Forests of Maine / Marco Paul's Adventures in Pursuit of Knowledge

PREFACE

The design of the series of volumes, which it is intended to issue under the general title of Marco Paul's Adventures in the Pursuit of Knowledge, is not merely to entertain the reader with a narrative of juvenile adventures, but also to communicate, in connexion with them, as extensive and varied information as possible, in respect to the geography, the scenery, the customs and the institutions of this country, as they present themselves to the observation of the little traveller, who makes his excursions under the guidance of an intelligent and well-informed companion, qualified to assist him in the acquisition of knowledge and in the formation of character. The author will endeavor to enliven his narrative, and to infuse into it elements of a salutary moral influence, by means of personal incidents befalling the actors in the story. These incidents are, of course, imaginary—but the reader may rely upon the strict and exact truth and fidelity of all the descriptions of places, institutions and scenes, which are brought before his mind in the progress of the narrative. Thus, though the author hopes that the readers, who may honor these volumes with their perusal, will be amused and interested by them, his design throughout will be to instruct rather than to entertain.

CHAPTER I.

THE MOUTH OF THE KENNEBEC

One summer, Forester and Marco Paul formed a plan for going to Quebec. Marco was very much interested in going to Quebec, as he wanted to see the fortifications. Forester had told him that Quebec was a strongly-fortified city, being a military post of great importance, belonging to the British government. Marco was very much pleased at the idea of seeing the fortifications, and the soldiers that he supposed must be placed there to defend them.

On their way to Quebec, they had to sail up the Kennebec in a steamboat. As they were passing along, Marco and Forester sat upon the deck. It was a pleasant summer morning. They had been sailing all night upon the sea, on the route from Boston to the mouth of the Kennebec. They entered the mouth of the Kennebec very early in the morning, just before Forester and Marco got up. And thus it happened that when they came up upon the deck, they found that they were sailing in a river. The water was smooth and glassy, shining brilliantly under the rays of the morning sun, which was just beginning to rise.

The shores of the river were rocky and barren. Here and there, in the coves and eddies, were what appeared to Marco to be little fences in the water. Forester told him that they were for catching fish. The steamboat moved very slowly, and every moment the little bell would ring, and the engine would stop. Then the boat would move more slowly still, until the bell sounded again for the engine to be put in motion, and then the boat would go on a little faster.

"What makes them keep stopping?" said Marco.

"The water is very low this morning," said Forester, "and they have to proceed very carefully, or else they will get aground."

"What makes the water so low now?" asked Marco.

"There are two reasons," replied Forester. "It is late in the summer, and the streams and springs are all low; so that there is but little water to come down from the country above. Then, besides, the tide is low this morning in the sea, and that causes what water there is in the bed of the river to run off into the sea."

"Is not there any tide in the river?" asked Marco.

"No," said Forester, "I suppose there is not, strictly speaking. That is, the moon, which attracts the waters of the ocean, and makes them rise and fall in succession, produces no sensible effect upon the waters of a river. But then the rise and fall of the sea itself causes all rivers to rise and fall near their mouths, and as far up as the influence of the sea extends. You see, in fact, that it must be so."

"Not exactly," said Marco.

"Why, when the water in the sea," continued Forester, "at the mouth of the river is very low, the water in the river can flow off more readily, and this makes the water fall in the river itself. On the other hand, when the water in the sea is high, the water cannot run out from the river, and so it rises. Sometimes, in fact, the sea rises so much that the water from the sea flows up into the river, and makes it salt for a considerable distance from its mouth."

"I wonder whether the water is salt here," said Marco.

"I don't know," said Forester.

"If we had a pail with a long rope to it," said Marco, "we could let it down and get some, and try it."

"We could let the pail down, but I doubt very much whether we could get any water," said Forester. "It is quite difficult to drop the pail in such a manner as to get any water when the vessel is under way."

"I should like to try," said Marco.

"You can find out whether the water is salt easier than that," said Forester. "You can let a twine string down, and wet the end. That will take up enough for a taste."

