That man was Negoro. The rascal, on getting his letter at Kazonnde, instead of embarking at once for America, had left his native escort for a while, and returned to the scene of his crime to secure the treasure which he had left buried at a little distance in a spot that he had marked. At this very moment he was in the act of digging up the gold he had concealed; some glistening coins scattered here and there betrayed his purpose; but in the midst of his labours he had been startled by the dashing forward of a dog; another instant, and the dog had fixed itself upon his throat, whilst he, in an agony of desperation, had drawn his cutla.s.s and plunged it deep into the creature's side.

Hercules came up at the very climax of the death-struggle.

"You villain! you accursed villain! I have you now!" he cried, about to seize hold of his victim.

But vengeance was already accomplished. Negoro gave no sign of life; death had overtaken him on the very scene of his guilt. Dingo, too, had received a mortal wound; he dragged himself back to the hut, lay down beside the remains of his master, and expired.

The sad task of burying Vernon's bones, and laying his faithful dog beside them having been accomplished, the whole party was obliged to turn their thoughts to their own safety. Although Negoro was dead, it as very likely that the natives that he had taken with him were at no great distance, and would come to search for him.

A hurried conference was held as to what steps had best be taken. The few words traceable on the paper made them aware that they were on the banks of the Congo, and that they were still 120 miles from the coast. The fall just ahead was probably the cataract of Memo, but whatever it was, no doubt it effectually barred their farther progress by water. There seemed no alternative but that they should make their way by one bank or the other a mile or two below the waterfall, and there construct a raft on which once again they could drift down the stream. The question that pressed for immediate settlement was which bank it should be. Here, on the left bank, would be the greater risk of encountering the negro escort of Negoro, while as to the farther sh.o.r.e they could not tell what obstacles it might present.

Altogether Mrs. Weldon advocated trying the other side, but d.i.c.k insisted upon crossing first by himself to ascertain whether an advance by that route were really practicable.

"The river is only about 100 yards wide," he urged; "I can soon get across. I shall leave Hercules to look after you all."

Mrs. Weldon demurred for a while, but d.i.c.k seemed resolute, and as he promised to take his gun and not to attempt to land if he saw the least symptom of danger, she at last consented, but with so much reluctance that even after he had entered the canoe she said,-

"I think, d.i.c.k, it would be really better for us all to go together."

"No, Mrs. Weldon, indeed, no; I am sure it is best for me to go alone; I shall be back in an hour."

"If it must be so, it must," said the lady.

"Keep a sharp look-out, Hercules!" cried the youth cheerily, as he pushed off from the land.

The strength of the current was by no means violent, but quite enough to make the direction of d.i.c.k's course somewhat oblique. The roar of the cataract reverberated in his ears, and the spray, wafted by the westerly wind, brushed lightly past his face, and he shuddered as he felt how near they must have been to destruction if he had relaxed his watch throughout the night.

It took him hardly a quarter of an hour to reach the opposite bank, and he was just preparing to land when there arose a tremendous shout from about a dozen natives, who, rushing forward, began to tear away the canopy of gra.s.s with which the canoe was covered.

d.i.c.k's horror was great. It would have been greater still if he had known that they were cannibals. They were the natives settled at the lacustrine village higher up the river. When the piece of thatch had been knocked off in pa.s.sing the piles a glimpse had been caught of the pa.s.sengers below, and aware that the cataract ahead must ultimately bring them to a standstill, the eager barbarians had followed them persistently day by day for the last eight days.

Now they thought they had secured their prize, but loud was their yell of disappointment when on stripping off the thatch they found only one person, and that a mere boy, standing beneath it.

d.i.c.k stood as calmly as he could at the bow, and pointed his gun towards the savages, who were sufficiently acquainted with the nature of fire-arms to make them afraid to attack him.

Mrs. Weldon with the others, in their eagerness to watch d.i.c.k's movements, had remained standing upon the sh.o.r.e of the river, and at this instant were caught sight of by one of the natives, who pointed them out to his companions. A sudden impulse seized the whole of them, and they sprang into the canoe; there seemed to be a practised hand amongst them, which caught hold of the rudder-oar, and the little craft was quickly on its way back.

Although he gave up all as now well-nigh lost, d.i.c.k neither moved nor spoke. He had one lingering hope yet left. Was it not possible even now that by sacrificing his own life he could save the lives of those that were entrusted to him?

When the canoe had come near enough to the sh.o.r.e for his voice to be heard, he shouted with all his might,-

"Fly, Mrs. Weldon; fly, all of you; fly for your lives!"

But neither Mrs. Weldon nor Hercules stirred; they seemed rooted to the ground.

"Fly, fly, fly!" he continued shouting.

But though he knew they must hear him, yet he saw them make no effort to escape. He understood their meaning; of what avail was flight when the savages would be upon their track in a few minutes after?

A sudden thought crossed his mind. He raised his gun and fired at the man who was steering; the bullet shattered the rudder-scull into fragments.

The cannibals uttered a yell of terror. Deprived of guidance, the canoe was at the mercy of the current, and, borne along with increasing speed, was soon within a hundred feet of the cataract.

The anxious watchers on the bank instantly discerned d.i.c.k's purpose, and understood that in order to save them he had formed the resolution of precipitating himself with the savages into the seething waters

Nothing could avail to arrest the swift descent. Mrs Weldon in an agony of despair waved her hands in a last sad farewell, Jack and Benedict seemed paralyzed, whilst Hercules involuntarily extended his great strong arm that was powerless to aid.

