About half past three o'clock Rollo went up to his uncle's room.

"Uncle George," said he, "have not you got almost through with your writing?"

"Why," said Mr. George, "are you tired of staying here?"

"Yes," said Rollo, "I am tired of being down in the bottom of such a deep valley. I wish you would put away your writing and go on up the river till we get out where we can see, and then you may write as much as you please."

"Do you wish to go up the river to-night?" asked Mr. George.

"Yes," said Rollo, "very much."

Mr. George took out his watch.

"Go down and ask the waiter when the next steamer comes along."

Rollo went down, and presently returned with the report that the next steamer came by at five o'clock.

"There is a place up the river about two hours' sail, called Bingen," said Mr. George, "where the mountains end. Above that the country is open and level, and the river wide. We might go up there, I suppose; but what should we do for dinner?"

"We might have dinner on board the steamer," said Rollo.

"Very well," said Mr. George; "that's what we will do. You may go and tell the waiter to bring me the bill, and then be ready at half past four. That will give me an hour more to write."

At half past four Rollo came to tell Mr. George that the steamer was coming. The trunk had been previously carried down and put on board a small boat, for this was one of the places where the steamers were not accustomed to come up to a pier, but received and landed passengers by means of small boats that went out to meet them in the middle of the river. Such a boat was now ready at the foot of the landing stairs, and Mr. George and Rollo got into it.

The boatman waited until the steamer came pretty near, and then he rowed out to meet it. He stopped rowing when the boat was opposite to the paddle wheel of the steamer, and the steamer stopped her engine at the same time. A man who stood on the paddle box threw a rope to the boat, and the boatman made this rope fast to a belaying pin that was set for the purpose near the bow of the boat. By means of this rope the boat was then drawn rapidly up alongside the steamer, at a place directly aft the paddle wheel, where there was a little stairway above, and a small platform below, both of which, when not in use, were drawn up out of the way, but which were always let down when passengers were to come on board. As soon as the boat came alongside this apparatus, Rollo and Mr. George stepped out upon the platform, and went up the little stairway, the hands on board the steamer standing there to help them. In a moment more the trunk was passed up, the boat was pushed off, and the paddle wheels of the steamer were put in motion; and thus, almost before Rollo had time to think what was going on, he found himself comfortably seated on a camp stool under the awning, by the side of Mr. George, on the quarter deck of the steamer, and sailing swiftly along on his voyage up the river.

"What sudden transitions we pass through," said, Mr. George, "in travelling on the Rhine!"

"Yes," said Rollo, "it seems scarcely five minutes ago that I was sitting, all by myself, on the bank of a lonesome river, fishing; and now I am on board a steamer, with all this company, and dashing away through the water at a great rate."

"True," said Mr. George; "and how quickly we came on board! One minute we are creeping along slowly over the water in a little boat, and the next, as if by some sort of magic, we find ourselves on the deck of the steamer, with the boat drifting away astern."

"How high the mountains are," said Rollo, "along the shores here! Do the mountains end at Bingen?"

"Yes," said Mr. George, "at Bingen, or soon after that. There the country opens, and the banks of the river become level and flat. The river widens, and there are a great many islands in it. There we come to railroads again too, for where the land is level they can make railroads very easily. It would be very difficult to make a railroad here, though I believe they are going to do it."

"I should think it would be difficult," said Rollo. "But now, uncle George, about our dinner."

"Very well," said Mr. George, "about the dinner." So the two travellers held a consultation on this subject, and concluded what to have. A few minutes afterwards a waiter came by, carrying a large salver, with some coffee and bread and butter upon it, for a gentleman on the deck. Mr. George beckoned to this waiter, and when he came to him, he ordered the dinner that he and Rollo had agreed upon. It consisted of sausages for Rollo, a beefsteak for Mr. George, and fried potatoes for both. After that they were to have an omelet and some coffee. The coffee on board the Rhine steamers, being made with very rich and pure milk, is delicious.

The waiter brought up a small square table to the part of the deck where Mr. George and Rollo were sitting, which was under the shady side of the awning, and set it for their dinner. In about twenty minutes the dinner was ready. The table itself was as neat and nice as possible, and the dishes which had been ordered were prepared in the most perfect manner. I need not add, I suppose, that Mr. George and Rollo—it being now so late—were provided with excellent appetites. So they had a very good time eating their dinner. While they were eating it they could watch the changes in the scenery of the banks, as they glided swiftly along, and observe the steamers, tow boats, and other river craft, that passed them from time to time.

While they were at dinner, Rollo asked Mr. George about the rafts, and where the timber that they were made of came from.

"Why, you see," said Mr. George, "the River Rhine, in the upper portions of it, has a great many branches which come down from among the mountains, where nothing will grow well but timber. So they reserve these places for forests, and as fast as the timber gets grown, they cut it down, and slide it down the slopes to the nearest stream, and then float it along till they come to great streams; and there they form it into rafts, and send it down the river to Holland and Belgium, where timber does not grow."