"Well," said Marco, "if I've got a string long enough." So saying, he began to feel in his pockets for a string.

He found a piece of twine, which he thought would be long enough, but, on trial, it appeared that it would not reach quite to the water. Forester then tied it to the end of his cane, and allowed Marco to take the cane, and hold it over the side of the vessel; and by this means he succeeded in reaching the water, and wetting the end of the string. He could, after all, succeed in wetting only a small part of the string, for it was drawn along so rapidly by the motion of the boat, that it skipped upon the surface of the water without sinking in.

At length, however, after he had got the end a little wetted, he drew it up and put it in his mouth.

"How does it taste?" said Forester.

The question was hardly necessary, for the faces which Marco made showed sufficiently plain that the water was bitter and salt.

"Yes, it is salt," said he. Then, suddenly casting his eye upon a long dark-looking substance, which just then came floating by, he called out,

"Why, Forester, what is that?"

"A log," said Forester.

The log was round and straight, and the ends were square. The log glided rapidly by, and soon disappeared.

"It is a pine log," said Forester. "There are vast forests of pine trees in this state. They cut down the trees, and then cut the trunks into pieces of moderate length, and draw them on the snow to the rivers. Then, in the spring, the waters rise and float the logs down. This is one of these logs floating down. Sometimes the river is quite full of them."

"Where do they go?" asked Marco.

"Oh, men stop them all along the river, and put them into booms, and then fasten them together in rafts."

"How do they fasten them together?" asked Marco.

"They drive a pin into the middle of each log, and then extend a rope along, fastening it to each pin. In this manner, the rope holds the logs together, and they form a long raft. When they catch the logs in booms, they afterwards form them into rafts, and so float them down the river to the mills, where they are to be sawed."

"Can men stand upon the rafts?" said Marco.

"Yes," replied Forester, "very well."

"They make a floor of boards, I suppose," said Marco.

"No," replied Forester; "they stand directly upon the logs."

"I should think the logs would sink under them," replied Marco, "or at least roll about."

"They sink a little," replied Forester; "just about as much as the bulk of the man who stands upon them."

"I don't know what you mean by that, exactly," said Marco.

"Why, the rule of floating bodies is this," rejoined Forester. "When any substance, like a cake of ice, or a log of wood, or a boat, is floating upon the water, a part of it being above the water and a part under the water, if a man steps upon it, he makes it sink enough deeper to submerge a part of the wood or ice as large as he is himself. If there is just as much of the wood or ice above the water as is equal to the bulk of the man, then the man, in stepping upon it, will sink it just to the water's edge."

"But perhaps one man would be heavier than another man," said Marco.

"Yes," replied Forester; "but then he would be larger, and so, according to the principle, he would make more wood sink before the equilibrium was reached."

"What is equilibrium?" asked Marco.

"Equilibrium is an equality between two forces," replied Forester.

"I don't see what two forces there are," said Marco.

"There is the weight of the man pressing downwards," said Forester, "for one, and the buoyant power of the water, that is, its upward pressure, for the other. The weight of the man remains constantly the same. But the upward pressure of the water increases in proportion as the log sinks into it. For the deeper the log sinks into the water, the more of it is submerged, and it is more acted upon and pressed upward by the water. Now, as one of these forces remains constant, and the other increases, they must at length come to be equal, that is, in equilibrium; and then the log will not sink any farther. That's the philosophy of it, Marco."

Marco did not reply, but sat looking at the barren and rocky shores of the river, as the boat glided by them. Presently another log came into view.

"There," said Forester, "look at that log, and see whether you think that you could float upon it."

"Yes," said Marco, "I think I could."

"It depends," said Forester, "on the question whether the part of it which is out of water is as big as you are."

"I think it is," said Marco.

"Yes," added Forester, "I have no doubt that it is."

"Only I should roll off," said Marco.

"True," replied Forester; "but the millmen, who work about the logs, acquire astonishing dexterity in standing upon them. If there is only enough of the log above water to equal their bulk, so that it has buoyant power enough to float them, they will keep it steady with their feet, and sail about upon it very safely."

