No more shots were fired at us just then. Our pursuers must have emptied their muskets; but the clatter of the horses' hoofs told us that they were hot on the chase. Our own horses were not fresh, but they were of high mettle, and responded nobly to our renewed calls upon them. Once I took an anxious look behind me, and saw that our pursuers numbered a dozen or so. They were riding hard, belaboring their mounts, with hands and feet, and I rejoiced at the sight, for I knew the great rush at the start would tell quickly upon them. "Will they overtake us?" asked Mary Desmond. "It is a matter of luck and speed," I replied, "and I will answer your question in a quarter of an hour. But remember that, come what may, I keep my word to you. I am your servant to-night." "Even if your self-sought slavery takes you into the American lines?" she asked. "Even so," I replied. "I told you my mission, though you seemed to believe it not." With this the time for conversation passed, and I put my whole attention upon our flight. My loaded pistol was still in my belt, and if our pursuers came too near, a bullet whistling among them might retard their speed. But I held that for the last resort. So far as I could see, the men were making no attempt to reload their muskets, evidently expecting to overtake us without the aid of bullets. I inferred from this circumstance that Belfort, whom I had disabled, had been the only officer among them. Otherwise they would have taken better measures to stop us. Nevertheless they pursued with patience and seemingly without fear. By and by they fell to shouting. They called upon us to stop and yield ourselves prisoners. Then I heard one of them say very distinctly that he did not want to shoot a woman. Mary Desmond heard it too, for she said,-- "I ask no favor because I am a woman. If they should shoot me, ride on with my message." I did not think it wise to reply to this, but spoke encouragingly to her horse. He was panting again, and his stride was shortening, but his courage was still high. He was a good horse and true, and deserved to bear so noble a burden. Presently the girl's head fell lower upon the horse's neck, and I called hastily to her, for I feared that she was fainting. "'Twas only a passing weakness," she said, raising her head again. "I have ridden far to-night; but I can ride farther."
