But they did not turn off, but kept on for hours in a straight undeviating line, travelling at a fast walk. Roland Mervyn kept wondering how Mary Armstrong was bearing up. She was a strong active girl, accustomed to plenty of exercise, and at ordinary times could doubtless have walked a long distance; but the events of the day, the sudden attack upon the waggons, her capture by the Kaffirs, her uncertainty as to the fate of her father, the harrowing tortures of her companions, which she had probably been compelled to witness, and the hopelessness of her own fate, might well have broken her down. He was sure that the Kaffirs would compel her to walk as long as she could drag her limbs along, but as she was destined as a present to their chief, they might, when she could go no further, carry her. He groaned at his helplessness to aid her, and had he not had a perfect faith in the cunning of his companions, and in their ability to follow her up wherever she was taken, he would have been inclined to take the mad step of charging right in among the Kaffirs, upon the one chance of snatching her up and carrying her off from among them. Roland Mervyn, of the Cape Rifles, was a very different man from Captain Mervyn, of the Borderers. The terrible event that had caused him to throw up his commission and leave the country had in other respects been of great advantage. He had for years been haunted by the fear of madness, and whenever he felt low and out of spirits this fear of insanity had almost overpowered him. The trial had cured him of this; he had convinced himself that had he inherited the slightest taint of the curse of the Carnes, he would have gone mad while he was awaiting his trial; that he had kept his head perfect under such circumstances seemed to him an absolute proof that he was as sane as other men, and henceforth he banished the fear that had so long haunted him. It was in truth that fear which had held him back so long from entering into a formal engagement with his cousin Margaret. He looked upon it as an absolutely settled thing that they would be married some day, but had almost unconsciously shrunk from making that day a definite one; and although for the moment he had burst into a fit of wild anger at being as he considered thrown aside, he had since acknowledged to himself that Margaret's decision had been a wise one, and that it was better that they two should not have wedded. He had always been blessed with good spirits, except at the times when the fit of depression seized him; but since he had been at the Cape, and been on active duty, these had entirely passed away, and his unvarying good temper under all circumstances had often been the subject of remark among his comrades. As he rode along that night he acknowledged, what he had never before admitted to himself, that he loved Mary Armstrong. The admission was a bitter rather than a pleasant one.