"I should like to try," said Marco.

"Perhaps we shall have an opportunity at some place on the river," said Forester.

Here Marco suddenly interrupted the conversation by pointing up the river to a column of smoke and steam which he saw rising beyond a point of land which was just before them.

"Here comes another steamboat," said he. "See, Forester."

"No," said Forester, "I believe that is a steam mill."

"A steam mill!" repeated Marco.

"Yes," replied Forester. "They have steam mills and tide mills to saw up the logs in this part of the river. Farther up, where there are waterfalls on the river, or on the streams which empty into it, they build mills which are carried by water. I presume that that is a steam mill."

At this moment, Marco's attention was diverted from the steam mill by a boat which came gliding into the field of view. There was one man in the boat rowing it. Another sat in the stern, with a pole in his hand. The pole had an iron hook in the end of it. A short distance before the boat was a log floating upon the water. The oarsman was rowing the boat towards the log. He brought it up to it in such a manner that the other man could strike his hook into it. When this was done, the oarsman began to pull the boat towards the shore, drawing the log with it.

By this time the whole group disappeared from Marco's view, behind a boat which was hanging on the quarter of the steamer. Marco, who wished to watch the whole proceeding, left Forester, and ran aft, in hopes that he could get another view of the men in the boat. He found, however, that the steamboat was proceeding so rapidly up the river, that he was fast losing sight of them; and then he concluded to go forward to the bows of the steamboat, thinking that, perhaps, there might be other logs coming down the river, with men after them in boats.

When he reached the bows, Marco found the deck encumbered with cables and anchors, and heavy boxes of freight, which made it difficult for him to find his way to a good place for a view. He finally reached a place where, by standing upon an anchor, he could look over the bulwarks, and get a view of the expanse of water before him. It was smooth, and its glassy surface was bright with the reflection of the rays of the morning sun.

Marco admired the beauty of the river and of its banks, but he could see no boats, or even logs coming. He saw some large sand banks before him, which had been left bare by the efflux of the tide. He wished that the steamboat would stop, and let him land upon one of them. He also looked down over the bows, and admired the graceful form and beautiful smoothness of the ripple, or rather wave, which was formed by the cutwater of the boat as it urged its way rapidly through the water. After gazing upon this for some time, Marco turned to go away in pursuit of Forester, when an occurrence took place, which being somewhat important in its consequences, the account of it must be deferred to the next chapter.

CHAPTER II.

THE LOST BUCKET

As Marco was stepping down from the position which he had taken upon the anchor, his eye fell upon a small bucket, with a long rope tied to the handle, which he immediately recognised as one of those buckets which the sailors fit up in that way, in order to draw up water from alongside the ship.

"There's a bucket, now," said Marco to himself. "I declare, I believe I'll draw up some water. Forester said that it was hard, but I think it will be easy. I'll draw up a bucket full, and carry to him and show him."

So saying, Marco took up the bucket, lifted it gently over the side, and let it down slowly by the rope into the water. There was a knot in the end of the rope; and Marco held the knot firmly in his hand, so as to draw up the bucket by means of it, as soon as he should get it full. He found, however, that, although he could let the pail down easily enough, it was no easy matter to dip up any water into it; for the rope, being fastened to the bail or handle, kept the handle, and of course the open part of the pail, upwards, so that the water could not run in. If Marco let the rope down more, the pail, being light, would not sink, but skipped along upon the surface of the water, drawn by the motion of the steamboat.

While Marco was making these fruitless attempts, another boy, dressed in sailor's clothes, whom Marco had seen several times before about the boat, came up to him, and asked him what he was doing.

"I'm trying to get some water," said Marco.

"That isn't the way to get it," said the sailor boy. "Let me have the bucket. I'll show you the way."

"No," said Marco, "I want to get it myself."

"You never can get any that way," said the boy. "You must swing it back and forth, and when it is swinging well, let it drop suddenly and catch the water."

