"It seems to me," said Compton, "that we have been here already a week."
"Quite that," said Venning.
"The time has seemed long because you have been receiving new impressions."
"I thought it was a fish I received," murmured Compton.
"Each impression," continued the hunter, "is a sort of milestone in your memory, so that an hour crowded with several of these milestones will appear to be longer than a whole blank day. You will get used to such interrupted nights--that is, if our journey does not end here."
"Oh, come, sir, we have dodged them beautifully."
"The feeling of security is the beginning of disaster," said Mr.
Hume, oracularly. "The rule of the bush is to keep your eyes skinned."
"What is the order of the day, then?"
"The order of the day is to watch and wait. Venning will crawl on to the little island on our right and watch the south hank. You, Compton, will take the head of the large island on our left, and I will watch from the other end. If any of us see danger, we will give the whistle of the sand-piper. Each will take water and food, and each, of course, will keep himself hid."
"We take our guns, of course?"
"Best not. A gunshot would bring a host down upon us. Don"t be discouraged," continued the hunter, as he saw the boys" faces drop.
"We have got the advantage of position, and we"ve got grit--eh?"
He nodded cheerfully, and they smiled back, and then each crept out to his allotted post. The first part of the watch was by no means bad--so the boys decided when they had settled down, Venning under a bush palm and Compton behind a log. There was a pleasant freshness in the air; and as the broad river uncoiled under the mist, it disclosed fresh beauties, till the lifting veil revealed the wooded heights and the tall columns of smoke, grey against the dark of the woods and black against the indigo blue of the sky. They marked where the hippos stood with their bulky heads to the sun, and saw the crocodiles on the sands of other islands lying motionless with distended jaws. And then the birds came to the hunting. Strings of dark ibis, of duck, and storks; small kingfishers all bejeweled, and greater kingfishers in black and white. The air was full of bird- calls, of the musical ripple of waters, of the hum of the forest moved by the morning wind.
By-and-by, however, the sun got to work in earnest, and the pleasure went out of the watching as the air grew hot and steamy. The sand- flies and the mosquitoes found them out, and blessed the day that brought two tender white boys into their very midst. They gathered to the feast in clouds, but these boys were not there for the fun of the thing. They drew gossamer veils over the brims of their felt hats, and gathered them in about their necks. They pulled their soft high boots up to their knees and secured them there; and, moreover, they smeared an abomination of grease and eucalyptus oil over their hands. The mosquitoes set up a shrill trumpeting that could be heard ten paces away, and held a ma.s.s meeting to protest; whereupon the father of all the dragon-flies, a magnificent warrior in a steel- blue armour, saw that a conspiracy was afoot, and swept into the midst with a whirr and a snap, a turn here and a flash there, that scattered the host in a twinkling of a gnat"s eye.
The islands shimmered in the glare as if they were afloat; the hippos took to the water, and a deep and drowsy silence fell upon the great river. But man, ever restless, was astir, and through the stillness there was borne to the three a soft continuous humming, that merged quietly into the short, clamorous throbs of an engine at work under pressure.
The launch was afloat again! Mr. Hume caught the trail of the smoke first, and Compton next. They marked the course under the north bank right up to a bend about six miles off, and they judged that the launch had stopped there, as the smoke went up in a straight thin column. Then Venning saw a canoe dart out from the south bank, followed by two others from different points. The sun struck like fire on gun-barrel and spear-head, and gleamed on the wet paddles.
He moistened his parched lips with a taste of water from his filter- bottle, and gave the call. The answer came, and he drew his friends to him with a low whistling. As they came crouching, he pointed upriver.
"Three canoes put out. Two are hidden behind that outside island, and there is the other creeping round the end."
"Oh ay," said Mr. Hume. "If they"re after us, they will have placed outlooks in the tallest trees;" and with his gla.s.s he swept the forest.
"They could not see us at that distance."
"But they could see our boat as soon as we appeared in open water.
We"ll stay where we are."
"Then we shall need our guns."
"It is not our guns that will save us, my lad, but strategy. Any one could fire off a rifle, but it takes nerve to keep cool in readiness to do the right thing at the right time."
"But," said Compton, obstinately, "we don"t want to be caught undefended."
"Leave this matter with me," said the hunter, sternly. "See that crocodile asleep on that stretch of sand? He"s our best protector.
Why? Because he is asleep. The natives, seeing him, would think we were not near. We will, however, keep watch together."
They returned to the boat, made all ready for an instant departure, in case they were discovered, then settled down to wait and watch once more. Gradually the strain wore off, the old silence fell upon the scene, and their eyes grew heavy from sheer monotony. The night had seemed long, bat the day was worse.
