"And it's pretty risky, you two going alone through a country recently raided."

"How long ago were the Tubus here, do you think?" Royce asked John.

"Two free days, sah."

"Well, then, it's likely that they've gone back to their own ground. For us it's a choice of two evils, and we must chance it. With good luck, we shall get to the next village before dark. I'll engage carriers there, and we ought to be back here with plenty of grub by to-morrow night."

They set off. Both were in good condition, and they made rapid progress. But the country was trackless, and Royce could only direct his course roughly by Drysdale's map.

The short dusk was falling without their having come on any signs of human dwellings. In another half-hour it would be quite dark, and Royce reluctantly but prudently decided that they must take shelter for the night, for fear of becoming hopelessly lost, and go on in the morning.

The country was bare, consisting of rocky ground sparsely covered with scrub. It offered nothing that gave promise of a comfortable defence against the night cold, and Royce had almost reconciled himself to spending the hours in the open when suddenly he caught sight, on the crest of a low hill about a mile to the left, of what appeared to be the ruins of a small building. Such ruins are to be met with here and there in the remotest depths of the great continent, the relics of ancient civilisations long vanished. There were no signs of life about this building, and Royce resolved to take shelter there.

They struck off to the left, climbed the hill, and, after a careful survey of the neighbourhood, approached the ruin. It turned out to be a dismantled stone fort, overgrown in parts with vegetation, but in a fair state of preservation. The outer wall was complete; inside, the principal chamber, which had once, no doubt, been the headquarters of a garrison, was roofless, and such timber-work as there had been was either burnt or had been carried away. Some smaller rooms were still covered from the sky, and it was in one of these that Royce determined to repose during the night.

They had brought with them a few biscuits and a small tin of preserved mutton, and they made a meagre supper. John having noticed, as they approached the fort, the runs of ground game among the bushes, set a few snares, in the hope of providing next day's breakfast. He returned with a huge armful of leaves and grasses to spread on the stone floor of the room chosen for their night's lodging.

"It's the first time I've been littered down like a horse," said Royce to himself, with faint amusement. "There's no telling what one may come to!"
