He had reached the bridge. He looked up and down the road, and saw no human being. It was hardly time to expect the farmer yet; so he climbed down upon some dry stones in the bed of the stream, where he could watch for his coming, and be at the same time hidden from view and sheltered from the sun.

He had not been long in that situation when he heard the sounds of hoofs. It was not his white-haired farmer whom he saw approaching, but two men on horseback. They were coming from the same direction in which he was looking for the old man. As they drew near, he discovered that one was a negro. The face of the other he recognized shortly afterwards. It was that of Mr. Augustus Bythewood, who was evidently taking advantage of the fine weather to make a little journey, accompanied by a black servant.

Penn's heart contracted within him as he thought of his friend Pomp, and of the wrongs he had suffered at this man's hands. He thought of his own safety too, and crept under the bridge. He had time, however, before he disappeared, to catch a glimpse of three other horsemen coming from the north. His heart beat fast, for he knew in an instant that these were his pursuers returning.

He had already prepared for himself a good hiding-place, in a cavity between the two logs that supported the bridge. Upon the butment, close under the trembling planks, he lay, when Bythewood and his man rode over. The dust rattled upon him through the cracks, and sifted down into the stream. The thundering and shaking of the planks ceased, but he listened in vain to hear the hoofs of the two horses clattering off in the distance. To his alarm he perceived that Bythewood and his man had halted on the other side of the bridge, and were going to water their horses in the bed of the stream. Clashing and rattling down the steep, stony banks, and plashing into the water, came the foam-streaked animals. The negro rode one, and led the other by the bridle. There he sat in the saddle, watching the eager drinking of the thirsty beasts, and pulling up their heads occasionally to prevent them from swallowing too fast or too much; all in full sight of the concealed schoolmaster. Bythewood, after dismounting, also walked down to the edge of the stream in full view.

Such was the situation when the three horsemen from the north arrived. They all rode their animals down the bank into the water. Penn had not been mistaken as to their character and business. Two of them were the men who had adjusted the noose to his neck the day before. The third was no less a personage than Captain Lysander Sprowl. Penn lay breathless and trembling in his hiding-place; for those men were but a few yards from him, and all in such plain view that it seemed inevitable but they must discover him.

"What luck?" said Bythewood, carelessly, seating himself on a rock and lighting a cigar.

"The rascal has given us the slip," said Lysander, from his horse. "I believe we have passed him, and so, on our way back, we'll search the house of every man suspected of Union sentiments. He started off with Stackridge's horse, and we tracked him easy at first, but to-day we haven't once heard of him."

"It's my opinion he don't intend to leave the state," said Bythewood, coolly smoking. "Sam, walk those horses up and down the road till I call you: I want a little private talk with the captain."

The captain's attendants likewise took the hint, reined their horses up out of the water, rode over the shaking bridge and Penn's head under it, and proceeded to search the next house for him, while Sprowl was conversing with Augustus.

"Let's go over the other side," said Bythewood, "where we can be in the shade. The sun is powerful hot."
