Far better for him to have assisted in the escape of the doomed man than to have hurried off in search of the former comrades of Torres!

But Fragoso was away, and his assistance had to be dispensed with.

At daybreak Benito and Manoel left the raft and proceeded to Manaos. They soon reached the town, and passed through its narrow streets, which at that early hour were quite deserted. In a few minutes they arrived in front of the prison. The waste ground, amid which the old convent which served for a house of detention was built, was traversed by them in all directions, for they had come to study it with the utmost care.

Fifty-five feet from the ground, in an angle of the building, they recognized the window of the cell in which Joam Dacosta was confined. The window was secured with iron bars in a miserable state of repair, which it would be easy to tear down or cut through if they could only get near enough. The badly jointed stones in the wall, which were crumbled away every here and there, offered many a ledge for the feet to rest on, if only a rope could be fixed to climb up by. One of the bars had slipped out of its socket, and formed a hook over which it might be possible to throw a rope. That done, one or two of the bars could be removed, so as to permit a man to get through. Benito and Manoel would then have to make their way into the prisoner's room, and without much difficulty the escape could be managed by means of the rope fastened to the projecting iron. During the night, if the sky were very cloudy, none of these operations would be noticed before the day dawned. Joam Dacosta could get safely away.

Manoel and Benito spent an hour about the spot, taking care not to attract attention, but examining the locality with great exactness, particularly as regarded the position of the window, the arrangement of the iron bars, and the place from which it would be best to throw the line.

"That is agreed," said Manoel at length. "And now, ought Joam Dacosta to be told about this?"

"No, Manoel. Neither to him, any more than to my mother, ought we to impart the secret of an attempt in which there is such a risk of failure."

"We shall succeed, Benito!" continued Manoel. "However, we must prepare for everything; and in case the chief of the prison should discover us at the moment of escape----"

"We shall have money enough to purchase his silence," answered Benito.

"Good!" replied Manoel. "But once your father is out of prison he cannot remain hidden in the town or on the jangada. Where is he to find refuge?"

This was the second question to solve: and a very difficult one it was.

A hundred paces away from the prison, however, the waste land was crossed by one of those canals which flow through the town into the Rio Negro. This canal afforded an easy way of gaining the river if a pirogue were in waiting for the fugitive. From the foot of the wall to the canal side was hardly a hundred yards.

Benito and Manoel decided that about eight o'clock in the evening one of the pirogues, with two strong rowers, under the command of the pilot Araujo, should start from the jangada. They could ascend the Rio Negro, enter the canal, and, crossing the waste land, remain concealed throughout the night under the tall vegetation on the banks.

But once on board, where was Joam Dacosta to seek refuge? To return to Iquitos was to follow a road full of difficulties and peril, and a long one in any case, should the fugitive either travel across the country or by the river. Neither by horse not pirogue could he be got out of danger quickly enough, and the fazenda was no longer a safe retreat. He would not return to it as the fazender, Joam Garral, but as the convict, Joam Dacosta, continually in fear of his extradition. He could never dream of resuming his former life.

To get away by the Rio Negro into the north of the province, or even beyond the Brazilian territory, would require more time than he could spare, and his first care must be to escape from immediate pursuit.
