The sentry turned at once, and bowed respectfully, while he called to a comrade. The latter soon appeared, bearing some meat and fruit, and a vessel filled with native wine. He, too, paid his prisoner marked attention. "The orders are that you shall have all that you require," he said in fair Spanish. "Does my lord need anything more? A knife, perhaps, with which to cut this meat?" Roger was astounded, and looked at the man closely. A knife! Why, with that he might effect an escape. But he had hardly had time to express astonishment when the man's tone suddenly changed, though he was still polite. "This is the meal," he said, "and I have orders to supply your wants. I will return within a few minutes, and see how you are faring." He placed the dish on the ground in a shady corner, and turned to leave. Then, for the first time, Roger noticed that the sentry had softly crept through the passage, and stood at the doorway looking on. He made way for the attendant to pass, and as the latter slipped by him, Roger noticed a swift movement of his hand. It went to his lips, and he shot an expressive glance at the prisoner. "Strange," thought Roger, as he sat down to his meal, and commenced to eat, without taking notice of the sentry. "That was a signal. But the man is dressed in the uniform of these Tlascalan allies of Spain. Can he be a friend? Can Teotlili have come here already, and set the wheels in motion which may lead to my rescue?" It was impossible to answer the question, though a signal had certainly been given. Roger could scarcely swallow the food owing to excitement, for now that the merest thought of rescue had come to mind, he realized the awful position he was in, and the dread fate awaiting him. Spaniards were reputed to have little mercy, and he had lived in their country, and knew that the tale was true. "I will watch the attendant carefully," thought Roger, "and speak to him if I have an opportunity. I can see the door and some little way into the passage from here, and by moving a little to one side, I shall be able to keep an eye on the street beyond, for the sun strikes full into it, and it is brilliant. Then I can tell whether the sentry is coming or not. Yes, and I'll take no notice of the attendant, though I will speak to him."
