"Is it then for you to repeat to me your sinister predictions that you stop me thus?" he cried.

"By no means, your Excellency; I do not admit my right either to control your acts or to oppose your plans. I have warned you, that is all. I am now at your orders."

"You have not, I hope, whispered a word to anyone of these absurd crotchets which possess your brain?"

"What use would it be, my lord, to speak without your authority of what you term crotchets, and what I term certainties? The soldiers placed under my orders know as well as I do what awaits them in the desert. As to your slaves, what use would it be to frighten them beforehand? Is it not better to leave them in entire ignorance? For, I repeat, to escape will be impossible for us."

The marquis knitted his eyebrows, and crossed his arms with anger.

"Let us see," resumed he, with a subdued voice, but nevertheless, with trembled emotion, "let us make amend for it, Diogo."

"I ask nothing better, your Excellency."

"This is the state of the case, my lord," said he; "up to the present time we have traversed civilised countries, or nearly so, where we have only had to contend against ordinary dangers; that is to say, the bites of wild beasts or those of reptiles."