Then the boys rubbed their eyes and lifted their heads. Where there had been a bare stretch of water white under the sun between two islands a quarter of a mile off, there appeared a long canoe, with a tall spearman standing in the bows, and a full crew behind.
The man in the bows looked straight down the channel to their lair, where in the narrow cut the Okapi lay hidden behind a screen of leaves. Then he moved his hand to the right, and the canoe, silently, without a ripple almost, skirted the island on that side, into whose reedy sides the men darted their glances. Again the hand was moved, and the long boat crept across to the island on the left, which was swept by the sharp suspicious eyes of the natives. Again the bowman directed his gaze into the narrow opening, and this time he looked long. There was one small island to pa.s.s, and if the canoe kept on the north side, it would have to come right into the hiding- place; if it kept to the south, it would reappear at the end of the pa.s.sage by which the Okapi had entered.
In either case, the danger of discovery seemed certain. The three pairs of eyes from behind the tall gra.s.s were glued to the man"s face. They saw him start, then move his hand to the left, and as the canoe went stealthily out of their view round the south side, they heard the sullen plunge made by a crocodile as, disturbed from his sleep, he took to the waters.
Then the three crept back to the boat. "Pull her through the screen," whispered the hunter, as he caught up his rifle, "but make no noise;" and he took up another position ash.o.r.e, this time facing the other end of the channel.
With great caution the boys coaxed the Okapi through the trailing branches, so that she would be hidden from view if the natives looked up the channel. Then they waited and waited for ages before the hunter showed himself.
"Well?" they asked in a whisper.
"They have pa.s.sed on."
"And?" they said, watching his face.
"I don"t quite like it. They may have no suspicions, but I think they have; for one man pointed up in this direction."
"If they suspected anything they would have stopped surely."
"Perhaps not. The native doesn"t like the look of a trap, and it maybe that they pa.s.sed on with the intention of returning at night.
Or they may have gone for the other boats." Mr. Hume stood up to glance sh.o.r.ewards.
"Would it not be better to move on?" said Venning.
"If we could be sure that we should not be seen from the land, that would be the move." He stroked his beard. "I guess we"ll move," he said, "just about dusk, for I"m pretty sure in my mind that they did take particular notice of this channel, and my policy is always to listen to your instincts."
"Instincts," muttered Compton; "call them nerves."
Mr. Hume laughed. "About the time you were born, d.i.c.k, I was playing a lone hand in Lo-Ben"s country as trader and hunter, when a loss of nerve would have meant loss of life. See! So just leave this to me, and shove her along."
Compton grinned back at the hunter, and tugged at his oar, for the levers clanked too loud for this work. They crept along to another berth a little way off, and tied up in the shadow of the bank; and they had scarcely settled themselves when they heard again the beat of engines. The launch was returning, and was returning in answer to a signal that the game had been found! A pungent smell of smoke suddenly reached them, and, standing up, they saw over the reeds that a fire had been made on one of the neighbouring islands.
That was the signal!
Glancing sh.o.r.ewards they saw that more canoes were putting off--dark smudges on the water, but growing clearer as the crews dashed the paddles. But there were enemies even nearer. As they pulled the Okapi closer into the shadows a boat swept into view, and, evidently obeying directions given from the island where the fire was, took up a position overlooking the first hiding-place of the Okapi. All the time the launch drew nearer, racing evidently to take advantage of the brief spell of light before the dark, and the canoes raced from the sh.o.r.e to take part in the great man-hunt. As they drew near, the fleet scattered, some going up-stream, others down, and the remainder dashing straight on in among the islands.
As they scattered to take up their positions, there came a report from the launch"s gun.
It was the signal for the drive to begin, and as the echo rolled away, a deep silence followed the previous uproar. The savage look- out men, standing erect in the sharp bows of the long canoes, motioned to the paddlemen to stop, and all heads were turned to the wind to catch any sound in case the hunted should attempt to move away. Fierce eyes were directed towards one spot, where the fire blazed on the island over against the place where the Okapi had laid up.
Not a whisper had come from the three in the boat. After they had first seen the signal smoke, which told them so plainly that Mr.
Hume"s suspicions were justified, they had crouched low, watching every move that was visible to them.
A canoe rounded their hiding-place and crept stealthily by towards the narrow pa.s.sage with its screen of bushes, every man fixing his gaze directly ahead, the broad nostrils quivering, and spears grasped in the hands that were not busy with the paddles.
