The night had now become clear. The moon had made her appearance in the western sky; and the search might have been continued with less difficulty than before, but for the obliteration of the spoor. The dog seemed bewildered, and ran about in short broken circles, as though quite frantic at the thought of having lost the use of the most important of his senses.

“We shall have to return at last,” said Hendrik, despairingly. “We can do nothing more to-night.”

They were about to act according to this advice, when the loud roar of a lion was heard some half mile off, and in the direction from which they had just ridden. In going back that way they might encounter the fierce creature.

“I have kept the lock of my rifle as dry as possible,” said Arend, “but it may not be safe to trust it. I think I shall reload.”

Drawing the rifle out of the piece of leopard skin with which the lock had been covered, Arend pointed the muzzle upwards and pulled trigger. The gun went off.

As the report fainted away in the distance, the far-off sound of a human voice could be heard as if shouted back in answer to the shot. What they heard was the word “Hilloo.”

They hastened in the direction from whence the sound seemed to proceed. Even the dog appeared suddenly relieved from its perplexity, and led the way. In less than ten minutes they were standing around Willem, delighted at finding him in safety, and in the possession of a live giraffe.

“How long have you been here?” asked Hendrik, after the first moments of their joyful greeting had passed.

“Ever since noon,” was Willem’s reply.

“And how much longer would you have stayed, had we not found you?”
