This was somewhat in our favor. We could run where horses might not. But I took little comfort from this, for where we went the dogs would certainly follow. And we had not gone above a mile, as I reckoned, when the howling sound came to our ears--a deep-toned baying, faint and mellow, stealing through the umbrageous foliage like the horns of some fairy host. The hounds had found our scent.
Uncle Moses groaned. Doubtless he knew full well the fate of unhappy slaves who had been recaptured in flight. He quickened his strides for some yards, then, stopping, he held his hand to his side and begged me to go on alone.
"But I can not," I said. "I do not know the way; and besides, I will not leave you. Give me your musket. We have still a good start, and after you have rested a little you will be able to run again."
I took his musket, and when we set off again we were lucky to come upon a stream swirling athwart our track. We stepped into this and walked through the water for some distance, until we had, as I thought, effectually blinded our trail. And no doubt it was so, but Uncle Moses told me that it would only delay our pursuers for a little; they knew the direction of the haven for which we were making, and even if the dogs were at fault the horsemen would still press on. We wasted no more time in deflecting from our course for any such vain manoeuvers, but ran straight on.
Alas! the old man's strength was failing. He staggered, and but for my arm would have fallen. I think his collapse was due partly to terror, for the baying of the hounds was growing upon our ears; the pursuers were gaining fast upon us. I had perforce to wait patiently until the poor negro had somewhat recovered, and meanwhile the deep-mouthed baying sounded ever nearer, and the precious minutes were fleeting by. When we set off once more 'twas at little above a walking pace, and every moment I dreaded the appearance of the pursuers at our heels. And I noticed with alarm that the forest was thinning; apparently we should soon reach open country, and lose what little advantage we had in being out of our enemy's sight.
I asked anxiously whether 'twould not be better for us to turn aside into the thickets and try to hide; peradventure the dogs and the horsemen would go past. But the negro said 'twould be useless; we could not deceive the dogs, and we should be no safer than rats in a barn.
We had come to the end of what would in England be called a glen--a narrow gorge, with shelving banks rising to the height of some ninety feet, and overgrown with shrubs and creeping plants. No doubt in the rainy season 'twas the bed of a torrent; the bottom was sandy and pebbly, and hard to the feet. We had gone but a little way along it when Uncle Moses sank down, and, looking at his livid face, his panting nostrils and starting eyes, I feared that the hand of death was upon him. 'Twas clear that he was utterly spent; he could not even stagger to the farther end of the gorge; and with the bitter pangs of despair I heard the fierce baying of the hounds, and had almost resigned myself to the inevitable end.
I glanced round to see whether the pursuers were in sight. I saw, not them, but something which flashed a wild hope through me. Some little distance back a tree hung over the sandy bottom, its roots partially laid bare by the washing of the stream which had now disappeared. The trunk was inclined at a sharp angle; but little force would be needed, I thought, to topple it over until it lay athwart the path which the pursuers must follow. Its foliage was thick, and though I did not flatter myself 'twould put an end to the pursuit, I thought it might serve as a check, and enable Uncle Moses to gain strength enough for a last attempt.
Dropping the muskets by the negro's side, I ran down the gorge, scrambled up the bank to the base of the tree, and swarmed along the trunk to the farthest extremity. It was a tall tree, of a kind I did not know, and my weight upon its tapering top must have exerted a considerable force upon its loosened lower end. Catching a branch that seemed strong enough to bear me, I dropped with a jerk. There was a movement of the trunk, and I heard a wrenching sound below, but the roots still held fast. I climbed up again with the quickness I had learned at sea, and again threw myself down.
This time I produced the effect I desired; the roots gave way, and in a moment I found myself on the ground, somewhat scratched and bruised, but sound of bone and limb. The fallen tree lay full across the gorge, its foliage completely filling the space, save for a narrow gap between it and the ground, through which a man or a dog might crawl, but not a horse.
