Ned examined the whole affair, piece by piece, from head to foot, and then he turned away from his inspection, for the room behind him was getting dim and it was time for him to look at his lamp. He took out a match as he went toward the table at the window, and in a moment more he was busy with a wick which seemed to be determined not to burn for him.

“It’s an old whale-oil lamp,” he remarked. “Mother had one, once. I remember seeing her try to light it and it would sputter for ever so long. There! It’s beginning to kindle, but it’s too big for me to carry around and hunt for books with. I wish I had a smaller one. Hullo! Here’s one of the biggest of those old concerns, right here on the table.”

It was a folio bound in vellum, and when he opened it a great deal of dust arose from the cover which banged down. Then Ned uttered a loud exclamation, and was glad he had succeeded in lighting the lamp, for there before his eyes was a vividly colored picture of a most extraordinary description. Moreover, it unfolded, so that it was almost twice the size, length, and width of the book pages.

“They are all in Spanish,” he said, “but I guess I can read them. They’re more than a hundred years old. People don’t print such books, nowadays. Nobody would have time enough to read them, I suppose, and they couldn’t sell ’em cheap enough. This is wonderful! It’s a picture of the old Mexican god, Huitzilopochtli.”

There was an explanatory inscription, and the artist had pictured the terrible deity sitting upon a throne of state, gorgeously arrayed in gold and jewels, and watching with a smile of serene satisfaction the sacrifice of some unfortunate human victims on the altar in the foreground at the right. One of the priests attending at the altar had just cut open the bosom of a tall man lying before him, and was tossing a bleeding heart upon the smoking fire, where other similar offerings were already burning.

“That must have been a horrible kind of religion,” thought Ned. “I’m glad that Cortes and his men in armor came to put an end to it. Señora Paez told me that in only a few years before he came, and her great-grandfather and his father with him, those priests cut up more than twenty thousand men, women, and children. He’s a curious kind of god, I should say, to sit there and grin while it was going on.”

He could not linger too long over one picture, however, for he had discovered that there were others in that volume which were as brilliantly colored and as interesting. On the whole, it was not necessary to hunt for anything better than this the first evening, and it appeared as if he were asking a useless question of the steel-clad warrior in the corner, when at last he turned to him to say:

“Did you ever see anything like this before? I never did. Were you there, in any of these battles? This is the way that Cortes and his cavalry scared the Indians, is it? They were awfully afraid of horses. You can buy horses for almost nothing, nowadays, anywhere in Mexico. I’ve learned how to ride ’em, too, but didn’t I get pitched off by some of those ponies! It would have scared mother half to death. I wish I could see her to-night, and show her some of these pictures. I’d like to see Bob and the girls, too. They never saw a book like this.”

He had examined a number of the pictures, and the lamp was burning fairly well, but a long time had elapsed since he came into that room, and he was not at all aware of it.

“Señor Carfora?” called out a voice in the doorway. “Oh, you are here. You did light the lamp. I was almost afraid you were in the dark.”
