"Fifty of them, Sire, were they ranged up in line, one behind the other."
"Will you be able to teach us to make such weapons?"
"Your Majesty, I have had a share in the using of these weapons, but not in the making of them; and they require great skill in their manufacture. I know not whether iron stone exists in this country, and were it found it would require a long experiment and great knowledge to manufacture a cannon from it. As to the powder, it is composed of three ingredients--one is charcoal, which can be obtained wherever trees grow; another is called by us saltpeter; and the third, sulphur; but I cannot say whether either is found in this land. Nor, your Majesty, do I think that such knowledge, could I impart it, would be a blessing to the land; on the contrary, the battles would be far more terrible and bloody than they now are.

"That is good," the young king said, with animation; "though it differs altogether from our usages; but then, how are their altars of the gods to be served?"
"I believe," Roger said, "that your Majesty's grandfather erected a temple here to the Unknown God. It is the Unknown God--unknown to you, but known to us--that the white peoples across the sea worship. He is a good and gentle and loving God, and would abhor sacrifices of blood."
The king did not reply for a minute. The introduction of human sacrifices was a comparatively recent innovation in Tezcuco, and although the Aztecs had, lately, almost forced their own hideous rites upon their neighbors, there were many who were still, at heart, opposed to them. He turned the subject by saying:
