Five minutes afterward the four boats started from the raft. After descending the Rio Negro they arrived near the bank of the Amazon, at the very place where Torres, mortally wounded, had disappeared beneath the waters of the stream.

CHAPTER VIII.
THE FIRST SEARCH

The search had to commence at once, and that for two weighty reasons.

The first of these was—and this was a question of life or death—that this proof of Joam Dacosta’s innocence must be produced before the arrival of the order from Rio Janeiro. Once the identity of the prisoner was established, it was impossible that such an order could be other than the order for his execution.

The second was that the body of Torres should be got out of the water as quickly as possible so as to regain undamaged the metal case and the paper it ought to contain.

At this juncture Araujo displayed not only zeal and intelligence, but also a perfect knowledge of the state of the river at its confluence with the Rio Negro.

“If Torres,” he said to the young men, “had been from the first carried away by the current, we should have to drag the river throughout a large area, for we shall have a good many days to wait for his body to reappear on the surface through the effects of decomposition.”

“We cannot do that,” replied Manoel. “This very day we ought to succeed.”

“If, on the contrary,” continued the pilot, “the corpse has got stuck among the reeds and vegetation at the foot of the bank, we shall not be an hour before we find it.”

“To work, then!” answered Benito.
