and the three remained unharmed.
Van had the satisfaction of seeing two of the men in the pursuing boat fall under the fire made by himself and companions.
But Doc Clancy, though continually exposed, had not been hit.
Though the villain seemed to bear a charmed life, he concluded to proceed a little more cautiously.
He gave orders to the men to make a circle and row around so as to get on the other side of the boat.
When Van saw this he began to grow very uneasy.
Our three friends were truly in a bad box. If they attempted to row the boat so as to get away from Clancy and his crowd, they would surely be shot down; and if they remained quietly where they were it would only be a question of time before they would be wiped out.
Before they had time to decide upon what action to take they were astonished to hear a number of rifle shots up the river.
They lifted their heads quickly and glanced at those who were pursuing them.
Doc Clancy and his gang were making for the shore with all their might.
And no wonder! for down the river a boat was being rapidly rowed by half a dozen stalwart blacks.
In the bow was a small swivel cannon, the muzzle of which pointed at the miscreants in the boat in a threatening manner.
Standing upright in the boat were three white men, who were armed to the teeth.
"Hurrah!" yelled Van, waving his hat. "You are just in time, friends."
An answering cheer came from the boat, and our friends breathed a sigh of relief.
As soon as Doc Clancy reached the shore he sprang into the tall reeds and disappeared, followed by his four surviving allies.
Five minutes more and the approaching boat reached our friends.
Van explained who he and his companions were in a very few words.
The three men who had come to their rescue at such an opportune moment shook hands with them in a cordial manner, and made the drifting boat fast to their own.
"Now," said the younger of the strangers, who was not over twenty-three years of age, "since you have told us who you are, I'll tell you who and what we are. We are three Englishmen, who have come to this continent to make explorations and endeavor to find some wonderful spot where the foot of civilized man has never trod. My name is Jack Howard; this gentleman on my right is Prof. Drearland, who intends to write a book on what we discover; and the other gentleman is Dr. Pestle, who came with us to keep us in good health by aid of the large stock of medicines and hard-earned experience he has with him."
"I am sure we are very glad to meet you all," returned Van, with a tone of deep sincerity. "But who are those men who attacked us? One of them we know, but the others are strangers."
"They are six men whom we hired to accompany us on our trip. Yesterday morning they struck for more wages, and because their demand was refused they attempted to kill us and take our outfit from us. We got the best of it, however, and they took to the forest and left us. This morning we heard rifle shots down the river, and thought we would come down and see what was in the wind."
"If there was six of 'em when they left you, there are only four now," remarked Lank Edwards, in a grim manner. "Two of ther villains have turned up their toes."
"Yes," put in Van; "but they have got Doc Clancy with them, and he is a match for any two ordinary men, as far as wickedness goes."
"Suppose you go up to our camp with us?" said Jack Howard, after a pause.
"Certainly," returned our hero. "We have got no other place to go just at present."
Howard gave the word, and the blacks began rowing the boat up the stream with long, steady strokes.
Though Van was some years his junior, Jack Howard took a strong notion to him, and as he was one of those blunt kind of fellows, he was not long in telling him so.
"It is mutual, I assure you," returned our hero; and the two from that moment became inseparable friends.
About a mile up the river the boats came to a stop on the left bank.
It was a very picturesque spot. The gorgeous African flowers of many hues, trailing vines, broad-leafed and giant cacti could be seen on every hand.
On a little knoll in the midst of these surroundings was the camp of the English explorers.
Two tents were pitched in the background, which served to keep off the dew while the men slept.
The negroes, who had been hired in place of the villainous whites, slept on the ground, close to burning fires, without any covering over them, unless it rained, and in that case Jack Howard told them they could haul the boat up and crawl under it.
After Van Vincent had announced his intention of hunting down Doc Clancy until he had been caught, Jack Howard offered to go in with him in the enterprise if he and his two companions would join the exploring party.
Van broached the subject to the mate and Gregory, and they readily agreed to it.
"Very well," said our hero to Howard, "your offer is accepted. We join your party and proceed with you in your explorations, so long as we do not turn from the trail of Doc Clancy."
"We will follow him, even if he goes to the very heart of this wild continent!" exclaimed Jack Howard, warmly.
The party remained in camp until slightly past noon, and they would not have left it then had it not been that an unforeseen circumstance took place.
While they were eating dinner one of the blacks came rushing up with the intelligence that the bad white men had just gone up the river in their boat.
The river was nearly straight at this point, and, rushing down to the water's edge, Van and Jack Howard saw Doc Clancy and his allies proceeding rapidly up the stream.
Already they were over half a mile away, and our friends did not deem it worth while to shoot at them.
But the camp was quickly broken up and all its belongings packed in the boat owned by the Englishmen, which was strong and commodious, and large enough for all hands.
Being aware of this fact, our hero concluded to leave their boat where it was.
When everything was in readiness all hands got into the boat, and the blacks started to row up the river in the wake of Doc Clancy.
CHAPTER VI.
A SLIGHT ADVENTURE
The boat owned by the explorers was much heavier than that in which Doc Clancy and his villainous crowd had gone up the river.
Thus the latter could be rowed faster, and it did not take our friends long to see that they were gradually being left behind.
"Our intention was to follow this river until we reached the branch that flows northward," said Jack Howard. "We then would go up that as far as we could, and then make the rest of our travels on foot. The man you call Doc Clancy is leading us over the very course we want to take, so far."
"But
