Every thing went on very prosperously, for a week or two, in the little study.  Marco became more and more attentive to his studies, and more and more interested in them.  He was often getting into little difficulties, it is true, and giving trouble to his uncle and aunt; but then he generally seemed sorry afterward for the trouble which he had thus occasioned, and he bore reproof, and such punishments as his cousin thought it necessary to inflict, with so much good-humor, that they all readily forgave him for his faults and misdemeanors.

One day, however, about a fortnight after he had commenced his studies, he got led away, through the influence of a peculiar temptation, into a rather serious act of transgression, which might have been followed by very grave consequences.  The circumstances were these.  He had commenced his studies as usual, after having received his half-hour’s instruction from Forester, and was in the midst of the process of reducing the fraction 504/756 to its lowest terms, when he happened to look out of the window and to see two boys climbing over a garden fence belonging to one of the neighbor’s houses, at a little distance in the rear of his uncle’s house.  It was a very pleasant morning, and Marco had the window open; so he could see the boys very plainly.  They stopped on the farther side of the fence which they had got over, and though they were partially concealed by the fence, yet Marco could plainly perceive that they were busily employed in doing something there, though he could not imagine what.  He wished very much to go and see; but he knew that it would be in vain to make request for permission, and so he contented himself with watching them.

Just at this moment his uncle opened the door which led into the little study, and asked Forester if he would step into the office.  Forester did so; and then, after a few minutes, he returned, put up his books, and said that he had got to go away, and that perhaps he should not be back till noon.  Marco had often been left alone at his studies for a time, but never for a whole morning before.  He knew that he was to go on with his work just as if Forester had remained.  So Forester bade him good morning, and then went away.

Marco watched the boys, wondering more and more what they could be doing.  They kept stooping down to the ground, and moving about a little, as if they were planting seeds.  But as it was entirely the wrong season for any such work, Marco concluded that they must be hiding something in the ground.  “Perhaps,” said he to himself, “they have been stealing some money, and are burying it.  I wish I could go and see.”

If there had been a door leading directly from the study into the yard, Marco would have left his studies and have gone out at once; but as it was, he could not get out without going through the office where his uncle was sitting.  At last the thought struck him that he might jump out the window.  He felt some hesitation at taking this step, but finally he concluded that he would do it, and just go near enough to see what the boys were hiding, and exactly where they were putting it, so that he could go afterward and find it without fail.  He determined to return then immediately.

“I shall not be out longer than five minutes,” said he to himself, “and I will let it go for my recess.”

So he took his cap from the nail where he was accustomed to hang it, while he was at his studies, and then climbing out the window, feet foremost, he let himself down gently to the ground.  He then crept slyly along through the yards and gardens, until he got pretty near the place where the boys were at work.  The mystery, however, was rather increased than diminished by the near view.  He could make nothing of the operations which they were engaged in; and while he was hesitating whether to go nearer, one of the boys happened to look up and spied him.  Marco had intended to keep himself concealed by a tree, behind which he had taken his station, but the boy having looked up suddenly, at a moment when he happened to be off his guard, saw him before he had time to draw back under the cover he had chosen.

“Holloa, Marco,” said the boy, “come here.”

Marco was astonished at this frank and open invitation.  He had expected that the boys, when they saw him, would have dropped at once behind the fence to conceal themselves, or that they would have caught up what he supposed they were burying, and have run away.  Their accosting him in this fearless manner deranged his ideas about their probable object, and increased his curiosity to know what they were doing.  So he came forth from his concealment and went toward them.  When he reached the spot, the mystery was suddenly dispelled by his finding out that they were digging worms for bait, to go a-fishing.

Marco’s curiosity was now changed to eager desire.  The boys told him that they were going down to the river to fish for eels, and Marco’s soul was all on fire to accompany them.  He had never fished for eels.  He knew the boys very well, and they offered to lend him a hook and line.  But Marco thought that on the whole it would not do.  He tried to persuade them to wait until the afternoon, but they would not consent to such a postponement of their pleasure.  So Marco wished them good luck, and began to mount the fence again, with the intention of returning to his studies.

On looking toward the office, he saw his uncle coming out of the door in the rear of it, and walking toward the house.  Marco immediately reflected that it would not answer for him to meet his uncle, and he descended from the fence again on the same side with the boys, until his uncle should go back.  The boys thought he came back because he was undecided whether to go with them or not, and they renewed their invitations with redoubled urgency.  Marco did not reply, but looked steadily toward the house.  He saw a man standing in the yard with a small ladder in his hand.  A moment afterward, Marco’s uncle came out of the house, and, to Marco’s great consternation, he perceived that he had a saw and a hatchet in his hand, and then he recollected that his uncle had been intending to prune some trees that forenoon.  The trees were situated in various positions about the yard, so that Marco could neither go in at the front door of the office, nor climb in at the window, without being discovered.  He did not know what to do.