"Would not timber grow in Belgium and Holland?" asked Rollo.

"Yes," said Mr. George, "it would grow very well, but the land is too valuable to appropriate it to such a purpose. The whole country below Cologne, where we came to the river, is smooth and level, and free from stones, so that it is easily ploughed and tilled; and thus grain, and flax, and other very valuable crops can be raised upon it. They raise a few trees in that part of the country, but not many."

"I never heard of raising trees before," said Rollo, "except apple trees, or something like that."

"True," said Mr. George, "because in America, as that is a new country, there is an abundance of native forests, where the trees grow wild. But you must remember that every foot of land in Europe has been in the possession of man, and occupied by him, for two thousand years. There is not a field or a hill, or even a rocky steep on the mountain side, which has not had sixty or seventy generations of owners, who have all been watching it, and taking care of it, and improving it more or less all that time; each one carefully considering what his land can produce most profitably, and taking care of it and managing it especially with reference to that production. If his land is smooth and level, he ploughs it, and cultivates it for grass, or grain, or other plants requiring special tillage. If it is in steep slopes, with a warm exposure, he terraces it up, and makes vineyards of it. If it is in steep slopes, with a cold exposure, then it will do for timber, provided there are streams near it, so that he can float the timber away. If there are no streams near it, he can use it as pasture ground for sheep or cattle; for the wool, or the butter and cheese, which he obtains from this kind of farming, can be transported without streams; or, at least, such commodities will bear transporting farther before coming to a stream than wood or timber. Thus, you see, whatever the land is fit for, it has been appropriated to for a great many centuries; and it has all been cropped over and over again, even where the crop is a forest of trees. If we allow the trees even a hundred years to grow, before they are large enough to cut, that would give, in two thousand years, time to cut them off and let them grow up again twenty times."

"Here comes a steamer," said Rollo.

Just then the bow of a steamer came shooting into view, down the river. On the forward part of the deck were several soldiers and laborers, with women and children that looked like emigrants, and also a huge pile of trunks and merchandise covered with a tarpauling. Then came the paddle wheels, and then the quarter deck, with a large company of tourists, most of whom were looking about very eagerly at the scenery, with guide books and glasses in their hands. These were tourists that had been travelling in Switzerland, and were coming home by way of the Rhine; and as they were now just entering the part of the river where the grand and imposing scenery was to be seen,—though Mr. George and Rollo were just leaving it,—they were full of wonder and admiration at the various objects which appeared around them on every side. Rollo had but a very brief opportunity to look at these strangers, for the steamer which conveyed them passed by very swiftly, and in a moment they were gone.

"How swift!" said Rollo.

"Yes," said Mr. George, "they go down the stream much faster than they go up; for in going down they have the current to help them, but we have it to hinder us in going up."

"And does it help just as much as it hinders?" asked Rollo.

"Yes," said Mr. George, "for any given time. If the current flows two miles an hour, it will carry forward a boat that is going with it just two miles faster than it would go in still water. And if the boat is going against it, it will go just two miles an hour slower.

"Thus, you see," continued Mr. George, "if a steamer had an engine capable of driving her twelve miles an hour through the water, in navigating a stream that flows two miles an hour, she would go fourteen miles an hour in going down, and ten miles an hour in going up."

"Then," said Rollo, "it seems that the help of a current is just as much as the hinderance of it, and that a river running fast is just as good for navigation as if the water were still. Because, you see," he added, "that though they lose some headway in going up, they gain it just the same in coming down."

"That reasoning seems plausible," replied Mr. George, "but it is not sound."

"What do you mean by plausible?" asked Rollo.

"Why, it appears to be good, when it really is not so. Reasoning very often appears to be good, while there is all the time some latent flaw in it which makes the conclusion wrong. Very often something is left out of the account which ought to be taken in and calculated for, and that is the case here. The truth is, that the current helps the steamer in going down just as much as it retards her in coming up for any given time; as for instance, for an hour, or for six hours. But we are to consider that in accomplishing any given distance, the steamer is longer in coming up than she is in going down, and so is exposed to the retarding effect of the current longer than she has the benefit of its coÖperation.

"For example," continued Mr. George, "suppose the distance from one place to another, on a river flowing two miles an hour, is such that it takes a steamer three hours to go down and four hours to come up. In going down she would be aided how much?"

"Two miles an hour," said Rollo.

"And that makes how much for the whole time going down?" asked Mr. George.

"Six miles," said Rollo.

"Now, it takes her four hours to go up," said Mr. George. "How much would she be kept back then by the current?"

"Why, two miles an hour for four hours," said Rollo, "which would make eight miles."

