Exciting days followed, during which Marcus began to learn lessons of what it meant to advance into an enemy’s country, the necessity of being constantly on the alert, where everyone was unfriendly, and to loiter behind the main body meant being cut off, leaving the loiterer’s place in the column empty.

It was all new to Marcus, as those days passed on, and his captain followed exactly in the track of the army that had gone before, working his men hard, practising various evolutions, keeping them on the alert and ready for action at a moment’s notice.

It was on one of these occasions, many days after their start, that towards evening a halt was called just after the column had moved out from a narrow mountain ravine, such a place as had presented plenty of opportunities for the enemy, had they been near, to descend from one of the side gorges and attack, to the cutting off of the column.

And all this had necessitated careful scouting and watchfulness on the part of the leader. But at last it seemed as if they had ridden out into safety, a wide, open plain stretching before them, suitable for forming camp for the night, where there was no risk of ambush or surprise.

A murmur of satisfaction ran through the column as posts were set, fires lit, and the men began settling down. Marcus’ horses had given up a good deal of their wildness and begun to form a kind of friendship with Lupe, who had narrowly escaped execution, consequent upon the effect that he had had upon Marcus’ chariot pair, who, whenever he came near, had exhibited a frantic determination to tear off at full speed, and this generally where the ground was of the very roughest character and the destruction of the chariot would have been certain.

It had been a difficulty, but, like other difficulties better or worse, it had been mastered, and, instead of meeting his death, the constant training, through which the chariots and horsemen had passed, resulted in the above-named friendly feeling, and now, at an advance, the dog took his place just in front of the fiery little steeds and trotted before them, while when they halted, he took it as a matter of course that one or other of the beautiful little animals should stretch out its arched neck, nuzzle among his bristly hairs, and at times close its teeth upon the back of the dog’s neck and attempt to raise him from the ground.

“I should never have thought he would have stood it, my lad,” said Serge; “but he has found out it means friendly, or else he’d bark and let them have his teeth in turn.”

This was said as the sturdy driver was freeing the pair from their place on each side of the chariot pole and twisting up their traces, for night was falling fast, and the men’s fires were beginning to twinkle here and there.

“Tired, boy?” said the old soldier, who was carefully removing the dust from his armour.

“Horribly,” replied Marcus. “I want to lie down and sleep. Oh, how I can sleep to-night!”
