“Stop!” he called out to the horsemen following him.

“What is wrong?” inquired Glenarvan.

“We have stuck in the mud,” replied Ayrton.

He tried to stimulate the bullocks to a fresh effort by voice and goad, but the animals were buried half-way up their legs, and could not stir.

“Let us camp here,” suggested John Mangles.

“It would certainly be the best place,” said Ayrton. “We shall see by daylight to-morrow how to get ourselves out.”

Glenarvan acted on their advice, and came to a halt. Night came on rapidly after a brief twilight, but the heat did not withdraw with the light. Stifling vapors filled the air, and occasionally bright flashes of lightning, the reflections of a distant storm, lighted up the sky with a fiery glare. Arrangements were made for the night immediately. They did the best they could with the sunk wagon, and the tent was pitched beneath the shelter of the great trees; and if the rain did not come, they had not much to complain about.

Ayrton succeeded, though with some difficulty, in extricating the three bullocks. These courageous beasts were engulfed up to their flanks. The quartermaster turned them out with the four horses, and allowed no one but himself to see after their pasturage. He always executed his task wisely, and this evening Glenarvan noticed he redoubled his care, for which he took occasion to thank him, the preservation of the team being of supreme importance.

Meantime, the travelers were dispatching a hasty supper. Fatigue and heat destroy appetite, and sleep was needed more than food. Lady Helena and Miss Grant speedily bade the company good-night, and retired. Their companions soon stretched themselves under the tent or outside under the trees, which is no great hardship in this salubrious climate.

Gradually they all fell into a heavy sleep. The darkness deepened owing to a thick current of clouds which overspread the sky. There was not a breath of wind. The silence of night was only interrupted by the cries of the “morepork” in the minor key, like the mournful cuckoos of Europe.
