Ten minutes later our hero was lying between the sheets, looking sleepily at the shaded electric light above him.

Meanwhile, what had become of the two men who had attempted to deprive Hal of the bag?

No sooner had the car passed in which Mr. Brindle and his young engineer were seated, than the swarthy-looking foreigners leaped on to the step of the following one, and hastily passing through the smoking-saloon, entered a small cupboard set apart for the porter.

"That was well managed, Señor Capitan," the darker of the two at once exclaimed, seating himself. "Ha, ha, did you not see them look at us? It is clear that they suspected our game, and no doubt their inspection of the cars was to discover us and have us ejected. We have played our cards well. While they fancy that we are miles behind them, we are in reality but a few yards away. No doubt this negro will entertain us till the time for action arrives, and then we will have the gold you say the bag contains, even though that stalwart young Englishman objects."

He spoke in Spanish, gesticulating and gabbling the words, and introducing a tone of marked disdain when alluding to the porter. There was little doubt that he was a half-caste, and owed some part of his existence to the negro race to which he had alluded with such contempt.

"When do we make the attempt, Señor Capitan?" he asked. "See, it is half-past eight now, and the majority of passengers are thinking of going to bed. Shall you try at midnight, or will you think it best to wait till the early hours of to-morrow?"

The man addressed did not answer for the moment, but, removing the beard from his chin, slowly rolled a cigarette. He was a small, active-looking man, of undoubted Spanish blood. At first sight he would have been called a handsome fellow, but a glance at his eyes and mouth altered that impression. There was something not altogether pleasing about him.

"You are overhasty, and forget yourself, Pedro," he said at length. "One would have thought that it was all of your planning. Remember that it was I who decided how we would act; and do not forget that in undertaking to abstract this bag, I am risking far more than you."

"For which you will, no doubt, extract a proportionately large share of the booty," grumbled the one who had been called Pedro.

"Perhaps. And why not? Am I not the leader? and are you not the servant? But do not let us argue so, or we might quarrel, and that would be bad for one of us. Listen to me, and see that you do not interrupt. This English brat, who just awoke in time to upset the plan which I had devised so carefully, is still in charge of the precious bag for which we have traveled so far, and from which we hope to recoup ourselves. We know that he is about to retire for the night, for the porter has told us so. Very good. What of the others? They are weary, and will turn in early, so as to awake fresh and rested to-morrow. Our accomplice here, the negro whom you scowl at so heavily, will tell us when all in that car have retired. That will be our time. Any noise we may make will be unnoticed, owing to the fact that it is so early; while if this young fool of an Englishman shouts—well, perhaps the rattle of the train will drown everything!"
