"Will it be safe to light a fire, Dias?"
"Yes, that will make no difference. They are not likely to attack us at night. Savages seldom travel after dark, partly because they are afraid of demons, partly because they would be liable to be pounced upon by wild beasts. But I do not think there is any chance of their overtaking us until tomorrow. The man José saw may have had companions close at hand, but they will know that we are well armed, and will do nothing until they have gathered a large number and feel sure that they can overpower us. They will probably take up the track to-morrow at daylight; but we have made a long march, and can calculate that we shall find some defensible position before they overtake us. José and I will keep watch to-night."
"We will take turns with you, Dias."
"No, señor; my ears are accustomed to the sounds of the forests, yours are not. If you were watching I should still have no sleep."
The night passed without an alarm.
An hour before daylight Dias gave all the animals a good feed of corn, and as soon as it was light they again started. They were already some distance up the mountain, and after eight hours' travelling they arrived at a gorge that suited their purpose. For two hundred yards the rocks rose perpendicularly on each side of the stream, which was but some thirty feet wide. No rain had fallen for some days, and the water was shallow enough at the foot of the cliff for the mules to make their way among the fallen rocks, through which it rushed impetuously. At the upper end the cliffs widened out into a basin some fifty yards across.
"We cannot do better than halt here," Dias said. "In two or three hours we can form a strong breast-work on the rocks nearly out to the middle of the stream, where the current is too swift for anyone to make his way up against it."
"Are they likely to besiege us long, Dias?"
"That I cannot say; but I do not think they will give it up easily. Savages learn to be patient when roaming the forest in search of game. Their time is of no value to them; besides, they are sure to lose many if they attack, and will therefore try to get their revenge."
"They may have to give it up from want of food."
