"A man can't marry his grandmother."

Philip said no more; but returned to the side of Doña Eulalia, who had placed herself as far away from her duenna as was possible. This precaution was scarcely needed, as Doña Serafina had eyes for no one but Peter. She had not yet given up all hope of marriage, even at the mature age of five and forty. Peter was young and innocent; therefore Doña Serafina selected him as her victim, and under the guise of teaching him Spanish, strove to entangle him in her elderly meshes. Her eyes were still brilliant, and long experience had taught her how to use them. It was so much waste time as regards Peter. He was so impossible.

On leaving the Plaza de San Jago, the troops marched to their several quarters in the forts, and his Excellency the President went to inspect the defences of the city. Tlatonac was completely girdled by strong stone walls, and defended by heavy metal cannon, so that in the event of a sortie, particularly by a horde of naked Indians such as Xuarez's force would be, there was but little doubt that the invaders could be easily repulsed with great slaughter. As regards a land attack from the interior, this was well enough, but if Xuarez bombarded the town there was no doubt that he could speedily reduce Tlatonac to a heap of ruins. Gomez trusted to the impassable forests between the capital and Acauhtzin to protect him from an inland invasion, and as the sea-forts were defended by heavy guns, hoped to cripple the ships of the enemy before they could do much harm.

The forts defending the coast were therefore the most important in his eyes, and, after examining the interior defences, he rode down to the sea front to inspect the preparations for keeping the ships of Xuarez beyond bombarding distance of the town. Thanks to English engineers, and a lavish outlay of money, the forts were superb pieces of workmanship; and their lofty walls frowning over the bay, with the muzzles of guns protruding from their embrasures, promised a difficult task to the invaders.

Between the two principal forts was the gate of the town, which opened into a low stretch of land covered with fishing-huts, through which a road ran down to the wharf. The Bohemian was lying close under the guns of the city, so that in the event of their being discharged, she would sustain no damage; and as His Excellency rode out of the city gate, his eyes rested admiringly on the beautiful little craft.

Only momentarily, however, for at that instant a cry burst from the lips of his aide-de-camp; and Gomez looked seaward.

"The Pizarro!" he cried in surprise.

It was indeed the old ship of Don Rafael, which was steaming slowly southward, a white flag fluttering at her mainmast head. Rafael uttered an ejaculation of rage, and Gomez turned his horse to ride back into the city, not knowing with what intentions the war-ship had come.

"One moment, Señor," said Tim, catching the President's horse by the bridle; "the vessel has a white flag, so she has come with a message from Acauhtzin."

"Por Dios, we do not treat with rebels, Señor Correspoñsal."
