It was wonderful how quickly he could change himself from an unarmed English youth to one with a deadly Mauser, with ten bullets between himself and disaster. To thrust his hand beneath his coat, touch the spring, and unbutton the flap of his hidden pocket was the work of only a moment, and an instant later the pistol had by its own weight slipped out, and the butt was in his grasp, while the holster remained in its old position ready to conceal the weapon again.

Jack practised diligently with and then without the glass, and finally, feeling satisfied that he was now prepared in case of accidents, donned his hat and went out for a walk.

No one suspected him, or looked after him as though they had noticed that he was carrying hidden arms, and even Turner, when he accidentally ran across him, not only failed to perceive that Jack had something beneath his arm, but once more dilated on the possibilities of trouble in the future, and urged him to buy some weapon before returning to Johannesburg.

“You’d better do as I say, old chap,” he said persuasively. “Those Boers are bad ’uns to deal with at any time, but when they are armed and you are not—and they know it too—well, it’s apt to go hard with the poor Uitlander.”

“Ah, well, I fancy I’ll take my chance, or perhaps get a revolver next time I come south to Durban!” answered Jack with a quiet smile. “You see, from all accounts they are awfully suspicious fellows, and no one can pass into the Transvaal with so much as a cartridge; at least, that’s what I have been told.”

“Yes, Somerton, there is that difficulty about it,” Turner answered, wrinkling his forehead. “Well, I shouldn’t think that any Boer would be ass enough to search you. You don’t look the sort of fellow to smuggle arms; in fact, if you’ll excuse my saying it, old chap, you’re about the most innocent-looking and harmless young Englishman of my acquaintance. But I must be going now. So long, old horse, and mind you, if you think of that revolver, or want anything sent up to Johnny’s Burg, drop me a line, and I’ll get it forwarded to you somehow or other.”

The two young fellows shook hands, nodded, and went their different ways, Jack to various shops to carry out sundry small commissions with which Mrs Hunter had entrusted him, and Fred Turner to his office.

On the following morning Jack was whirled to the station on a rickshaw, and, leaping to the ground, paid the Zulu “boy”, who, as a matter of fact, was a fine, big, strapping man of about thirty-five, with a long scar down the side of his face, evidently the result of some old assagai stab, but which, curiously enough, served only to make a naturally jovial expression all the more pronounced.

Then he carried his bag, which contained all his purchases, to the train, and placed it on the seat he intended to occupy.

He had arrived a good ten minutes before the time announced for the departure of the Pretoria and Johannesburg express, and employed it in walking up to the engine, which he admired as a very fine specimen of machinery. Then he strolled back along the platform, dodging the passengers, who had now commenced to arrive in large numbers, and finally reached the end of the train. It was rather longer than usual, he noticed, and curiously enough, tacked on to the back of the guard’s van there were six trucks open and one closed, five of the former filled with an assortment of wooden cases labelled “Sugar”, while the sixth was loaded with a consignment of finely-broken coal.
