Suddenly Jack became aware that Hans Schloss and his companion had stopped their talking and were staring hard at him. But he took no notice, and, still lying back in his corner, puffed heavily at his pipe.

“Who are you?” Piet Maartens suddenly asked, leaning across and jerking him by the sleeve. Then as Jack looked up he recognised him, and shouted: “The spy again! Help me, Hans, these two are Englishmen!”

Next second Jack had thrown himself upon him, and Guy rushed at the fat little German, and, grasping him by the collar, threatened to blow out his brains if he made so much as a sound.

But though Hans Schloss was no great fighter, and had given in at once with a terrified whine, the Boer was made of sterner stuff, and endeavoured to draw his pistol. Jack was too quick for him, and now, locked in each other’s arms, they swayed backwards and forwards, and finally fell to the floor with a crash, striking one of the doors heavily as they did so, and bursting it open.

“Out with him, Jack! Pitch him out! It is our only chance,” Guy cried excitedly.

Jack heard and understood his words, and, summoning all his strength, folded Piet Maartens in his arms, and, staggering to his feet, hurled him from the carriage. A moment after Guy had served the shrieking German in the same manner, and they were left alone in the carriage.

Meanwhile the train had got up speed on its long run to the Portuguese frontier, and was now well out of Pretoria and rushing across the lonely veldt.

“By Jove!” exclaimed Jack breathlessly, lifting his hat from his head and wiping the perspiration from his forehead, “that was a close shave, and if those fellows are not killed, we shall have them setting the whole country after us!”

“Then that settles it, Jack,” Guy answered with conviction. “If one or both survived the fall they will make for the nearest office and telegraph down the line to stop us. We must get out of this and make for the south.”

“Yes, you’re right, Guy. Lorenzo Marques and Delagoa Bay are out of the question, and we had better leave this as soon as possible. The train is running too fast now, but as soon as it slackens pace a little we will jump off and strike south for the other railway. We said we would go through the Orange Free State to Harrismith, and so into Natal; but I begin to think that our best route will be by way of Johnny’s Burg and on through Laing’s Nek. But there is no saying. We must do whatever seems best, but get out of this we must at all costs.”
