In fact, it was the discovery of the irons abandoned by some slaves, and the roaring of the lion, that had caused the American's sudden disappearance.
He knew that he was discovered, and he had fled probably before the little party which he guided had reached the place where an attack had been arranged.

As for Negoro, whose presence Dingo had certainly recognized during these last days of the march, he must have rejoined Harris, so as to consult with him.

At any rate, several hours would pass before Dick Sand and his friends would be assailed, and it was necessary to profit by them.
The only plan was to regain the coast as quickly as possible.

This coast, as the young novice had every reason to believe, was that of Angola.

After having reached it, Dick Sand would try to gain, either to the north or to the south, the Portuguese settlements, where his companions could await in safety some opportunity to return to their country.
But, to effect this return to the coast, should they take the road already passed over?
Dick Sand did not think so, and in that he was going to agree with Harris, who had clearly foreseen that circumstances would oblige the young novice to shorten the road.
In fact, it would have been difficult, not to say imprudent, to recommence this difficult journey through the forest, which, besides, could only tend to bring them out at the place they had started from.
This would also allow Negoro's accomplices to follow an assured track.
The only thing they could do was to cross a river, without leaving any traces, and, later on, to descend its course.
