"We know where it goes to, for the sea receives them all," said Mr. Pennypacker, "but no man knows whence it comes."
"And it would take a good long trip to find out," said Sol.
"A trip that we haven't time to take," returned the schoolmaster.
Henry felt a desire to make that journey, to follow the great stream, month after month, until he traced it to the last fountain and uncovered its secret. The power that grips the explorer, that draws him on through danger, known and unknown, held him as he gazed.
They followed the banks of the stream at a slow pace to the north, sweltering in the heat which seemed to come to a focus here at the confluence of great waters, until at last they reached a wide extent of low country overgrown with bushes and cut with a broad yellow band coming down from the northeast.
"The Ohio!" said Ross.
And so it was; it was here that the stream called by the Indians "The Beautiful River"—though not deserving the name at this place—lost itself in the Mississippi and at the junction it seemed full as mighty a river as the great Father of Waters himself.
They did not stay long at the meeting of the two rivers, fearing the miasma of the marshy soil, but retreated to the hills where they went into camp again. Yet Ross, and Henry, and Sol crossed both the Ohio and the Mississippi in the frail canoe for the sake of saying that they had been on the farther shores. The three, leaving Paul and the schoolmaster to guard the camp, even penetrated to a considerable distance in the prairie country beyond the Ohio. Here Henry saw for the first time a buffalo herd of size. Buffaloes were common enough in Kentucky, but the country being mostly wooded they roamed there in small bands. North of the Ohio he now beheld these huge shaggy animals in thousands and he narrowly escaped being trampled to death by a herd which, frightened by a pack of wolves, rushed down upon him like a storm. It was Ross who saved him by shooting the leading bull, thus compelling them to divide when they came to his body, by which action they left a clear space where he and Henry stood. After that Henry, as became one of fast-ripening experience and judgment, grew more cautious.
All the party were in keen enjoyment of the great journey, and felt in their veins the thrill of the wilderness. Paul's studious face took on the brown tan of autumn, and even the schoolmaster, a man of years who liked the ways of civilization, saw only the pleasures of the forest and closed his eyes to its hardships. But there was none who was caught so deeply in the spell of the wilderness as Henry, not even Ross nor the shiftless one. There was something in the spirit of the boy that responded to the call of the winds through the deep woods, a harking back to the man primeval, a love for nature and silence.
The forest hid many things from the schoolmaster, but he knew the hearts of men, and he could read their thoughts in their eyes, and he was the first to notice the change in Henry or rather less a change than a deepening and strengthening of a nature that had not found until now its true medium. The boy did not like to hear them speak of the return, he loved his people and he would serve them always as best he could, but they were prosperous and happy back there in Wareville and did not need him; now the forest beckoned to him, and, speaking to him in a hundred voices, bade him stay. When he roamed the woods, their majesty and leafy silence appealed to all his senses. The two vast still rivers threw over him the spell of mystery, and the secret of the greater one, its hidden origin, tantalized him. Often he gazed northward along its yellow current and wondered if he could not pierce that secret. Dimly in his mind, formed a plan to follow the yellow stream to its source some day, and again he thrilled with the thought of great adventures and mighty wanderings, where men of his race had never gone before.