In the mean time, the boys urged him to go with them.  They did not know any thing about his studies, and supposed that his hesitation was only owing to his want of interest in the object of the expedition.  Finally, Marco concluded to go.  He supposed that he should not be able to get back into his study till noon, as he recollected that his uncle expected to be employed all the forenoon about his pruning.  He thought, therefore, that his chance of detection would not be increased by staying out an hour or two longer, and so he told the boys that he would go.

When they had procured sufficient bait, they went toward the river.  Their way led them not very far from the house, and they were several times in situations where they were exposed to view, in case Marco’s uncle had looked toward them.  Marco, however, contrived to walk by these places in such a manner as to cover himself as much as possible from view by the other boys; and besides, he hoped that his uncle was too much occupied with his pruning, to notice what boys were prowling about the village.  They passed across the street in this manner, and then went down over the intervales toward the river.  Marco felt quite relieved at seeing that his uncle kept steadily at his work, holding the ladder for the other man to mount by, or sawing off low branches himself, without appearing to notice the boys at all.

The river was circuitous in its course, and its banks were in some places steep, and in others low and sandy.  The water was generally shallow, but in some places it was deep, ­especially under the high banks.  In many places there were willows and elms, overhanging the water.  It was in one of these places that the boys were going to fish for eels.  It was a point where the river took a sudden turn, forming a sort of angle in the stream, where the water was very dark and deep.  The bank was high at that place, and it was covered with trees and bushes.  Some of these trees had been undermined, and their roots and branches were floating in the water.  The boys scrambled down to the brink and made ready for fishing.  They cut slender poles in the bushes, for fishing-poles.  There was a trunk of a tree lying along the shore, extending obliquely out a little way over the water, which furnished them a convenient footing.  They stood or sat upon it, baited their hooks, and threw them over into the water.  They followed the bait with their eyes as it sunk slowly down into the dark depths, among the logs, and roots, and trunks of trees, which were lying submerged in the water.

The boys remained here an hour, but they caught no eels.  Either there were none there, or for some reason or other they chose not to bite.  They had some talk about going to another place, but before they decided upon that plan, Marco’s attention was arrested by the sight of what appeared to be a large log floating down the river.  He pointed it out to the other boys, and, on closer examination, they saw that it was an old canoe, of the kind that are formed by hollowing out a log.  It was not of very large size and it appeared to be rather old and decayed.  Still, the boys wanted to get it very much.  They gathered in their lines, and ran along the bank, keeping pace with the boat as it floated down.

They very soon came to a reach of the river, ­that is, to a length of it between one bend and another, where the water was swift and shallow.  So the two boys who had been fishing with Marco threw off their shoes, and pulled up their trowsers, and ran down the bank, and into the river.  The boat was far out in the stream, and they had to wade some distance before they came to it.  Besides, as the boat was floating down all the time, while they were wading across, it got some distance down the stream before they could reach it.  They, however, succeeded in getting it at last, and, with much floundering in the water and many shouts of laughter, they brought it over to Marco.

Marco was much pleased with the prize.  It was in better condition than they had expected to find it.  There was, indeed, a piece knocked out at one end, near the upper edge, but they found that it would support all three of the boys, if they sat in it carefully, and with their weight principally at the other end.  For want of oars or paddles they cut poles on the banks, thinking that they could push the boat along, by planting the poles against the bottom, as the water was not deep.  They drew the boat up to the shore, and poured out some water which had got into her, and then they all carefully embarked, intending to make a little voyage.

It happened that just below the place to which the boat had drifted before they overtook it, the water became somewhat deeper, and of course more smooth and still, so that it afforded a favorable place for navigating such a boat.  In fact, the character of the stream, throughout its whole course for several miles, was to present a constant succession of changes, from deep and almost still water, to shallow and rapid currents, rippling over beds of sand and gravel.  One of these rapids, or rips, as they were called, the boys had just passed; it being in one of them, though one more broad and less rapid than many of the others, that they had pursued and overtaken the boat.  In the smooth and still water below, therefore, they had a very favorable opportunity to try their boat, for the water, though not so shallow as it was above, was still not so deep as to prevent their propelling their boat, by pushing their poles against the bottom.  It required some care to preserve their equilibrium, but then the water was not deep, and they knew, therefore, that there was no danger of being drowned if they should upset.

Things went on very prosperously, until, after a few minutes, the boys suddenly found themselves drifting into deeper water.  Their poles would scarcely touch the bottom.  Marco, who was not much accustomed to this kind of navigation, was at first somewhat alarmed, but the other boys told him to keep quiet, and they would soon drift into shallow water again.  They accordingly drew in their poles, and began to look over the edge of the boat into the water, to see if they could see any eels.  They saw no eels, but the water soon began to grow shallow again, and so the boys, feeling that they were in no danger, remained quietly in their places, looking idly into the water, talking about the various objects which they saw upon the bottom.

After some minutes spent in this manner, one of the boys looked down the stream, and saw that the boat was gradually approaching another of the rapids.

