After their examination of the boat to see that everything was all right, they pulled it back into the bushes, not intending to start until the dark set in. There was a considerable supply of salted food, coffee and tea on board, but Henry and Sol killed two deer farther up the river bank which they quickly cleaned and dressed. They now thought themselves provisioned for the trip to the Falls of the Ohio, and they carried, in addition, fishing tackle which they could use at any time.
They pulled clear of the bushes about 8 o'clock in the evening and rowed down the river. But as the stream was bank full and running fast, they did not have to make any great effort. Toward midnight when they reached some of the wider parts of the river they set the sail and went ahead at a swifter pace. Henry calculated that they could reach the Ohio slightly after dawn, but as the night was uncommonly clear, with the promise of a very brilliant day to follow, they furled their sails at least two hours before sunrise, and, finding another shallow cove, drew their boat into it among the bushes.
"Now for a sleep," said Henry. "Tom and I will keep watch until noon and then Sol and Paul will take our places. At night we will start again."
"And where does my watch come, pray?" asked Mr. Pennypacker.
"We want you to help us to-night," replied Henry. "We'll need your knowledge of the sail and the oars."
"Very well," replied the unsuspicious schoolmaster. "It is understood that I do extra work to-night, because I do not watch to-day."
Henry, when he turned his face away, smiled a little. It was understood among them all that they were to spare the schoolmaster as much as possible, and to do so, they used various little devices. Theirs was a good roomy boat and those who were to sleep first disposed themselves comfortably, while Henry sat in the prow and Tom in the stern, both silent and apparently listless, but watching with eyes and ears alike. The dawn came, and, as they had foreseen, it was a bright, hot day. It was so close among the bushes that the sleepers stirred restlessly and beads of perspiration stood on the faces of the watchers. Not a breath of air stirred either in the woods or on the river. Henry was glad when it was their turn to sleep, and when he awoke, night had come with its cool shadows and a wind also that dispelled the breathless heat.
Then they pulled out of the bushes and floated again with the stream, but they did not hoist their sail. The air after the close heat of the day was charged with electricity, and they looked for a storm. It came about 11 o'clock, chiefly as a display of thunder and lightning. The flashes of electricity dazzled them and continued without a break for almost an hour. The roar of the thunder was like the unbroken discharges of great batteries, but both wind and rain were light. Several times the lightning struck with a tremendous crash in the woods about them, but the boat glided on untouched. About midnight they came out into the flood of the Ohio, and, setting their sail, they steered down the center of the stream.
All of them felt great relief, now that they were on the wide Ohio. On the narrower tributary they might have been fired upon from either shore, but the Ohio was a half mile and sometimes a full mile from bank to bank. As long as they kept in the middle of the stream they were practically safe from the bullets of ambushed Indians.
They took turns at sleeping, but it was not necessary now to use the oars. The wind was still strong, and the sail carried them at great speed down the river. They felt safe and comfortable, but it was a wild and weird scene upon which they looked. The banks of the Ohio here were high and clothed in dense forest which, in the glare of the lightning, looked like gigantic black walls on either shore. The surface of the river itself was tinted under the blaze as if with fire, and often it ran in red waves before the wind. The darkness was intense, but the flashes of lightning were so vivid that they easily saw their way.