So Marco began to swing the bucket back and forth, and after he had got it well a-swinging, he let down the rope suddenly, at the moment when the bucket was at the extent of its oscillation. The bucket filled instantly; but, as the boat was advancing rapidly, it was caught by the water with such force that the rope was twitched out of Marco's hand with great force.

"Hold on!" exclaimed the sailor boy.

But it was too late. The rope fell down into the water, and the bucket, rope and all, sailed back upon the surface of the water, until they floated under the paddle wheel of the boat, which dashed them down beneath the surface of the water, and they disappeared finally from view.

"Why did not you hold on?" said the boy.

Marco was silent.

The boy looked round to see if anybody had observed what had taken place. He found that all the seamen were busy here and there, and that nobody had noticed what the two boys had been doing.

"Nobody has seen you," said the sailor boy; "so you say nothing, and I'll say nothing."

"But suppose they ask you what has become of that bucket," said Marco; "what will you tell them?"

"Oh, I'll tell them I don't know where it is," he replied; "and I don't. I am sure I don't know where it is now: do you? Hush, here comes Joe."

Marco looked up at these words, and saw the sailor approaching whom the boy called Joe; and the boy himself immediately stepped down from the anchor, where he and Marco had been standing, and began coiling a rope upon the deck. Marco walked sorrowfully away towards the stern of the vessel, where he had left Forester.

There was something wrong and something right in the boy's proposal to Marco, to conceal the loss of the bucket. His object was to befriend and help Marco in his distress. This was right. The means by which he proposed to accomplish the object were secrecy and fraud. This was wrong. Thus, the end which he had in view was a good one, and it evinced a good feeling in him; but the means for promoting it were criminal. Some persons have maintained that if the end is only right, it is of no consequence by what means we seek to promote it. Hence, they have had this maxim, viz., "The end sanctifies the means." But this maxim is not sound. The contrary principle is correct. It is sometimes expressed by this saying: "We must not do evil that good may come;" which is a much safer proverb to be guided by.

Marco's first impulse was, to go at once and tell the captain of the steamboat that he had lost his bucket. But he did not know exactly where he could find him. He looked at his office window, and found that it was shut. He asked one of the waiters, whom he met coming up stairs from the cabin, if he knew where the captain was. But the waiter did not know. Presently, he saw a gentleman walking back and forth upon that part of the deck which is in front of the door of the ladies' cabin. He thought that he was the captain. Marco walked up to him, and accosted him by saying:

"Are you the captain of this boat, sir?"

"Am I the captain?" asked the man. "Why? What do you want to know for?"

"Because, if you are," said Marco, "I have lost your bucket."

"Lost my bucket!" repeated the gentleman. "How did you lose it?"

"I lost it overboard," said Marco.

Here the gentleman laughed, and said, "No, I'm not captain; but you seem to be an honest sort of boy. I don't know where the captain is."

All this, though it has taken some time to describe it, took place in a very few minutes; and the boat had now advanced only so far as to be opposite the steam mill which Marco had seen just before he had left Forester. Marco happened to see the mill as the boat moved by it, and he went immediately to the side of the boat to get a better view of it.

There was a chimney for the smoke, and a pipe for the waste steam, at the mill. From the steam-pipe there issued a dense column of vapor, which came up, however, not in a regular current, like the smoke from the chimney, but it was puffed up in regular strokes, making a sort of pulsation. While Marco was looking at it, Forester came along, and stood looking at it too. There were a great many logs lying about the shore, and enormous piles of boards, which had been sawed, and which were ready for the vessels that were to come and take them away.

"What makes the steam come up in puffs?" asked Marco.

"Because, it is what they call a high pressure engine," said Forester. "It works against the pressure of the atmosphere. All such engines throw out the steam in puffs."

"Why do they?" asked Marco.

"Do you know what the cylinder of a steam engine is?" said Forester.

"Not exactly; I don't remember it very well," replied Marco.

"Come with me, then," said Forester, "and I will show it to you."

