Problem: The Ohio River, which streams westward from Pittsburgh, Pennsylvania, to Cairo, Illinois, is the largest tributary, by volume, of the Mississippi River in the United States. At the confluence, the Ohio is considerably bigger than the Mississippi (Ohio at Cairo: 281,500cuft/s (7,960m/s); Mississippi at Thebes: 208,200cuft/s (5,897m/s)) and, thus, is hydrologically the main stream of the whole river system.

The river flows through or along the border of six states, and its drainage basin includes parts of 15states. Through its largest tributary, the Tennessee River, the basin includes many of the states of the southeastern U.S. It is the source of drinking water for three million people.

It is named in Iroquoian or , "GoodRiver" or and "Spelewathiipi". The river had great significance in the history of the Native Americans, as numerous civilizations formed along its valley. For thousands of years, Native Americans used the river as a major transportation and trading route. Its waters connected communities. In the five centuries before European conquest, the Mississippian culture built numerous regional chiefdoms and major earthwork mounds in the Ohio Valley, such as Angel Mounds near Evansville, Indiana, as well as in the Mississippi Valley and the Southeast. The Osage, Omaha, Ponca and Kaw lived in the Ohio Valley, but under pressure from the Iroquois to the northeast, migrated west of the Mississippi River to Missouri, Arkansas and Oklahoma in the 17th century.

Problem: CHAPTER VII

PHIL AND BEN MAKE A MOVE So far Dave and Nat Poole had not met face to face. Our hero had seen the money-lender's son a number of times, but Nat had always been with some of his cronies and had, apparently, not taken any notice.

But on the morning following the conversation just recorded, the pair came face to face in one of the narrow hallways.

"Good-morning, Nat," said Dave, pleasantly.

"Morning," grumbled the other student. He was about to pass Dave, but suddenly changed his mind. "So you got back, eh?"

"Yes, I've been back several days."

"I heard that Link Merwell got away from you?"

"That is true."

"Humph! If I had the chance to nab him that you had, I'd not let him get away."

"We held Jasniff."

"Maybe you let Merwell go on purpose," continued the money-lender's son, shrewdly.

"Not at all, Nat. He gave us the slip, clean and clear."

"Humph!" Nat paused for a moment. "I got word from my dad that you almost smashed him up on the road with your auto."

"Hardly as bad as that."

"He is going to make your uncle pay for the damage done."

"It wasn't much."

"It was enough. You want to be more careful with your car after this. You auto fellows seem to think you own the whole road."

Problem: CHAPTER XXI

"To-day," Hamel declared, as he stood at the sideboard the following morning at breakfast-time and helped himself to bacon and eggs, "I am positively going to begin reading. I have a case full of books down at the Tower which I haven't unpacked yet."

Esther made a little grimace.

"Look at the sunshine," she said. "There isn't a breath of wind, either. I think to-day that I could play from the men's tees."

Hamel sighed as he returned to his place.

"My good intentions are already half dissipated," he admitted.

She laughed.

"How can we attack the other half?" she asked.

Gerald, who was also on his way to the sideboard, suddenly stopped.

"Hullo!" he exclaimed, looking out of the window. "Who's going away this morning, I wonder? There's the Rolls-Royce at the door."

Hamel, too, rose once more to his feet. The two exchanged swift glances. Moved by a common thought, they both started for the door, only to find it suddenly opened before them. Mr. Fentolin glided into the room.

"Uncle!" Gerald exclaimed.

Mr. Fentolin glanced keenly around the room.

"Good morning, everybody," he said. "My appearance at this hour of the morning naturally surprises you. As a matter of fact, I have been up for quite a long time. Esther dear, give me some coffee, will you, and be sure that it is hot. If any of you want to say good-by to Mr. John P. Dunster, you'd better hurry out."
