"That's Peter's way of remonstrating," said Jack, smiling. "It's hot here; we had better follow his example."

They did, and in a remarkably short space of time were fast asleep. The siesta had also been introduced by Jack with such success that they slept all day and sat up all night, when it was cool. It was the only way they had of making life bearable.

The next morning they were within sight of Tlatonac. A long low line of sand appeared in the distance, topped here and there with a slender palm. As they drew nearer, they saw the frowning walls of the forts rising above the waters, and beyond, on a hill, the red-roofed houses of the city. Above all, the slender towers and high dome of the cathedral.

"Hullo!" said Jack, noting the absence of the war-ships. "No navy! This looks ominous."

"Do you think war has begun?" asked Peter, turning round in dismay.

"Lord knows! It looks like it."

"Well, at all events, the war-ships can't hurt us now," said Philip; "we are under the guns of the forts."

From the central part of the forts a long wharf shot into the blue waters. The bay was covered with boats; intensely green vegetation clothed the shores, and the white walls of the forts glistening like silver in the blazing sunlight. And this was Tlatonac.

"A most exposed situation," said Philip, thinking of the war. "If the war-ships start shelling those red roofs, there won't be much of them left."

He addressed Jack; but that young man did not reply. He was thinking of Dolores. Philip turned towards Peter; but the doctor's mental eye was fixed on clouds of gorgeous butterflies. Tim!
