“And as if it thought the Tennessee had more than it could do to drain so great a region,” said Phil, studying the map, “the Cumberland also went into the business and after pretty nearly paralleling its sister river for a great many hundreds of miles, fell into the Ohio only a few miles above the mouth of the Tennessee. The two together are longer than the Ohio itself.”
“Very decidedly,” said Ed. “And then there are all the other tributaries of the Ohio, – look at them on the map. Together they again exceed its total length.”
The boys looked at the map and saw that it was so. Then Ed resumed: —
“But, after all, the Ohio and all its tributaries combined amount to a very small part of the great system. The lower Mississippi itself from Cairo to the mouth is almost exactly as long as the Ohio. Then there are the upper Mississippi, – stretching clear up into Minnesota, – the Illinois, the Wisconsin, etc., the Missouri and its vast tributaries flowing from the Rocky Mountains, the Arkansas, the Red River, the Ouachita, the White, the St. Francis, the Yazoo, the Tallahatchie, the Sunflower, the Yalobusha – and a score of others, to say nothing of the vast bayous that connect with the wonderful river down South. Here they all are on the map. Look!”
The next fifteen minutes were given up to a study of the map, interested fingers tracing out the rivers, and a continual chatter contributing, after the manner of boys’ talk, to the general stock of information. Presently Irv Strong spoke. He had never before in his life been silent so long.
“I remember, at this stage of the proceedings, the wise remark of our honored teacher, Mrs. Dupont, that ‘eyes are excellent to see with, but one interpretative brain means more than many additional pairs of eyes.’”
“What’s all that got to do with it?” asked Constant. “She was talking about Darwin and Spencer when she said that. What’s either of them got to do with this river?”
“Ah, Constant!” said Irv, in mock melancholy. “You grieve me to the heart. You never will see the inward and spiritual meaning of my outward and visible quotations. I mean that Ed Lowry has studied out this whole thing and knows ’steen times more about it and what it means than we blockheads would find out by studying the map for a dog’s age. I venture that assertion boldly, without having the remotest notion of what constitutes a dog’s age. My idea is that we fellows ought to shut up, though I’m personally not fond of doing that, and let Ed gently distil into our minds his information about all these things. Let’s have the benefit of the ‘interpretative brain’!”
“Let’s take a header first,” cried Phil, shedding his clothes again. “I’ll beat the best of you in a swim around the boat, or if I lose, I’ll wash the dishes for a whole day.”
And with that he went head foremost overboard, Will and Irv following him.
When they reappeared on deck, blowing like porpoises and glowing like boiled lobsters, Ed said: —
“You fellows are regular water-rats; Phil is, anyhow. He’s in this water half a dozen times a day, no matter how cold the wind is.”
“That’s just it,” said Phil. “The water isn’t anything like so cold as this October air.” Then, with mock seriousness: “Believe me, my dearly beloved brother, it is to escape the frigidity of the atmosphere, or, as it were, to warm myself, that I jump into the river. You were reading a poem the other day in which the stricken-spirited scribe said: —
‘For my part I wish to enjoy what I can —
A sunset, if only a sunset be near,
A moon such as this if the weather be clear,’
and much else to the like effect. As you read the glittering, golden words, I said in my soul: ‘Bully for you, oh poet! I’m your man for those sentiments every time.’ And just now the poet and I agree that nothing in this world would minister so much to our immediate enjoyment as to jump off the boat again on the larboard side, dive clear under her and come up on the starboard. Here goes! Who’s the poet to follow me?” And overboard the boy went, feet first this time, for after striking the water and sinking to a safe depth, he must turn himself about and swim under water for fifty or sixty feet before daring to come to the surface again.
Nobody tried to perform the feat in emulation of the reckless fellow. It involved a great many dangers and a still greater many of disagreeable possibilities such as broken heads, skinned backs, and abraded shins. Of that I can give my readers full assurance because I’ve done the thing myself many times, and bear some scars as witnesses of its risks.
But it was Phil’s rule of life never to let anybody “do anything in the swimming way” that he couldn’t do equally well. He had once seen somebody dive under a steamboat and come up safely on the other side. So he straightway dived under the same steamboat and came up safely on the other side. After that, diving under a flatboat was a mere trifle to him.
CHAPTER XII
THE WONDERFUL RIVER’S WORK
“Now, then,” said Phil, wrapping a blanket around his person, for the air was indeed very chill, and prostrating himself over the map, “now, then, let the ‘interpretative brain’ get in its work! I interrupted the proceedings just to take a personal observation of the river we are to hear all about. Go on, Ed!”
“Wait a bit – I’m counting,” said Ed; “twenty-five, twenty-six, twenty-seven, twenty-eight. There. If you’ll look at the map, you’ll see that the water which the Mississippi carries down to the sea through a channel about half a mile wide below New Orleans, comes from twenty-eight states besides the Indian Territory.”
“What! oh, nonsense!” were the exclamations that greeted this statement.
“Look, and count for yourselves,” said Ed, pointing to various parts of the map as he proceeded. “Here they are: New York, Pennsylvania, West Virginia, Virginia, North Carolina, South Carolina, Kentucky, Tennessee, Alabama, Mississippi, Georgia, Ohio, Indiana, Illinois, Wisconsin, Iowa, Minnesota, North Dakota, South Dakota, Montana, Wyoming, Colorado, Missouri, Kansas, Nebraska, Arkansas, Louisiana, Texas, and the Indian Territory. Very little comes from New York or South Carolina or Texas, and not a great deal from some others of the states named, but some does, as you will see by following up the lines on the map. The rest of the states mentioned send the greater part of all their rainfall to the sea by this route.”
“Well, you could at this moment knock me down with a feather,” said Irving Strong. “Aren’t you glad, Phil, that we jumped in away up here before the water got such a mixing up?”
“But that isn’t the most important part of it,” said Ed, after his companions had finished their playful discussion of the subject.
“What is it, then? Go on,” said Irv. “I’m all ears, though Mrs. Dupont always thought I was all tongue. What is the most important part of it, Ed?”
“Why, that this river created most of the states it drains.”
“How do you mean?”
“Why, I mean that but for this great river system it would have taken a hundred or more years longer than it did to settle this vastest valley on earth and build it up into great, populous states that produce the best part of the world’s food supply.”
“Go on, please,” said Will Moreraud, speaking the eager desire of all.
“You see,” said Ed, “in order to settle a country and bring it into cultivation, you must have some way of getting into it, and still more, you must have some way of getting the things it produces out of it, so as to sell them to people that need them. Nobody would have taken the trouble to raise the produce we now have on board this boat, for instance, – the hay, grain, flour, apples, cornmeal, onions, potatoes, and the rest, – if there had been no way of sending the things away and selling them somewhere. Unless there is a market within reach, nobody will produce more of anything than he can himself use.”
“Oh, I see,” said Irv. “That’s why I don’t think more than
