Both sides of the Xingu were lined by the dense forest, in which the vegetation is so luxuriant that it must be a source of never ending wonder to those who look upon it for the first time.  The river above made a sharp bend, shutting off the view so fully that from their position, it was impossible to tell how far they would be able to use the canoe without making another portage.

“We haven’t seen a person on our way here,” remarked the Professor, calmly surveying the river and shores; “and I hope Ashman will bring back a similar report, for we all need a full night’s rest.”

“How is that?”

Long touched the arm of his companion, as he asked the question, and pointed down stream in the direction of camp.

To the amazement of the Professor, three natives were seen standing on the very spot where they themselves had stood a brief while before, evidently scrutinizing the white strangers with profound wonder and curiosity.

They were dressed similarly to Bippo, Pedros and Quincal—­that is, with only a piece of cloth around the loins—­but they displayed a marked contrast in other respects.  They were taller, more athletic, with immense bushy heads of hair, enormous rings in their ears, while the hue of their skins was almost as dark as that of the native African.

One carried a long-bow and a bundle of arrows strapped behind his shoulders, while the others were armed simply with javelins or spears.

“Those fellows mean fight,” added Long.

“No doubt of it,” replied the Professor.

“But a Winchester will reach further than their arrows and spears, even if they are tipped with poison.”

“Possibly they may be friendly, if they can be convinced that we intend them no harm, and you know what an advantage it will be to us if able to trust all the natives on our return.”

Long could not share the confidence of his companion and favored a direct advance down the bank toward the savages.  If the latter preserved their armed neutrality, all would be well enough, but at the first sign of hostility he advocated opening fire on them.

Perhaps he was right in the declaration that anything like timidity in dealing with savages is the worst possible course.  While the rights of every barbarian should be respected, it is all important that he should know that such concession is made not through fear, but because the superior party wishes to be just and merciful.

The natives stood as motionless as statues for several minutes, during which the white men scrutinized them with an interest that may be imagined.

The first and most natural thought of our friends was that an encounter could be avoided by entering the forest on the right and passing round the savages, who, it was quite apparent, intended to dispute their return; but if such was really their purpose, they would have little trouble in heading off the whites in the dense wood, beside which, for the weighty reasons already named, it would have been exceedingly unwise to act as though afraid of the dusky natives.
