Dom Pedro groaned inwardly, but attempted a show of resolution.

"I repeat that trade is bad. It is, I fear, impossible to oblige even you."

Rideau laughed a little, but his merriment was akin to mockery.

"I can only hope you are mistaken, and this time there will be a profit. There is also another affair I would discuss with you. I am a man with a conscience, and something we are concerned in up in the bush country troubles me. It is told me that these troublesome English make protest with the Administration that when the Emir invaded their dominions his men carried good rifles which could only have been obtained from this colony. The Captain Oger stated publicly that it is a stain on the national honor, and there will be strict inquiry. I am a good friend of Dom Pedro, but first of all patriotic Frenchman, me."

There was no need to speak more plainly, because Dom Pedro understood him thoroughly, and inquired forthwith the lowest sum that would set his visitor's uneasy conscience at rest. Rideau promptly named it; and the Portuguese, being desirous of gaining time, shook his head.

"It is impossible. I also have considered about those rifles often," he said. "Now I think it would be better for me, being an innocent man, to explain to the Administration how the Emir robbed me."

Rideau was not in the least deceived, for he smiled sardonically.

"Is it not a little late, my friend, and the Commandant is a most suspicious man. It is possible he might not believe you, and it is not permitted to arm even one's carriers for protection with rifles; while there is in existence a scroll signed by the Emir and another which shows a voluntary sale. But you say what I ask is impossible. Well, I'll consider, and to-morrow may make a more feasible offer. The last time I came you entertained the sick comrade of the Englishman Maxwell. He has not given you any information about Niven's mine?"

"He did not," said Dom Pedro, with so much earnestness that Rideau did not believe him, and dismissing the subject, airily proposed another game of chess.

The next morning, Dom Pedro, being perhaps anxious to postpone the evil moment, set out for a bush village where he stated he had business; and his guest, feeling sure of his own position, was not wholly sorry to see him go. It would allow him to enjoy Miss Castro's society undisturbed, and also, if circumstances permitted, to glance through the books in her father's office, which he had long desired to do, with a view to discovering how far the man might be taxed. Dom Pedro was not a good bookkeeper, it is true, but his late partner understood his system, or rather the lack of it.
