"It is all in the game!" grinned Harry. "We came out here for excitement, and you mustn't complain when you get it."

After breakfast, which was keenly enjoyed, the Black Bear was beached on the cast banks and the injury to the propellers examined.

Some of the blades were broken while others were strained.

"Well," Harry said, as he scratched his head in deliberation, "we've got extra blades, and we've got the tools, and I don't know as we're in a hurry anyway. We've got all the time there is!"

"Not if we catch the Nelson before it gets out of the country," Jack objected. "This is the 22d of August, and the Nelson must have sighted Lima about the 14th, so you see we've got to do some sailing if we get to the headwaters of the Beni before the boys get back home."

If they had only known, the lads might not have been so anxious to get on, for the boys with the Nelson were having troubles of their own about that time. Besides, there were difficulties ahead much greater than those entailed by the breaking of the blades of the propellers.

They worked all day at repairing the injuries, and at night were ready to proceed. It was dark again, and there seemed to be a great commotion on sh.o.r.e.

"For one," Frank observed, "I don't like the idea of going on up an unknown river in the night. There are rapids, and there may be obstructions. And then we may follow off some tributary which will land us in some swamp after an all night ride."

"I'm not anxious to go on tonight," Harry contributed, "for I'd like to see what that mess on sh.o.r.e will amount to. There's something besides the appearance of the Black Bear exciting those fuzzy little natives, and we may miss something if we run away. I wouldn't like to do that."

So it was decided to remain where they were until morning. The panels were put up, leaving only the openings for ventilation, and the Wolf was brought close alongside.

Frank got the first watch in the drawing of sticks, and stationed himself at the prow, where he could look out on the river. Jack and Harry were soon asleep.

About midnight a great clamor arose on the west bank. In a moment it was echoed from the opposite sh.o.r.e. There was a beating of drums--the foolish drums which the natives made so crudely--and long chants, rising in the darkness like the monotonous melodies the boys had heard in the cotton fields of the South.

Frank shook Jack and Harry out of their bunks, much to the disgust of the two sleepy-heads. They did not need to ask questions as to the reason for this, for the chant was coming nearer, and the drums were beating like mad.

"They're arranging an attack!" Jack said, turning a searchlight out of the front loophole. "I can see half a dozen canoes hanging off and on at a bend above. I guess we made a mistake in stopping here."

"Perhaps we'd better drop down the river," Harry suggested. "I don't want those heathens swarming over the Black Bear."

Jack went to the stern and looked out on the swirling river from that point.

"If we do," he said, in a moment, "we'll bunt into a fleet of war canoes. We've got to put on all speed and drive ahead."

"Why not drop back?" asked Harry.

"Because," was the reply, "we can go up stream about as fast as we can go down stream, and the canoes can't. We'll shut everything tight but the loopholes and go through them like a shot through paper. If they board us we'll have to open up and drop them into the river with our automatics."

"Put the big light out in front then," Harry said, "and stand there and tell me which way to steer, and let her go!"

The next moment the Black Bear, closely followed by the Wolf, was nearing the canoes, now drawn up in line of battle in front.

CHAPTER XII

A BRIBE OF HALF A MILLION

"What do you want to talk about?" asked Ned, as Thomas Q. Collins advanced a step, both hands still high above his head, as an indication that he was unarmed.

"I want to reach an understanding with you," was the reply.

"About what?"

"About--well, about your errand here."

"Oh! Well, what about it?"

Collins hesitated a moment and then asked:

"Why can't I come to you and sit down? I'm not armed. This is not an easy or a dignified position for me to hold."

"You say you are not armed," Ned replied. "Will you say as much for the savages who are with you in this dirty game?"

"There are no savages here with me," Collins protested. "Your Indian killed one by throwing him from the ledge, one was killed when the Vixen burned and dropped, and one was shot by one of your boys. The other went away with the motor car. You must have seen them riding away?"

"There were five people with him when he first came out here in the car," Jackson said, under his breath. "Ask him where the other white man now is."

"Did you see the other white man?" asked Ned of Jackson.

"Not distinctly."

"Would you have recognized him if it had been Lyman?"

"I might. I can't say. I wasn't very near to them. They kept me scouting over the hills to keep them in sight."

"Well," Collins called out, impatiently, "are you going to let me come in for a talk? If not, I'll go back and bring some shooters out here."

Without answering that special question, veiled, as it was, with a threat, Ned asked the one proposed by Jackson.

"Where is the white man who was with you when you first came here in the car?"

"I did not come in a motor car," was the reply. "I came in the Vixen."

"That's a lie!" Jackson whispered. "The Vixen, if that is what they call their airship, never showed up until a few days ago. I tried to signal to the driver; or, rather, I did signal to him, but he ignored me. This man Collins came in with the car more than two weeks ago, and went out in it, too, and the other white man remained. The next time he came, he was in the Vixen."

"Who is that fellow who is filling you with prejudice against me?"

demanded Collins, presently. "It looks like a man wanted for stealing cattle from the Lyman ranch."

"Why didn't you communicate with him, if you were so hungry?" asked Ned of Jackson, suspiciously. "You say he has been here at least twice."

Jackson frowned and looked away. Then his forehead flushed and he said:

"I guess there's no use lying about it. I was accused of running cattle off the Lyman range. That is the man who accused me. I never did. He knows that. Now you know why I didn't approach him and ask for food."

"Well," insisted the boy, "why didn't you browse around and find the white man he left here? That is what he came in here for, isn't it--to hide some one he wanted out of the way?"