"Thus in the double voyage," said Mr. George, "the boat would be helped six miles and hindered eight, so that the current would on the whole be a serious disadvantage. For a steamer, therefore, which is to be navigated equally both ways, the current is an evil.

"But for that sort of navigation which goes only one way, it is a great advantage. For instance, the rafts have to come down, but they never have to go back again; and so they have the whole advantage of the current in bringing them down, without any disadvantage to balance it.

"On the whole," said Mr. George, "I do not see but that the currents of great rivers are an advantage, for there is always a much greater quantity to come down than to go up. The heavy products that grow on the borders of the rivers are to come down, while comparatively little in quantity goes up. So the benefit, on the whole, which is produced by the flow of the water, may be greater than the injury."

"What do they do with the rafts," said Rollo, "when they get them down the river?"

"They break them up," said Mr. George, "and sell the timber in the countries near the mouth of the river, where but little timber grows."

By this time, Mr. George and Rollo had finished eating the meats which they had ordered for their dinner, and so the waiter came and took away the plates, and brought the omelet and the coffee. With the coffee the waiter brought two small plates and knives, and some very nice rolls and butter. He also brought a plate containing several slices of a kind of cake, toasted. This cake was very nice.

While Rollo was eating it he asked his uncle George whether, in case he had gone down the river to Boppard, and had not got back until dark, he should not have been anxious about him.

"No," said Mr. George, "not much. I took precautions against that."

"What precautions?" asked Rollo.

"Why, I sent a man with you to take care of you," said Mr. George.

"You sent a man with me?" repeated Rollo, very much surprised.

"Yes," said Mr. George, quietly. "As soon as you had gone out of my room, to go on board the raft, I called the waiter, and asked him to send a commissioner with you, to see that you did not get into any difficulty, and to take care of you in case there should be any occasion."

"Now, uncle George," said Rollo, in a mournful and complaining tone, "that was not fair."

"Why not?" asked Mr. George.

"Because," said Rollo, "I wanted to take care of myself."

"Well," said Mr. George, "you did take care of yourself—didn't you? My plan did not interfere with yours at all—did it?"

Rollo did not answer, but he looked as if he were not convinced.

"I gave the man special charge," said Mr. George, "not to interfere with you in any way, and not even to let you know that I had said any thing about you to him, so that you should be left entirely to your own resources. And you were so left. You acted in the whole affair just as you thought proper, and took care of yourself admirably well. I think especially that you were very wise in leaving the raft when you did, instead of remaining on board three or four hours longer. But however this may be, you acted for yourself throughout. I did not interfere with you at all."

"Well," said Rollo, after a moment's pause, "what you say is very true. But it seems to me it was a little artful in you to do that; and you always tell me that I must not be artful, but must be perfectly honest and open in all that I do. Don't you think you deceived me a little?"

"I do not see that I did," said Mr. George. "When we deceive a person, we do it by saying or doing something to give him a false impression, or to make him suppose that something is true which is not true. Now, what did I do or say to give you any false impression?"

"Why, nothing, I suppose," said Rollo, "except sending that man to take care of me without letting me know it."

"That was concealing something from you," said Mr. George, "not deceiving you. There are a thousand occasions when it is right to conceal things from the people around us. That is very different from deceiving them. This was a case in which I thought it best to conceal what I did, for a time, though I intended to tell you in the end. You see, I should not have done my duty, as a guardian intrusted with the care of a boy by his father, if I had allowed you to go away from me on such a doubtful expedition without some precautions. So I thought it best to send the commissioner; but I knew you wished to take care of yourself, and so I charged the commissioner to allow you to do so, and on no account to interpose, unless some accident, or unforeseen emergency, should occur. I told him not even to let you know that he was there, so that you might not be embarrassed or restricted at all by his presence, or even relieved of any portion of your solicitude. But I determined to tell you all about it as soon as it was over, and I was fondly imagining that you would praise me for my sagacity in managing the business as I did, and also especially for my openness and honesty in explaining all to you at last. But instead of that, it seems you think I did wrong; so that where I expected compliments and praise, I get only censure and condemnation; and I do not know what I shall do."

Mr. George said this with a perfectly grave face, and with such a tone of mock meekness and despondency, that Rollo burst into a loud laugh.

"If you could think of any suitable punishment for me," continued Mr. George, in the same penitent tone, "I would submit to it very contentedly; though I do not see myself any suitable way by which I can be punished, except perhaps by a fine."

"Yes," said Rollo, "a fine; you shall be fined, uncle George. There is a woman out here that has got some raspberries, in little paper baskets. You shall be fined a paper of raspberries."

Mr. George acceded to this proposal. The raspberries were two groschen a basket. Mr. George gave Rollo the money, and Rollo, going forward with it, bought the raspberries, and he and Mr. George ate them up together. They served the double purpose of a punishment for the offence, and of a dessert for the dinner.
