"If Cortes is alive he is far away; otherwise he would have heard my signal. At any rate we can do no good by waiting here. We must push on; the day approaches. As I said, I know of a place where we shall be safe."

As the grey light extended from the mountain-tops to the valleys, Fernando led them to a kind of ancient fort, constructed of great stone boulders and surrounded by a deep ditch. In the parapet of this fort there were loopholes through which to fire, and in the centre, well screened from observation, was a small hut made of the branches of trees. The redoubt stood on a sharp pinnacle of rock commanding a wide stretch of country on every hand. It had doubtless been constructed centuries before, when there was a more advanced stage of civilization in the heart of Africa. Indeed, it is from this bygone civilization that the Maziris themselves trace their origin.

As the daylight increased they were able to take in their surroundings. Many miles up the valley, it was just possible to see a little village, which, Fernando assured them, was in Maziriland itself. Some distance to the west was a great forest which extended as far as the eye could reach.

Harry looked around him in amazement.

"But this place is almost impregnable," he cried. "Four resolute men could hold it against hundreds."

"Is there water here?" asked Braid, turning to the guide.

The man pointed to a small spring which bubbled up to the surface near the door of the hut.

"I will tell you the story of this place," said he. "Years ago a party of six Maziris sought refuge in this fort, which was built in the olden times, when the Ancients crossed the deserts from the east. For eight months those six men held the army of one of the Cameroon kings at bay. They had laid in a great store of food. They made the defence even stronger. Time and again they beat back the attack."

"And in the end?" asked Jim.

"In the end four of their number were killed, but the other two escaped."