Suddenly the natives, impelled by a last frantic effort to reach the sh.o.r.e, plunged into the water, but then movement capsized the boat.

Face to face with death, d.i.c.k lost nothing of his indomitable presence of mind. Might not that light canoe, floating bottom upwards, be made the means for yet another grasp at life? The danger that threatened him was twofold, there was the risk of suffocation as well as the peril of being drowned; could not the inverted canoe be used for a kind of float at once to keep his head above water and to serve as a screen from the rushing air? He had some faint recollection of how it had been proved possible under some such conditions to descend in safety the falls of Niagara.

Quick as lightning he seized hold of the cross-bench of the canoe, and with his head out of water beneath the upturned keel, he was dashed down the furious and well-nigh perpendicular fall.

The craft sank deep into the abyss, but rose quickly again to the surface. Here was d.i.c.k's chance, he was a good swimmer, and his life depended now upon his strength of arm.

It was a hard struggle, but he succeeded. In a quarter of an hour he had landed on the left hand bank, where he

[Ill.u.s.tration: The bullet shattered the rudder scull into fragments]

was greeted with the joyful congratulations of his friends, who had hurried to the foot of the fall to a.s.sure themselves of his fate.

The cannibals had all disappeared in the surging waters. Unprotected in their fall, they had doubtless ceased to breathe before reaching the lowest depths of the cataract where their lifeless bodies would soon be dashed to pieces against the sharp rocks that were scattered along the lower course of the stream.

CHAPTER XX.

A HAPPY REUNION.

Two days after d.i.c.k's marvellous deliverance the party had the good fortune to fall in with a caravan of honest Portuguese ivory-traders on their way to Emboma, at the mouth of the Congo. They rendered the fugitives every a.s.sistance, and thus enabled them to reach the coast without further discomfort.

This meeting with the caravan was a most fortunate occurrence, as any project of launching a raft upon the Zaire would have been quite impracticable, the river between the Ntemo and Yellala Falls being a continuous series of cataracts. Stanley counted as many as sixty-two, and it was hereabouts that that brave traveller sustained the last of thirty-one conflicts with the natives, escaping almost by a miracle from the Mbelo cataract.

Before the middle of August the party arrived at Emboma, where they were hospitably received by M. Motta Viega and Mr. Harrison. A steamer was just on the point of starting for the Isthmus of Panama; in this they took their pa.s.sage, and in due time set foot once more upon American soil.

Forthwith a message was despatched to Mr. Weldon, apprising him of the return of the wife and child over whose loss he had mourned so long On the 25th the railroad deposited the travellers at San Francisco, the only thing to mar their happiness being the recollection that Tom and his partners were not with them to share their joy.

Mr. Weldon had every reason to congratulate himself that Negoro had failed to reach him. No doubt he would have been ready to sacrifice the bulk of his fortune, and without a moment's hesitation would have set out for the coast of Africa, but who could question that he would there have been exposed to the vilest treachery? He felt that to d.i.c.k Sands and to Hercules he owed a debt of grat.i.tude that it would be impossible to repay; d.i.c.k a.s.sumed more than ever the place of an adopted son, whilst the brave negro was regarded as a true and faithful friend.

Cousin Benedict, it must be owned, failed to share for long the general joy. After giving Mr. Weldon a hasty shake of the hand, he hurried off to his private room, and resumed his studies almost as if they had never been interrupted. He set himself vigorously to work with the design of producing an elaborate treatise upon the "Hexapodes Benedictus" hitherto unknown to entomological research. Here in his private chamber spectacles and magnifying-gla.s.s were ready for his use, and he was now able for the first time with the aid of proper appliances to examine the unique production of Central Africa.

A shriek of horror and disappointment escaped his lips. The Hexapodes Benedictus was not a hexapod at all. It was a common spider. Hercules, in catching it, had unfortunately broken off its two front legs, and Benedict, almost blind as he was, had failed to detect the accident. His chagrin was most pitiable, the wonderful discovery that was to have exalted his name high in the annals of science belonged simply to the common order of the arachnidae The blow to his aspirations was very heavy; it brought on a fit of illness from which it took him some time to recover.

For the next three years d.i.c.k was entrusted with the education of little Jack during the intervals he could spare from the prosecution of his own studies, into which he threw himself with an energy quickened by a kind of remorse.

"If only I had known what a seaman ought to know when I was left to myself on board the 'Pilgrim,' " he would continually say, "what misery and suffering we might have been spared!"

So diligently did he apply himself to the technical branches of his profession that at the age of eighteen he received a special certificate of honour, and was at once raised to the rank of a captain in Mr. Weldon's firm.

Thus by his industry and good conduct did the poor foundling of Sandy Hook rise to a post of distinction. In spite of his youth, he commanded universal respect; his native modesty and straightforwardness never failed him, and for his own part, he seemed to be unconscious of those fine traits in his character which had impelled him to deeds that made him little short of a hero.

His leisure moments, however, were often troubled by one source of sadness; he could never forget the four negroes for whose misfortunes he held himself by his own inexperience to be in a way responsible. Mrs. Weldon thoroughly shared his regret, and would have made many sacrifices to discover what had become of them. This anxiety was at length relieved.