“Come, boys,” said he, “we must go to work, or we shall be down over the rips.”

So the boys all took their poles and began to push the boat up the stream; but they found it harder than they had expected.  In fact, the boat had drifted down nearer to the rapids than they ought to have allowed it to go.  The water was running quite swiftly where they were, and they soon found that all their efforts were not sufficient to stem the current.  The boat was carried round and round in every direction, excepting up the stream.  In fact the current was rapidly acquiring the entire mastery over them, and hurrying them down to a point where the water poured on in a furious torrent through a long narrow passage between beds of stone and gravel.

“Pull, boys, pull!” said Marco; “we shall go down over the rips in spite of every thing.”

The boys did pull, but they could effect nothing.  The water was sweeping them along with great rapidity, notwithstanding all their struggles.  Finally, when they found that they could not make head against it, so as to go up the stream, they concluded to pull for the shore.  They were not in any great fear, for the river was very narrow and not more than knee deep in the rapids, so that there was no real danger of any calamity greater than getting well wet.  They seemed to be also in a fair way to escape this, for they found that they could make some progress in getting their boat toward the shore.  But, just as they began to think their object was about to be accomplished, they were arrested by a sudden mishap.  It happened that there was a little snag in the river, nearly in the direction in which they were going.  It was the end of a small log, which rose almost to the surface of the water.  The greater part of the log was firmly imbedded in the sand, but there was a small portion of it which projected so far as barely to be submerged.  The boys did not notice this, and, in their eagerness to run the boat ashore, it happened that they were running it across the current, just above this snag.  But as the current was sweeping them down the stream at the same time that they were pushing themselves across it, it carried the boat with great force against this snag.  The bottom of the boat was confined by it, while the force of the current, still pressing upon the side, overset it in a moment, and threw all the boys out into the water.

The boys scrambled out without much difficulty, and stood upon the gravelly beach.  They saw at the same moment a man on the bank of the river above, who looked as if he was about to run to their aid; but when he saw that they were safe, he turned around immediately and disappeared.  An instant afterward, Marco, finding that his cap was not upon his head, looked around for it, and, to his dismay, he saw it floating swiftly away down the rapids.  He ran into the water and seized the boat, which was then beginning also to go away.  He called upon the boys to help him pull it up and pour the water out.  He then lanched it again with all speed, seized one of the poles, clambered into it, and pushed off into the swiftest part of the current, and away he went after his cap.

He resorted to this desperate measure, because he was greatly alarmed at the idea of going home without his cap.  It would have certainly insured his detection, and, as he supposed, a double punishment.  He now was as eager to go down the rapids as he had before been to escape them.  His only care was to keep his boat head down, so that if he should encounter any snag or rock he might not be thrown broadside on.  He kept a good lookout too ahead.  The boat shot through the water like an arrow, and was soon clear of the rapids in the comparatively still water below.

Marco contrived to paddle with his pole, so as to overtake the cap and recover it.  Then he went to the shore and landed.  He drew up the boat as high as he could, and went back to seek the other boys.  He concluded that it was time to go home.  His conscience now began to reproach him with the wrong which he had been doing.  His promised pleasure had failed.  His clothes were wet and uncomfortable.  His mind was anxious and unhappy.  With a heavy heart he began to retrace his steps, sure of detection when he reached home, and of punishment.  He did not, however, dread the punishment so much as the just displeasure which his cousin would manifest, and the evidence of the pain which he knew his cousin would suffer, when he came to learn how his pupil had betrayed the confidence which had been reposed in him.  Before he set out for home, however, he took off such of his clothes as were most wet, and wrung out the water as well as he could, and then put them on again.

When he drew near to the house, he expected to see his uncle still at work, but he was not there.  Marco reconnoitered the place carefully, and then went into the office.  His uncle was not in the office.  He passed through into the study.  He was afraid that Forester would be there, but, to his surprise and joy, he was not, and there was no sign that he had been there since the morning.  Marco looked at the watch, and found that it was only about half-past eleven.  So he took down a volume of the Encyclopedia and began to read.  He read the article canoe, and he found some information about the bark canoes made by Indians, but nothing about log canoes.  In about fifteen minutes he heard the office door open, and his cousin Forester came in.  Forester walked into the study, but said nothing to Marco.  Marco kept at his work, without speaking to his cousin.  He began to hope that he might yet escape.  His only fear now was lest his wet clothes should be observed.  He put his hand down many times to his knees, to ascertain how fast they were drying.  The clothes that he wore were of woolen, and of a dark color, so that they did not show the wet very distinctly, and, besides, the sun and the air were warm that day, and the clothes had dried fast.  In a word, when twelve o’clock arrived and Marco put his books away, nobody would have observed that his clothes had been wet.  He ran about in the open air until dinner-time, and though, when he went in to dinner, he felt oppressed with a sense of guilt and of self-condemnation, he was satisfied that no one suspected him.  Marco thought that he had had a very lucky escape.