So saying, he took Marco to the engine of the boat, and showed him, in the midst of the machinery, a large iron vessel, shaped like a hogshead, only it had straight sides. Marco could not see much more than the top of it.

"That is the cylinder," said Forester. "It is the heart of the steam engine, as I may say—the seat of its power. All the other machinery is only to aid the cylinder, and to convey the power to the point where it is wanted to do the work. Thus, the place where the steam exerts its power, and on which the whole movement of the machinery depends, is the cylinder."

Marco observed that a long iron rod, large and solid, and very bright, kept ascending and descending through the top of the cylinder, as if pushed up and drawn down again by some force within. Forester told him that that was the piston rod.

"The piston rod," said Forester, "is fastened, at its lower end, to the piston, which is a flat plate of iron, made to fit the inside of the cylinder exactly."

"First," said Forester, "the steam comes in below the piston, and drives it up; and then it is stopped from coming in below, and is forced in above, and so drives it down."

"And how does the other steam get out?" asked Marco.

"There are two ways of getting rid of the steam that is below the piston when the piston is coming down," said Forester. "One way is, to open a passage to let it out into the air. On this plan, when the piston has been driven up, the steam is cut off from coming in below the piston, and is admitted above. At the same instant, the passage is opened to let the lower steam out. Of course, the steam that comes in above, drives the piston down, and forces the steam that is below, out into the air. They generally have a pipe to convey it away, and as the piston goes up and down, the steam comes out in puffs, as you saw it in that mill."

"Yes," said Marco, "I understand that; and now what is the other way?"

"That kind of engine is called a high pressure engine," said Forester, "because the piston, in coming down, has to drive out the steam from below, against the pressure of the atmosphere; for the atmosphere above passes into the pipe, and resists the movement of the steam in coming out. It requires a greater force of steam to work the piston on this plan than it does upon the other."

"What is the plan of the other?" asked Marco.

"On the other plan," said Forester, "the steam under the piston is condensed, that is, turned suddenly into water; and this leaves a vacancy or void below the piston, so that the piston can be forced down much more easily than if it had to drive the steam out before it, against the pressure of the atmosphere."

Forester was going on to explain to Marco how it was that the steam was condensed in the cylinder, when the conversation was suddenly interrupted by the sound of the engine bell, which was the signal for the engine to stop. The thumping sound of the machinery and of the paddle wheels accordingly ceased, and the boat began to move more slowly. Presently, the bell sounded once more, and the piston rod slowly rose out of the cylinder, and then slowly descended again.

"They are going very slowly," said Marco.

"Yes," replied Forester, "the water is low, and I suppose that the channel is narrow."

Just at this moment, they perceived a strange sensation, as if the steamboat had been suddenly pushed backwards. Marco was startled. He did not know what it meant.

"There we are," said Forester.

"What?" said Marco. "What is it?"

"Aground," said Forester.

"Aground?" repeated Marco.

"Yes," said Forester; "that's the sensation produced when a ship goes aground upon sand or soft mud."

So saying, Forester left the engine, and went up to the upper deck, followed by Marco. There were several persons there, looking out upon the water.

"Yes," said Forester, "we are aground. You see by the trees upon the bank that we are not moving."

Marco saw that they were at rest. He asked Forester what they were going to do.

Just at this moment the little bell sounded, and the engine, which had been stopped when the boat went aground, was put in motion again.

"They are going to back the engine, I suppose," said Forester, "to try to draw her off."

But the boat would not move. The engine did not seem to have power to release her from her confinement.

"What shall we do now?" asked Marco.

"Why, whenever a ship is aground," said Forester, "the first question is, what is the state of the tide?"

"Because," continued Forester, after a moment's pause, "if the tide is rising, it soon lifts the vessel off, and enables her to go back, or, perhaps, forward, if the water is not very shallow. But, if the tide is falling, it leaves her to rest more and more upon the sand, and she cannot get off until the water has gone entirely down, and then rises again. She cannot get off, in fact, until the water has risen higher than it was when she first grounded."
