our overtaking these rascals. What do you recommend?"
 
"I don't know what to recommend," the settler said. "They have no doubt done it to confuse us, in case we should follow so far, and avoid being thrown off the scent the other side of the hill. The band may really have scattered, and gone off in small parties to different parts of the bush; or again, they may have scattered with the understanding that they will meet again, at some given spot, which may be ten and may be fifty miles ahead."
 
"The worst of it is," Reuben said, "I fear now that there is an end of all chance of coming up with them, today; and now the question of water comes in. If we could have caught them before nightfall, the horses, having had a good drink at that stream, could have done very well till we'd gone another thirty miles; but as that seems hopeless, now, we must consider seriously what we had best do, before we go any further. Does anyone here know anything of the country ahead?"
 
There was a general silence.
 
"The horses can do very well, tomorrow, without water," Mr. Blount said. "They will chew the leaves of this scrub; and can, if pressed, hold on for even two or three days upon it."
 
"In that case," Reuben said, "let us go on. We will break up into three parties. One shall go straight forward, the other two moving to the right and left, each following the tracks as well as they can. We will not go much beyond a walk. We have five more hours of daylight yet, and the horses can manage another fifteen miles. I will halt, an hour before it gets dark, and light a fire. The smoke will be a guide to the other two parties, who should not be more than a couple of miles to the right and left, and they will then close in.
 
"If you can suggest any better plan than that, Mr. Blount, please do so. Of course, I see the objection that the blacks may make out the smoke, and will know that they are being followed."
 
"Yes, that is an objection," Mr. Blount said; "but the chances are that they will know it without your telling them. It is more than probable that some of them have remained behind, on the watch; and that they will have signalled our coming, long ago."
 
"Dey have done that, sar," Jim, who was standing close to Reuben's elbow, put in. "Jim saw smoke curl up from the top of de hill, just when we turned, when we lost the trail."
 
"Why didn't you tell me before, Jim?" Reuben asked.
 
"De captain didn't ask Jim any question. Jim thought de captain see it for sure."
 
"I didn't see it, Jim. I don't think any of us saw it. We were all too much occupied looking for the trail. Another time, you tell me what you see without my asking.
 
"Well in that case, Mr. Blount, there can be no harm in my making a smoke, as they know already that they are pursued. Will you take charge of the right hand party? Sergeant O'Connor will take command of the left. Do you each take a tracker with you. I will take my boy. Three constables will go with each of your parties, and four with me.
 
"Will you gentlemen please to divide up, so as to make seven altogether in each party, without the natives?"
 
"I need not tell you to keep a sharp lookout, Captain Whitney. We know the blacks are a very strong party and, now they know that they are pursued they may, as likely as not, make a stand."
 
"Yes, that is quite possible," Reuben agreed. "Will you please be careful that neither of your parties get more than two miles, at the outside, away from mine? We can hear the sound of rifles, at that distance. If either party fires, the others will of course hurry to their assistance. Now, let us move forward."
 
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."
 
"How do you know there are three black fellows, Jim? I can see marks, sometimes, of the sheep's feet; but I have not seen a man's footprint at all."
 
"Jim see 'em, captain, plain enough. When dey all follow sheep, not very plain to see; but sometimes, when de sheep want to scatter, Jim see one footmark on one hand and one on the other, and sure to be one man behind."
 
"How far are the sheep ahead, Jim, have you any idea?"
 
"Six, eight hours, sar, when dey pass here; but dere's no saying how far they are, now. May be long way on, may be only little way. Me tink dat they hab not gone so berry far; dat smoke berry thin, not see him more than ten miles."
 
"I wish you had said that before, Jim," Reuben said. "We would have kept together and have galloped on, and taken our chance of finding them."
 
"Might have found four or five of dem," Jim replied, "but de others all scattered. No good to find dem, till dey come together again."
 
"No, you are right there, Jim. We must catch them all together, if we can. There are some twelve hundred sheep, somewhere ahead. Mr. Blount said there were about fifteen hundred driven off. We have come upon a hundred dead ones, and two or three hundred may have taken that turn to the right. As you say, it would be no good coming upon thirty."
 
For four hours the party continued their journey.
 
"It is six o'clock," Reuben said, looking at his watch. "We will halt, now, and light that fire."
 
Two of the constables were told off to keep watch, some fifty yards in front; and the others dismounted, and gathered together materials for a fire. This was soon done, and the smoke mounted straight and clear, a signal to the other two parties to close in.
 
Suddenly a cry was heard from one of the sentries. The men stooping round the fire leaped to their feet, just in time to see one of the constables struck from his horse by a boomerang, while a dozen spears whizzed through the air at the other. He fell forward on his horse, which carried him up to the fire; as he fell from the saddle, as it stopped, he was caught by two of the others. Three spears had pierced him.
 
"Stand to your arms. Steady, for your lives," Reuben shouted.
 
"Jim, throw the horses at once, and fasten their legs.
 
"We must defend ourselves here," he continued, turning to the others, "until help comes."
 
Not a moment was lost. The little party threw themselves down in a circle, each taking shelter behind a bush; and Jim speedily got the eight horses down in the centre, for each party had with it three of the spare animals. The whole time, from the first alarm until all was ready to receive the natives, did not occupy two minutes.
 
The horses of the sentries had galloped wildly on, both having been struck by spears; and Jim had no difficulty with the remainder, which were all standing in a group when the alarm was given, the owners not yet having removed their saddles.
 
All was done without flurry or excitement, although the yells of the natives rose from the bush all round the............
